Tremendous and infrequently adenoid cystic carcinoma of the breast without any metastasis for more than 20 years: A case report.

Breast adenoid cystic carcinoma is an extremely rare tumor that is incompletely understood, accounting for less than <0.1% of all breast cancers, with an average diameter of 3 cm, and it is extremely rare to see a large, non-metastatic breast adenoid cystic carcinoma with a diameter of about 30 cm. Since this disease is extremely rare, there are few reports in the literature and limited data on clinical diagnosis and treatment. We present a case of a 71-year-old woman with a large, non-metastatic adenoid cystic carcinoma of the left breast and share our opinion on the diagnosis and treatment of this case. A 71-year-old woman with a 20-year-old left breast mass with local bleeding and rupture for 1 hour presented to our hospital for further diagnosis and treatment. A computed tomography scan showed a large soft tissue mass shadow in the left breast and malignancy was considered. Subsequently, tissue aspiration pathology was performed and the results confirmed adenoid cystic carcinoma of the breast. Intraoperative pathology results of radical mastectomy for left breast cancer diagnosed adenoid cystic carcinoma of the breast and immunohistochemistry results of triple-negative breast cancer. Treatment of adenoid cystic carcinoma of the breast included neoadjuvant chemotherapy for breast cancer, radical mastectomy of the left breast, and postoperative chemotherapy. Initially, neoadjuvant chemotherapy for breast cancer was performed, and the TAC regimen was used to successfully reduce the size of the tumor and gain access to surgical treatment for breast cancer. The patient has recovered well after the surgery, with no wound infection or ulceration, and is now waiting for the patient's physical function to recover for postoperative chemotherapy, with no obvious discomfort. Adenoid cystic carcinoma tumors are usually around 3 cm; such a huge 30 cm adenoid cystic carcinoma of the breast is extremely rare, and it is extremely rare to find a breast malignancy that has not developed regional lymph node and distant metastases for more than 20 years. Clinicians must remain vigilant for early breast malignancies at a high age of incidence and conduct further research for diagnosis to avoid delays.

Radiographic and computed tomographic findings of intrathoracic ectopic liver in a dog.

A 5-year-old spayed female Maltese was referred due to a suspected diaphragmatic hernia. Radiography revealed a soft tissue mass in the right caudal thorax with loss of diaphragm cupola dome-shape. A diaphragmatic hernia was considered, but surgical exploration revealed an intact diaphragm and unremarkable liver lobes. CT after a surgical inspection showed all intact liver lobes and intrathoracic mass connected to the liver. The intrathoracic mass was retracted to the abdomen by incising the diaphragm. Histopathologic examination revealed hepatocellular vacuolar degeneration, indicating an intrathoracic ectopic liver. Intrathoracic ectopic liver should be included in the differential diagnosis when diaphragmatic hernia is suspected in radiography.

Oral fibrolipoma in dogs: Retrospective case series study and comparative review.

Fibrolipoma is defined as a typical lipoma transected by variable amounts of paucicellular and collagenous fibrous components. Oral and lingual fibrolipomas are well-recognized histological entities in human medicine that are slightly more prevalent in females, occur most commonly after the fourth decade, and arise from the buccal mucosa. The documentation of this neoplasm in the oral cavity is lacking in veterinary medicine. Through a multi-institutional retrospective compilation of cases submitted to diagnostic pathology services, here we describe the clinical and pathologic features of oral fibrolipomas in dogs. A total of 112 cases of oral fibrolipomas in dogs were retrieved. The mean age was 10.1 years (range 2-16 years, ±2.63 years standard deviation), with an average tumor size of 1.7 cm (range 0.2-8 cm, ±1.1 cm standard deviation). The most common location was the tongue (57.1%, 64/112), followed by the buccal mucosa (15.2%, 16/112), sublingual area (8.0%, 9/112), gingiva and lip (4.5%, 5/112 each), and palate (1 case). The anatomical location of oral fibrolipomas only differed significantly among the dog breeds (P < .001) but not among sex, age, anamnesis, or reason for submission. The tumor was most commonly reported in males (69.7%, 78/112), and in 62.5% (70/112) of the cases, the tumor was an incidental finding. Fibrolipoma should be considered a differential diagnosis when considering benign lingual and other oral soft tissue masses in dogs.

Primary Intrahepatic Mesothelioma: Case Series and Systematic Review of Literature.

Primary intrahepatic mesothelioma (PIHMM) has been rarely reported. Its typical clinical presentation, radiological features and pathology have not been defined. Here, we aimed to summarize its diagnosis and treatment. We conducted a retrospective analysis of three cases of PIHMM in the First Affiliated Hospital of Zhejiang University School of Medicine and reviewed the current literature to investigate the clinical and pathological characteristics and prognosis of PIHMM. Based on our case series and the literature, the mean age of PIHMM was 59.7 (41-83) years. Most patients present with nonspecific symptoms such as abdominal pain, fever, weight loss and weakness. On imaging, PIHMM usually presented as a solid, heterogeneous soft tissue mass with irregular margins and significant enhancement of the margins in the arterial phase. Immunohistochemical markers such as calretinin, cytokeratin (CK)5/6, D2-40, WT-1, mesothelin CK and vimentin may be useful for diagnosis. The 3-year relapse-free survival rate (RFS) was 51.85%, the 3-year overall survival (OS) rate was 83.33% and the 3-year postoperative overall survival rate was 100%. PIHMM can only be diagnosed by careful postoperative pathology, because of its nonspecific clinical presentations, serological indicators or imaging features. Immunohistochemical staining is very useful to distinguish this tumor from other liver tumors. Surgery is the mainstay of treatment.

IgG4-Related Dacryoadenitis With Fibrous Mass in a 19-Month-Old Child: Case Report and Literature Review.

A 19-month-old boy presented with eyelid swelling, proptosis, and upgaze limitation in the OD. The radiological study showed a homogeneous mass enclosing the lacrimal gland. Near-total tumor excision revealed IgG4-related orbital disease. Eosinophilia, serum IgG4, and IgE elevations were detected without extraorbital involvement. The patient received oral prednisolone for 4 months postoperatively and remained relapse-free for 27 months. Among the 17 well-documented pediatric cases of IgG4-related orbital disease in the literature (including this case), 59% were female, and the median age was 10 years; 2 patients were under 2 years old. The disease was unilateral in 82% of the patients and caused a soft tissue mass in 88%, involving the lacrimal gland in 53%. Nine patients received immunosuppression only, 4 surgery and immunosuppression, and 2 only surgical excision. Treatment results were reported in 13 patients, and all were favorable. IgG4-related dacryoadenitis with a fibrous mass may occur in very young children, responding well to surgical excision and steroids. Although pediatric IgG4-related orbital disease is not well-characterized yet, it may manifest differently from its adult variant.

Clinical Presentation and Treatment Strategies for Laryngeal Neuroendocrine Carcinoma: Insights from a Rare Case

Intriduction -Neuroendocrine neoplasms (NEN) of the larynx are very rare, accounting for &lt;1% of all laryngeal carcinomas. Based on the 2022 IARCH/WHO classification, NENs are characterised as well-differentiated neuroendocrine tumours (NET), which can further be divided into grades 1-3 based on Ki-67 levels and mitotic count, or poorly differentiated neuroendocrine carcinomas (NEC) consisting of small cell carcinoma and large cell carcinoma. In this case report, we describe a rare presentation of NEC of the larynx encountered in a 54-year-old man and how diagnostic and therapeutic dilemmas unfolded. Case description: A 6-month history of breathing and swallowing difficulties led to a tracheostomy due to stridor, in the emergency department. Imaging revealed a soft tissue mass involving the supraglottic larynx but no significant associated cervical lymphadenopathy. The biopsy from the growth was suggestive of poorly differentiated NEC as an AJCC stage cT3N0M0. However, there was local progression post-initial treatment with vincristine, doxorubicin and cyclophosphamide (VAC). The chemotherapy regimen was switched to carboplatin and etoposide. The patient received definitive radiation therapy and completed the planned dose of radiation.After 10 months of disease-free interval, there was local recurrence with lung nodules that prompted rechallenge with platinum and etoposide. The patient is doing well and remains clinically and radiologically stable to maintenance therapy with carboplatin &amp; etoposide. Conclusion: NENs of the larynx and especially NECs, are difficult to diagnose as they are rare and have varied molecular profiles. Its management frequently calls for multimodal approaches with chemotherapy and radiation therapy. Due to the developments in diagnostic and therapeutic modalities, our knowledge of NENs has been enhanced which contributed to better practice standards. Nevertheless, standardized treatment strategies remain to be determined by large cohort studies and comprehensive molecular profiling that can determine improved clinical outcomes.

[Translated article] Diagnostic imaging in patients with vertebral compression fractures

Vertebral compression fractures by osteoporosis (OVF) is usually a diagnostic problem and coincides on the age group of metastatic vertebral compression fractures (MVF). Although radiography is the first diagnostic technique, generally is not accurate for depicting demineralization and soft tissue lesions. Magnetic resonance (MRI) is the diagnostic choice. The most relevant signs are intravertebral fluid collection or fluid signal, other vertebral deformities without oedema and older age. Among the most relevant findings for diagnosis MVF are soft tissue mass and pedicle intensity signal asymmetries. However, reproducibility of these findings in clinical practice is moderate.

LOW-GRADE SINONASAL FIBROSARCOMA : A CASE REPORT

Fibrosarcoma is a rare malignant tumor. The sinonasal localization is extremely uncommon.Theclinical presentation is similar to other neoplasms of this region, consisting of nonspecific symptoms such as epistaxis and nasal obstruction. Definitive diagnosis is obtained on the basis of histopathology and immunochemistry.This isthe case of a 40-year-old woman with a six months complaint of left nasal obstruction, recurrent epistaxis, hyposmia and cephalalgia. Nasal endoscopy revealed a regular pink soft-tissue mass filling the left nasal cavity. CT scan and MRI showed a well-defined, irregularly contoured tissue tumor,occupying the left nasal fossa, with matrix of calcifications within the tumor.A biopsy was performed, and the histopathological findings revealed a low-grade fibrosarcoma with spindle-shaped cells arranged in a herringbone pattern. The immunohistochemistry was positive for vimentin staining. The tumor was completely resected with free margins using the endoscopic endonasal approach. No adjuvant radiotherapy was prescribed.The patient is disease-free at a regular five-year postoperative follow-up.Only few cases of sinonasal fibrosarcoma has been reported in literature. There are no specific symptoms or imaging features. Still, this is the first case describing intra-tumoral calcifications. The mainstay of treatment is surgical excision with radical margins.Radiotherapy may be adjunctive in cases of positive margins or incomplete resection.

Diagnostic Efficacy of Dynamic Maneuver in Contrast-Enhanced Computed Tomography Compared With Conventional Contrast-Enhanced Computed Tomography in Imaging the Neck Region.

Introduction Dynamic contrast-enhanced computed tomography (DCE-CT) and conventional contrast-enhanced computed tomography (CE-CT) are widely used to evaluate neck lesions, including lymph node metastases, thyroid nodules, salivary gland tumors, and other soft tissue masses. DCE-CT, which captures multiple phases of contrast enhancement over time, is hypothesized to provide superior diagnostic accuracy compared to the single-phase images obtained by CE-CT due to its ability to offer dynamic information about tissue perfusion, blood volume, and vascular permeability. Methods This retrospective observational diagnostic study included 100 patients who underwent neck imaging, divided equally into DCE-CT and CE-CT groups. Patient demographics (age, gender, body mass index) and lesion characteristics (type, location, size, enhancement pattern, margins) were recorded. Diagnostic performance metrics (sensitivity, specificity, accuracy, positive predictive value, negative predictive value) were evaluated alongside inter-observer variability using the kappa statistic. Clinical impact was assessed based on changes in treatment plans and improvements in patient outcomes. The radiation dose for each modality was documented. Statistical analysis was performed using SPSS software (IBM SPSS Statistics for Windows, IBM Corp., Armonk, NY) with chi-square tests for categorical variables and t-tests for continuous variables. Results The study included 58 males and 42 females with a mean age of 55.5 years. A total of 145 lesions were detected: 75 by DCE-CT and 70 by CE-CT. DCE-CT demonstrated higher sensitivity (93.33%) and specificity (96.00%) compared to CE-CT (sensitivity 86.67%, specificity 92.00%). The accuracy of DCE-CT was 94.00% versus 88.00% for CE-CT. Inter-observer agreement was higher for DCE-CT (kappa = 0.85) compared to CE-CT (kappa = 0.80). DCE-CT led to treatment plan changes in 40% of cases and resulted in a 75% improvement in outcomes compared to 25% and 60%, respectively, for CE-CT. The mean radiation dose was slightly higher for DCE-CT (8.5 mSv) compared to CE-CT (7.0 mSv). Conclusion DCE-CT offers superior diagnostic efficacy compared to CE-CT for imaging neck lesions with enhanced sensitivity, specificity, and accuracy. Its ability to capture multiple phases of contrast enhancement allows for detailed lesion characterization and provides crucial quantitative data on tissue perfusion and blood volume. These benefits lead to more frequent improvements in patient outcomes and changes in treatment plans. Despite the slightly higher radiation dose, the diagnostic advantages of DCE-CT outweigh the disadvantages, particularly in complex cases requiring detailed lesion analysis. Further prospective studies are recommended to validate these findings and explore the broader clinical benefits of DCE-CT.

Radiographic and ultrasonographic appearance of pyometra with unilateral uterine torsion in a domestic shorthair cat.

An 8-year-old female domestic shorthair, presenting for a 3-day history of lethargy and hyporexia, was obtunded, dehydrated, tachypneic, and had abdominal distension on physical exam with no vaginal discharge or pyrexia. Abdominal radiographs revealed a large, ovoid soft tissue mass and a tortuous, tubular soft tissue structure in the abdomen. Abdominal ultrasound revealed a severely fluid-distended uterus with a left uterine torsion, which was demonstrated by a "whirl sign." Emergency ovariohysterectomy surgically confirmed a 360° torsion of the left uterine horn with a fluid-distended right uterine horn. Histopathology confirmed a diagnosis of pyometra, and the cat recovered uneventfully.

Sinonasal Leiomyoma: A Case Report and a Review of the Literature

Abstract Sinonasal leiomyoma is an exceptionally rare neoplasm arising from smooth muscle cells within the sinonasal tract. This abstract presents a case study of a 43-year-old male patient diagnosed with sinonasal leiomyoma, a distinctive and challenging entity in otolaryngology. The patient presented with a complex clinical history, including a 2-year interval between initial evaluation and definitive diagnosis. Initial histology suggested a smooth muscle tumour of uncertain malignant potential, highlighting the diagnostic intricacies associated with this condition. The radiological assessment revealed an extensive soft tissue mass with the involvement of multiple adjacent structures. The patient subsequently underwent surgical resection, leading to a revised histological diagnosis of leiomyoma. This case underscores the diagnostic challenges associated with sinonasal leiomyoma, emphasising the importance of comprehensive evaluation, including clinical history, radiological imaging, and histopathological examination. Long-term follow-up is essential for monitoring potential recurrences and optimising patient outcomes. By presenting this rare case, we aim to contribute to the limited body of literature on sinonasal leiomyoma and highlight the complexities surrounding its diagnosis and management in clinical practice.

Primary alveolar soft part sarcoma of the ilium: A case report and literature review

Introduction: The primary alveolar soft part sarcoma (ASPS) of bone is extremely rare, and the number of published reporting cases is limited. Case Report: We present a 30-year-old woman with primary ASPS of ilium. Computed tomography and magnetic resonance imaging revealed a destructive and moth-eaten appearance in the ilium with a soft tissue mass. 18F-fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) revealed high uptakes of FDG in the left ilium. ASPSCR1-TFE3 gene fusion was detected by reverse transcriptase polymerase chain reaction (RT-PCR). Wide resection was performed. One year after the surgery, a local recurrence developed. However, there has been no evidence of disease in the last eight years after the second surgery. Conclusion: 18F-fluorodeoxyglucose positron emission tomography-computed tomography and RT-PCR besides routine radiological and histopathological studies helped achieve the accurate diagnosis and provide appropriate treatment in the present case.

Body composition and phase angle in rugby union athletes: A comparison between forward and back positions

IntroductionRugby union has been increasingly attracting a multitude of enthusiasts over the past years. Nevertheless, there is a need for a more profound understanding of body composition, particularly regarding body fluids, and phase angle by playing position in rugby union athletes. MethodsThis study aimed to compare body composition components and phase angle among rugby union athletes based on their playing positions (forwards vs. backs). The sample consisted of 26 male athletes from rugby union clubs in Florianópolis, Brazil. Body composition [fat mass, lean soft tissue mass (LSTM)], body fluids (total body water, intra and extracellular water, and their proportions) and phase angle were evaluated using dual emission X-ray absorptiometry and bioelectrical impedance analysis, respectively. Statistical analysis was carried out using the analysis of covariance to compare body composition, and phase angle between playing positions (forwards vs. backs). ResultsThe primary findings indicated that rugby union athletes playing as forwards demonstrated higher values for fat mass, FFBM, and body fluids (total body water, intracellular, and extracellular water) compared to those playing as backs (p < 0.01). No difference was observed between playing positions for the other variables. ConclusionsBody composition may vary depending on the playing position in rugby union athletes.

Soft tissue hemangioma of the right upper extremity with intraosseous extension and secondary intravascular papillary endothelial hyperplasia.

Intravascular papillary endothelial hyperplasia (IPEH), also known as Masson's tumor, is an uncommon exuberant form of organizing thrombus that may occur within a vessel, vascular tumor, or hematoma and may change the imaging appearance to mimic an aggressive process. It must be distinguished pathologically from angiosarcoma. They have been most commonly reported within superficial soft tissue tumors, and rapid growth and effect on bone are rarely described. We present a case of a patient with a soft tissue hemangioma with IPEH with intraosseous extension that presented with a pathologic fracture of her right humerus with an aggressive appearing osseous lesion. CT and MRI demonstrated a multifocal ill-defined soft tissue mass throughout the right upper extremity with underlying cortical tunneling and scalloping of the proximal humerus. Similar imaging findings were also present in the distal humerus and ipsilateral scapula and evolved during her hospitalization. Following percutaneous biopsy revealing hemangioma with features of papillary endothelial hyperplasia with intraosseous extension, the patient died in the ICU secondary to unrelated septic shock. Diagnosis was confirmed at autopsy. Primary and secondary IPEH have been generally characterized as well-defined solitary masses, most often in the superficial soft tissues. This case of a deep soft tissue hemangioma with type II IPEH, intraosseous extension, and imaging findings of regional multicompartmental involvement is very unusual. Reporting of this case in the literature should be beneficial for pathologic correlation with similar confounding masses as well as propose a possible mechanism for intraosseous extension of soft tissue hemangiomas.

Concurrent primary extranodal marginal zone lymphoma and malakoplakia in the vagina: pearls and pitfalls

Primary lymphomas of the female genital tract are rare, representing approximately 1% of extranodal lymphomas. The most common histological subtype is diffuse large B-cell lymphoma, followed by follicular lymphoma. Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) in the female genital tract is rare and usually discovered incidentally. While MALT lymphoma is often linked to infections or autoimmune diseases, its cause in the female genital tract is generally unknown. On the other hand, malakoplakia is a chronic inflammatory condition resulting from an impaired histiocytic response to common bacterial infections. In this report, we present an extremely rare case of concurrent primary MALT lymphoma and malakoplakia in the vagina of a 79-year-old woman who exhibited postmenopausal bleeding and a soft tissue mass. Tissue examination revealed malignant lymphoid cells obscured by abundant inflammatory cells interspersed with numerous blood vessels, mimicking granulation tissue. A significant diagnostic challenge lies initially in missing the concurrent presence of malignant lymphoma and malakoplakia. Therefore, we emphasize the importance of clinicopathological correlation to accurately diagnose these rare conditions.

Primary Presacral Neuroendocrine Tumors Presented by Lumbosacral Pain: a Case Report

Primary presacral neuroendocrine tumors (NETs) are exceedingly rare and often present with extensive metastases, posing significant challenges for clinical management. We report a case of a presacral neuroendocrine tumor in a 68-year-old male who presented with lumbosacral pain. Enhanced MRI revealed a soft tissue mass at the sacrococcygeal region, while whole-body enhanced 18F-PET/CT identified small intratumoral vessels and involvement of the adjacent rectal posterior wall, mesorectal fascia, presacral fascia, and sacrococcygeal bones, accompanied by multiple lymph node metastases and widespread metastases to the lungs, liver, and bones. A CT-guided biopsy confirmed the diagnosis of a grade 2 (G2) neuroendocrine tumor. Given the tumor's extensive metastasis and aggressive nature, surgical intervention was deemed unsuitable, and the patient was treated with sulfatinib. Sulfatinib shows significant potential in managing advanced neuroendocrine tumors, providing an effective therapeutic option for patients with such complex and high-risk conditions.

Ultrasound Evaluation of Soft Tissue Masses and Parotid Gland in Clinical Rheumatology.

Soft tissue masses are very common and may appear in the context of rheumatic diseases. They usually occur alone but may occasionally be part of the syndromes and can sometimes involve periarticular tissues. Soft tissue masses can be divided into several categories. In this article, we have categorized them into 3 different groups: (1) pseudotumors, (2) benign tumors, and (3) malignant tumors. Parotid enlargement will also be discussed in this study. The majority of Soft tissue masses are pseudotumors or benign tumors, which can be easily characterized with ultrasound, therefore, considered the first screening tool in the study of this type of lesion. If the tumor is deep or poorly accessible, or present with suspected signs of malignancy, the sonographer may suggest expanding the study with magnetic resonance imaging and/or an ultrasound-guided biopsy of the lesion. Ultrasound is also a good technique for the parotid and submandibular glands and is very useful for evaluating and monitoring Sjogren's syndrome.

Oral mucocele: A narrative review

A mucocele stands out as the most prevalent mucosal lesion found in the oral cavity. It is characterized as a cyst filled with mucus that can manifest within the oral region. This condition arises from the buildup of mucus secretion triggered by the factors such as trauma, habits like lip-biting, or changes in minor salivary gland function. Oral mucoceles (OMs) represent benign masses of soft tissue, typically appearing as smooth, spherical, translucent nodules with a soft consistency, commonly observed in the buccal mucosa or lips. OM can manifest anywhere within the oral mucosa, including the lips, cheeks, and floor of the oral cavity, although it predominantly occurs in the lip region. There are two primary types of OMs such as extravasation and retention types. OM mostly affects young patients but can affect all groups. OMs typically present as asymptomatic, although occasionally they may cause discomfort by hindering chewing, speech, or swallowing. The diagnosis of OM is based on the clinical appearance and history. The histopathological study confirms the diagnosis of OM. Treatment options for OM encompass various approaches such as complete excision, marsupialization, cryosurgery, carbon dioxide laser therapy, electrocautery, and intralesional injection of sclerosing agents. This review focuses on details of OM including its etiopathology, classification, clinical features, and its current management.

Characteristics and Prevalence of Surgical Diseases in Avian Species within Aydın Province: A Study of Domestic and Wildlife Birds

Objective: The aim of this study is to present descriptive information on surgical cases observed in avian species. Materials and Methods: The study included a total of 125 domestic and wild avian species of various ages, genders, species, and breeds, which were presented to the clinics of the Department of Surgery, Faculty of Veterinary Medicine, Aydın Adnan Menderes University. Species, breed, age, and gender information were recorded for each animal, and comprehensive clinical examinations, including inspection, palpation, percussion, auscultation, and radiography, were performed to assess their overall condition. Definitive, suspected, or symptomatic diagnoses were established, and diseases were categorized and presented under specific headings such as fracture, dislocation, infection, soft tissue injury, mass, wound, paralysis, and other diseases. The medical and/or surgical treatments were administered based on the specific disease classification. Results: The study material consisted of a total of 125 avian cases, which were categorized and evaluated as follows: 53 [n=53 (42.4%)] fractures, 2 [n=2 (1.6%)] luxations, 13 [n=13 (10.4%)] infections, 11 [n=11 (8.8%)] soft tissue injuries, 12 [n=12 (9.6%)] masses (cysts/tumors), 22 [n=22 (17.6%)] wounds, 6 [n=6 (4.8%)] paralysis cases, and 6 [n=6 (4.8%)] other diseases. Conclusion: This study provides insights into the prevalence and clinical presentations of surgical diseases in avian species. It also offers valuable information regarding the diagnosis and treatment of these conditions.

Pleomorphic Adenoma in the Nasal Cavity: Case Report and Review of Literature.

Pleomorphic adenoma (PA) represents the most frequently occurring benign tumor within both major and minor salivary glands. However, in rare instances, nasal PA is an epithelial-derived borderline tumor, often originating from the nasal septum. Diagnosis usually relies on histopathological analysis. Under general anesthesia, these rare nasal tumors can be completely resected via endoscopic surgery. This article reports a case of PA originating from the nasal septum in a 49-year-old patient presenting with nasal congestion, along with a brief review of the current literature. The diagnostic nasal endoscopic examination showed a pink neoplastic mass in the left nasal cavity. Subsequent radiologic examination demonstrated a soft tissue mass in the anterior part of the nasal septum. After complete resection under nasal endoscopy, histopathological examination confirmed it as PA. Fortunately, no related complications occurred perioperatively and postoperatively. After surgery, performing a thorough examination with nasal endoscopy and scheduling regular follow-ups are crucial steps to prevent local recurrence.
