Vulvar ductal carcinoma in situ as a manifestation of ectopic breast tissue.

SynopsisThe fourth known occurrence of ductal carcinoma in situ found in ectopic breast tissue of the vulva successfully treated with wide‐excision biopsy and anastrozole.

Axillary ectopic breast tissue in the adolescent.

Ectopic breast tissue (EBT) includes a spectrum of disease that entails other entities based on the presence of glandular tissue, nipple, or areola. The diagnosis in adolescents is infrequent. A retrospective study was performed including girls with axillary EBT (class IV or V of Kajava's Classification) operated in 2006-2020. Imagining studies, clinical and surgical reports, and histopathology were reviewed. Eleven girls from 13 to 16years old were included. Two patients (18.2%) presented bilateral EBT. The most frequent clinical manifestation was 2-5cm mass (100%), associating cyclic pain with menstruation (45%) and fluctuating volume (36%). Bilateral axillary ultrasonography allowed preoperative diagnosis. All of them were treated by open excision, through small incisions located in an axillary y fold. Clinical and aesthetic results were self-assessed as "very good", with normalization of the axillary y hollow and imperceptible scars. No recurrences were observed after one year of follow-up. An immediate postoperative hematoma was reported, which did not require drainage. Histopathology showed mature breast tissue without atypia. Axillary accessory breasts must be included in differential diagnosis of pediatric axillary masses. Bilateral ultrasonography is recommended for the preoperative diagnosis. Excision through minimal incision at this age seems to be safe and effective.

A case of ectopic fibroadenoma mimicking left axillary lymphadenopathy

Fibroadenomas are the most common benign tumors of the breast. Since they originate from the fibroglandular breast tissue, they cannot be localized anywhere outside the breast. However, they can be localized in accessory or ectopic breast tissue and cause confusion in terms of clinical differential diagnosis. Small ectopic fibroadenomas placed in normal breast tissue are generally asymptomatic and nonpalpable. In contrast, lesions located in the axillary region are usually palpable, due to their superficial location and skin that is thinner at this level. This case report presents the clinical and imaging findings of a patient with a preliminary diagnosis of lymphadenopathy, with a superficial axillary location of the lesion and who underwent biopsy. In our case, no obvious accessory breast tissue was detected by physical examination or ultrasound of the left armpit. Even though there was axillary accessory breast tissue, it was not at a level that could be detected by ultrasound.

A Rare Case of Fibroadenoma in an Accessory Breast over Anterior Chest Wall

Accessory breast tissue is an uncommon condition which occurs in 0.4–6% of women. It is mostly located in the axilla where it can cause diagnostic difficulty, especially if it is unilateral and large. Usually it is bilateral and presents as an asymptomatic mass during pregnancy or lactation. The diagnosis of ectopic breast tissue is important as it can undergo the same pathological changes that occur in a normal breast, such as mastitis, fibrocystic disease and carcinoma. We present a case of unilateral accessory breast without nipple and areola over anterior chest wall with a fibroadenoma inside it in a 20 year old lady.

Axillary Ectopic Breast Tissue Primary Cancer: A Rare Presentation of a Common Disease

Background: Carcinoma of ectopic breast tissue represents a rare condition. Ectopic glandular tissue is frequently located in the axilla, so ectopic breast lesions must be distinguished from other subcutaneous masses arising in this location. Case presentation: We describe the case of e 75 y/o woman presented to our department for the recent manifestation of an axillary cutaneous lesion. She underwent mammogram, breast ultrasound, fine-needle aspiration citology, breast MRI, thoraco-abdominal CT-scan and punch biopsy, and she was subsequently treated as a CUP-syndrome case. The final pathologic report showed the evidence of an ectopic breast tissue cancer. Conclusion: Despite the rarity of this condition, physicians should always keep in mind the possibility of ectopic BC in order to make an early diagnosis and adequately treat these patients.

Rare Case of Fibroadenoma within Ectopic Breast Tissue in Axilla – A Case Report and Review of Literature

The congenital anomalies of breast, especially the polymastia (supernumerary breast) and polythelia (supernumerary nipple), can have varied presentations, associated renal anomalies, and pathologies arising from them. The axillary polymastia is a variant of ectopic breast tissue (EBT). Ectopic breast tissue can undergo the same physiological and pathological processes as the normally located breast. The incidence of fibroadenoma developing in ectopic breast is reported as a rare entity, the most common being the carcinoma. Here we report a case of fibroadenoma developing in ectopic breast tissue located in axilla.

Vulval fibroadenoma, a common tumor at an uncommon site - A case report with review of literature

Vulval fibroadenoma is a rare benign tumour arising from anogenital mammary like glands. Vulva is an uncommon site for fibroadenoma. This is a case of 33 year old female presented with well defined mass in the right labia majora with a histopathological diagnosis of Vulval fibroadenoma confirming origin from ectopic breast tissue.

Experience of Ultrasound-Guided Vacuum-Assisted Excision of a Phyllodes Tumor Arising From Ectopic Axillary Breast Tissue: A Case Report

: An axillary breast is a common condition, which can cause various diseases arising from the breast tissue. Among these diseases, phyllodes tumors are very rare fibroepithelial tumors, which resemble fibroadenomas. Surgical removal is the treatment of choice for phyllodes tumors to prevent recurrence. Inpatient treatment and general anesthesia are required for surgical removal, and fibrosis, skin scarring, and neurological symptoms may occur after surgery. Ultrasound-guided vacuum-assisted excision, because of its advantages, is an alternative to surgical excision for clinically benign breast masses. Therefore, in cases of clinically benign or concordant benign lesions, following a core needle biopsy, ultrasound-guided vacuum-assisted excision can be considered with sufficient preoperative measures and close follow-up of the ectopic axillary breast.

WITHDRAWN: Bilateral axillary tumour in a 12-year-old girl: a case report

Ectopic breast tissue is a rare condition in the Caucasian population. The most frequent form is polythelia (supernumerary nipples), whereas polymastia (complete supernumerary breasts) is more uncommon. They are usually benign asymptomatic lesions that go undetected until pregnancy or lactation. However, they are under the same hormonal influence as normal breast tissue and therefore are susceptible to malignant changes. a 12-year-old girl presented bilateral axillary polymastia and polythelia, detected with puberal changes. Surgical removal was postponed until the end of puberal development. Polymastia is a rare condition that can have psychological consequences, especially in adolescents. It has been associated with other malformations and malignant tumours, so surgical removal is usually recommended.

Primary ectopic axillary breast cancer: a case series\xa0

IntroductionEctopic breast tissue is present in 2–6% of women. Ectopic breast cancer represents an uncommon disease accounting for about 0.3% of all breast neoplasms, limiting the available evidence. Thus, we aim to report long-term outcomes in five cases treated at our institution.Case seriesOur Tunisian patients’ median age was 48 years (33–60 years), and the median follow-up was 8 years (4–10 years). The ectopic breast tissue was located four times in the right axilla. The median tumor size was 25 mm (15–55 mm). Four of the patients underwent a wide local excision and axillary lymph node dissection. Three of those women had positive lymph nodes; thus, they received adjuvant chemotherapy, radiation therapy, and hormone therapy. The patient with a negative lymph node (case 5) had adjuvant radiation therapy and hormonal therapy. One of the patients (case 1) had a positive supraclavicular lymph node and received radiation therapy, chemotherapy, and hormonal therapy. The latter developed a locoregional relapse after 4 years and was treated with mastectomy and chemotherapy. One patient (case 4) had a distant metastasis after 2 years of follow-up and received chemotherapy. The three other patients were free of relapse during their follow-up period.ConclusionPrimary axillary breast carcinoma is a rare entity. Despite the paucity of literature, our findings and authors’ recommendations suggest that local excision can be performed safely with promising outcomes in this subset of patients.

Axillary Mass Turned Out to be A Phyllodes Tumour in An Ectopic Breast Tissue– A Rare Case Report

Background: Phyllodes tumours are rare fibroepithelial lesions that account for less than 1% of all breast neoplasm. However, phyllodes tumours arising from ectopic breast tissue are even rarer, with less than 15 cases ever reported involving the axilla, vulva and groin. Case Presentation: A 27-year-old lady presented to the surgical clinic with left axillary swelling, measuring 5cm x 6cm. Ultrasound of the axilla revealed heterogenous mass displacing the left axillary artery and vein medially. Excision was performed, and histopathological examination confirmed the diagnosis of a benign phyllodes tumour. Conclusion: Phyllodes tumour in ectopic breast tissue over the axilla is a rare occurrence, and our case is the fourth case ever reported. Despite its rarity, diagnosis and treatment modalities are similar to phyllodes tumour of the breast. Regular follow-up is recommended owing to the risk of local recurrence.

Gynaecomastia-like hyperplasia of axillary ectopic breast tissue – a case report

Aim: To highlight the incidental finding of gynaecomastia-like hyperplasia of axillary ectopic breast tissue in a female patient, with review of the literature. Case report: A 36 year old multiparous female presented for surgical management of right axillary ectopic breast tissue on a background history of a previously excised right lower quadrant breast lesion one year prior that showed a 29mm grade 3 invasive breast carcinoma of no special type with triple negative immunophenotype. The sentinel nodes were uninvolved and excision margins were clear. She underwent neoadjuvant chemotherapy and local radiotherapy. There was no radiological or clinical evidence of recurrence at the one year mark. Excised axillary fibroadipose tissue histologically showed benign breast ducts without lobules demonstrating occasional micropapillary hyperplasia, as well as stromal pseudoangiomatous stromal hyperplasia (PASH). There was no evidence of in-situ or invasive malignancy. The overall appearance was that of gynaecomastia-like hyperplasia. Discussion: Gynaecomastia-like hyperplasia is a rare finding in breast specimens in female patients. It is exceedingly rare in ectopic breast tissue, with only a single case report in the literature to date. The spectrum of histologic changes are characteristic, although the pathogenesis is poorly understood due to the rare nature of this process.

Primary ectopic breast carcinoma in the axilla: A rare presentation and review of the literature

Ectopic breast tissue (EBT) develops as the result of the incomplete embryologic regression of the mammary ridge, which extends bilaterally from the anterior axilla folds to the inguinal folds in the fifth and sixth weeks of gestation. EBT is encountered in 0.3%-6% of women and 1%-3% of men and can be found anywhere along the milk line. It is subject to the same pathologic changes that affect the orthotopic breast. Primary carcinoma arising on the ectopic breast (PEBC) is a very rare occurrence accounting for 0.3%-0.6% of all breast cancers and is most frequently found in the axilla. Due to the rarity and atypical presentation of the disease, the diagnosis is often delayed. We herein present a very rare case of PEBC in the axilla along with a review of the literature. Any subcutaneous hypoechoic nodule located along the milk line without evidence of inflammation should raise concern for ectopic breast carcinoma. Accurate staging and differential diagnosis with detailed immunohistochemical analysis are required. No specific guidelines on diagnosis and treatment are available and the tumor is treated similarly to the orthotopic breast cancer of a similar stage. Physicians should be aware of this rare entity to avoid treatment delays.

The Role of Dexamethasone in the Era of “Dex-CSDH” Randomized Controlled Trial. A Multicenter, Prospective Study on Specific Subset of Patients with Chronic Subdural Hematoma (CSDH) Treated with Dexamethasone Alone or Surgery

Accessory or ectopic breast tissue is residual breast tissue that persists after normal embryonic mammary development. It can occur anywhere along the embryonic mammary streak, but is most commonly located in the axilla. Accessory breast tissue can consist of any component of the breast and may be functional or non-functional and its development is hormone dependent like normal breasts. Overall, the prevalence of accessory breast tissue in women ranges from 0.4% to 6%, and in men, from 1% to 3% [1]. Usually they are asymptomatic and do not need any intervention unless they start causing discomfort. Diagnosis of accessory breast tissue is important because they are subject to all diseases of the breast including carcinomas [2]. Here we report a case of asymptomatic accessory breast tissue in bilateral chest wall of a 32-year Nepalese multi Para female patient
