Method: This study involved (85) women within reproductive age (25-40) years, who were distributed into two groups: patientsʹ group (55) women diagnosed with endometriosis, and (30) healthy control women. The study was carried out at Al-Karkh Maternity Hospital/ Baghdad and extended from 20/4/2024 to 20/5/2024. The pathological cases of patients were diagnosed by clinical examinations and confirmed by specialist physician with ultrasound examination. Blood samples were taken from both groups, serum was separated for each individual by a centrifuge. Results: a significant rise in the (FSH, Leptin, TNF -α, Adipisin) while a significant decrease in levels of (Testosterone , LH, GST, TAC, Ghrelin) concentration were found in the sera of patients compered to healthy women , with a probability of P ≤ 0.05. According to Receiver operating characteristic (ROC) statistical analysis, Area under curve (AUC ) for LH, leptin, TNF -α, adipsin, ghrelin, GST, TAC were closely or equal to (1) for patients . Conclusion: serum levels of LH, Leptin, Adipisin, Gherlin, TNF-α and GST can be dependable as prognostic indicator markers that reflect the degree of oxidative stress accompanying endometriosis.

Intramuscular lipomas posing diagnostic and pre-operative counselling challenges in a low-resource setting: A case series

IntroductionIntramuscular lipomas (IMLs) are uncommon primary adipose tissue tumours deep within the muscle. A high likelihood of misdiagnosing them as other benign and malignant masses necessitates imaging studies to confirm the diagnosis and plan treatment. Ultrasonography is useful but CT and MRI provide a more accurate diagnosis. While diagnostic tests are suitable, they may not always be accessible or affordable in low-resource settings. We present three cases of IMLs that emphasise the difficulties posed by limited resources and the significance of a comprehensive medical history and physical examination in low-resource settings. Presentation of casesThe patients included a 57-year-old male with a distal right thigh mass, a 65-year-old female with a proximal right thigh mass, and a 60-year-old female with a mass at the left scapular area. The three patients underwent surgical excision and had an uneventful postoperative course, with no reported recurrence during their ongoing follow-up. DiscussionThe management of IMLs is not complicated if the requisite resources are available. Conversely, in low-resource settings with limited diagnostic facilities and human expertise, management may take a challenging path. Patient 1, despite undergoing diagnostic tests confirming IML, initially declined treatment due to challenges with pre-operative counselling. Patients 2 and 3 lacked health insurance and could not afford diagnostic imaging tests. ConclusionHealthcare professionals in low-resource settings should familiarise themselves with the clinical characteristics and pathology of IMLs to minimise misdiagnosis and ensure appropriate counselling is provided to patients. IMLs are slow-growing mostly asymptomatic benign swelling. On physical examination, they are usually non-tender, soft, masses, not fixed to the bed or overlying tissue. The overlying skin is normal and lymphadenopathy is absent.

A Novel Approach for Treating Lipomas: Percutaneous Microwave Ablation Combined with Liposuction.

Lipomas, benign adipose tissue tumors, are a common occurrence but currently, the options for their treatment are limited, with surgical excision being the most frequently used management pathway. This scenario can often lead to unsatisfactory cosmetic results and significant patient discomfort. This paper introduces a novel technique, percutaneous microwave ablation with liposuction, to address these challenges. The innovative procedure aims to enhance patient satisfaction, minimize post-operative discomfort, and improve aesthetic outcomes. The technique involves two key steps: (1) the application of percutaneous microwave ablation to selectively disrupt the lipoma cells, followed by (2) a targeted liposuction procedure to remove the ablated lipoma tissue. Our approach optimizes the removal of the lipoma and preserves the surrounding healthy tissue, reducing the risk of local recurrence and improving the cosmetic result. The use of preoperative ultrasound imaging allows for precise localization and delineation of the lipoma, aiding in the planning and execution of the procedure. This novel approach to lipoma treatment is reliable, associated with minimal morbidity, and consistently yields effective results. Additionally, it provides a new perspective on lipoma management, potentially changing the paradigm of current treatment approaches.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

Abstract 3405: CT-assessed body composition and tumor immunologic characteristics in patients with non-small-cell lung cancer

Abstract Objectives: Obesity is associated with higher immunotherapy efficacy, but body mass index is a convoluted marker of adipose and muscle tissue. We conducted a discovery scale study to assess the association of skeletal muscle and adipose tissue areas annotated on computed tomography (CT) scan images with selected tumor immunologic characteristics among patients with non-small-cell lung cancer (NSCLC). Methods: We analyzed publicly available data from 102 patients (mean age = 67.2, 47.1% female, and 70.6% stage I-II) who had diagnostic CT images in The Cancer Image Archive. All patients had the 12th thoracic vertebra (T12) image, and a subset (62 patients) had the 3rd lumber vertebra (L3) image. Paravertebral muscle areas on T12 and skeletal muscle and adipose tissue areas on L3 were annotated using Slice-O-Matic. RNA-seq data were provided by The Cancer Genome Atlas and Clinical Proteomic Tumor Analysis Consortium; percentages of CD8, regulatory T cells, and activated NK cells were identified using the CIBERSORT. ESTIMATE algorithm was used to derive the stromal score and the immune score. Differences in the immune markers were examined using ANOVA adjusting for stage, histology, and study. Results and Conclusion: Patients with higher paravertebral muscle area (3rd tertile) had the lowest stromal scores, compared to the 2nd and 1st tertile (P<0.05). Patients in the 2nd tertile of paravertebral muscle areas had the highest immune score and CD274 (PD-L1) gene expression. Among the body composition types classified using L3 images, low muscle/high adiposity was associated with lower stromal scores, and low muscle was associated with lower immune scores, compared to high adiposity and high muscle/low adiposity types. Other immunological markers did not differ across the body composition types. Significance: These findings suggest associations between deconvoluted skeletal and adipose tissue components and tumor markers relevant to immune checkpoint inhibitor efficacies in NSCLC. Further validation using immune phenotyping in a large patient sample is warranted. Funding: The study is in part supported by NIH/NCI R37CA248371 and OSU Comprehensive Cancer Center - James.

Imaging diagnosis: CT characteristics of a retrobulbar hibernoma in a dog.

A 12-year-old female spayed Beagle was referred for investigation of exophthalmos. CT revealed a well-defined, retrobulbar mass causing rostro-dorsal displacement of the left globe. The mass had a mildly heterogeneous precontrast soft tissue attenuation with mild heterogeneous enhancement following iohexol administration. The mass was surgically removed en bloc with an orbital exenteration. Histopathology confirmed the mass to be a hibernoma, a benign tumor of brown adipose tissue. Hibernomas have CT characteristics consistent with both benign and malignant adipose tumors and may be underrecognized by radiologists.

A case of Wilson’s disease combined with intracranial lipoma and dysplasia of the corpus callosum with review of the literature

BackgroundWilson’s disease (WD) is an inherited disorder of copper metabolism. Agenesis of the corpus callosum is the complete or partial absence of the major united fiber bundles connecting the cerebral hemispheres. Intracranial lipoma is an adipose tissue tumor resulting from an abnormal embryonic development of the central nervous system. The simultaneous occurrence of these three disorders is rare and has not been reported. This report focuses on the pathogenesis and association between the three disorders and highlights the importance of recognizing and effectively managing their coexistence.Case presentationThe purpose of this study was to present a patient with coexisting WD, intracranial lipoma, and corpus callosum dysplasia. We reviewed a female patient hospitalized in 2023 with clinical manifestations of elevated aminotransferases and decreased ceruloplasmin, as well as genetic testing for an initial diagnosis of Wilson’s disease. Subsequently, a cranial MRI showed corpus callosum dysplasia with short T1 signal changes in the cerebral falx, leading to a final diagnosis of Wilson’s disease combined with intracranial lipoma and corpus callosum dysplasia. The patient’s WD is currently stable after treatment with sodium dimercaptosulfonamide (DMPS) and penicillamine, and the patient’s abnormal copper metabolism may promote the growth of intracranial lipoma.ConclusionThe pathogenesis of WD combined with intracranial lipoma and corpus callosum dysplasia is complex and clinically rare. The growth of intracranial lipomas may be associated with abnormal copper metabolism in WD. Abnormal copper metabolism affects lipid metabolism and triggers inflammatory responses. Therefore, early diagnosis and treatment are beneficial for improvement. Each new case of this rare co-morbidity is important as it allows for a better assessment and understanding of these cases’ more characteristic clinical manifestations, which can help estimate the course of the disease and possible therapeutic options.

Symptomatic Preperitoneal Lipoma Resected via Preperitoneal Approach: A Case Report and Review of the Literature

Introduction: Lipomas are benign adipose tissue tumors that can vary in size and location. Magnetic resonance images should be obtained for all soft-tissue masses that are deep to fascia or those >5 cm in subcutaneous tissue. In this case report, we present a minimal invasive technique to resect a large preperitoneal lipoma. Case Presentation: A 36-year-old woman presenting with left fossa pain caused by a large mass. MRI-imaging shows a large preperitoneal lipomatous lesion (61 × 58 × 40 mm) which compresses the bladder, tuba and surrounding vessels. We did a minimally invasive preperitoneal laparoscopic surgical resection. Postoperative follow-up was uneventful. The pathology report confirmed benign lipoma without signs of malignancy. Discussion: Preperitoneal lipomas should be considered in the diagnosis of lower abdominal pain and can be minimally invasive resected via preperitoneal laparoscopic approach in day clinic.

A case of a rare hibernoma tumour and a brief literature review

Hibernomas refer to benign tumours of immature adipose tissue known a brown fat. They are most commonly found in areas where brown adipose tissue is still present in adulthood such as the shoulder, back, neck, best, arm and abdomen. This case study describes a 60 year old male who presented with a growing 15 mm lump in the right forearm. On examination, tenderness in the area surrounding the mass was elicited. A magnetic resonance image of the right forearm was performed which reported a large intramuscular lipomatous tumour within the brachioradialis muscle, in close relation to the neuromuscular bundle. Surgical excision was performed successfully. Histology was consistent with a diagnosis of a hibernoma tumour. The patient healed well with no evidence of infection or recurrence on follow up.

MDM2 FISH testing criteria in adipose tissue tumors with mature adipocytic morphology-A resection case-based study

The current criteria for utilizing MDM2 Fluorescence In Situ Hybridization (FISH) in adipose-derived tumors were first introduced in 2015 and have been widely adopted. However, these criteria may fail to identify some atypical lipomatous tumors / well-differentiated liposarcoma (ALT/WDL) with mature adipocytic morphology in clinical practice, possibly due to the fact that the existing criteria are primarily based on biopsy cases. Hence, a criterion based on resection cases is needed. In this study, we included 87 adipose tissue tumors with mature adipocytic morphology which were first resected, as well as 9 consultation cases and 25 recurrent resection cases. The final diagnosis was based on MDM2 amplification status. Among the 87 first-time resection cohort, MDM2 FISH amplification was observed in only 2 (5%) of the 39 superficial cases. Marginal infiltration was significantly different in both the MDM2 FISH negative and positive groups (p<0.05). Of the 37 intramuscular tumors, 17 (46%) showed MDM2 FISH amplification. The MDM2 amplification positive group had a larger tumor size than MDM2 amplification negative group (p=0.042). Tumors of larger size (≥11cm) were highly correlated with MDM2 amplification (p=0.003), but still, 35.3% of the MDM2 amplification-positive cases had tumor sizes less than 11cm. Eight (66.7%) out of twelve retroperitoneal/ pelvic cases were MDM2 FISH positive. Among the 25 recurrent cases, twenty (80%) of them had MDM2 FISH amplification. In conclusion, we recommend MDM2 FISH for: 1. superficial cases with marginal infiltration based on adequate margin sampling; 2. all intramuscular tumors, retroperitoneal/pelvic tumors and recurrent tumors, both in resection cases and biopsy cases.

How We Do It: Narrow Hole Extrusion Technique for Lipoma Removal

Subcutaneous lipomas are benign, slow-growing tumors of adipose tissue. The goal of removal is to achieve complete extirpation with optimal cosmesis. Given the inherent features of these subcutaneous lesions, complete extirpation can consistently be achieved through very small incisions, a technique known as narrow hole extrusion technique.

INTRAORAL FIBROLIPOMA – AN UNUSUAL PRESENTATION

Lipomas are most common tumours of mesenchymal origin in human body but are rare in oral and maxillofacial regions. They arise from the mature adipose tissues. The aetiology and pathophysiology remain ununderstood. Various theories have been proposed to explain the pathogenesis of this adipose tissue tumour. A case of intraoral brolipoma occurring in vestibular region in a 50-year-old female is reported. Excision was performed under local anaesthesia and one-year follow-up showed excellent healing with no signs of recurrence. Various histological patterns of lipoma have been explained in literature. Most of them are asymptomatic, resulting in delay to seek treatment.

ЛИПОМА КАК СЛУЧАЙНАЯ НАХОДКА В АБДОМИНАЛЬНОЙ ХИРУРГИИ

Primary neoplasms of the abdominal cavity are rare and usually have a mesenchymal origin. Lipoma is a benign mature tumor of adipose tissue, it occurs more often in women aged 30 to 50 years. Retroperitoneal lipoma is a rare variant of lipoma, manifested by various signs and symptoms that can mislead specialists. Lipomas are more common in abdominal surgery in the gastrointestinal tract. In this localization, the main pathognomonic complication is intestinal intussusception. Diagnosis is difficult, due to the relatively slow growth of education, characteristic clinical manifestations may be absent for a long time. X-ray imaging is the preferred diagnostic method. To date, surgical resection is the priority method of treatment of this pathology. The analysis of scientific literature on the occurrence of abdominal lipomas is carried out. The diagnostic significance in assessing the condition and complications of lipomas has been studied. Clinical cases from personal practice on the basis of the State Clinical Hospital named after him are presented. Yudina. Patients with diagnoses of giant retroperitoneal lipoma and complicated small intestine lipoma by female intussusception aged 62 and 78 years, respectively. The first clinical case demonstrates the randomness of the determination of lipoma in a patient admitted to the clinic with a closed craniocerebral injury and a wound of the soft tissues of the head. Ultrasound of the abdominal cavity showed the presence of a large retroperitoneal formation of an inhomogeneous consistency. During laparotomy, a giant fatty tumor with clear boundaries was revealed, closely adjacent to the adipose tissue of the retroperitoneal space. Lipoma was removed, drainage of the abdominal cavity and retroperitoneal space was performed. Histopathological examination confirmed the diagnosis of retroperitoneal lipoma. The weight of the lipoma was 10.610 kg. The postoperative period proceeded without complications. The second clinical case shows how a long-term undiagnosed lipoma of the gastrointestinal tract leads to a complicated course, namely intussusception. Patient A. 78 years old with discomfort and abdominal pain during the last few weeks, small intestine invagination was detected using ultrasound. Diagnosis upon admission: acute pancreatitis. A resection of the altered section of the small intestine was performed. The postoperative period was favorable. The patient was discharged on the 10th day. The presented clinical cases of this disease once again confirm the importance of timely dispensary diagnosis of abdominal tumors.

Large soft-tissue mass in the extremity is not necessarily a sarcoma: A case report of a giant lipoma of the thigh

Lipoma is the most common benign adipose tissue tumor. Giant lipomas are those that measure more than 10 cm in length or more than 1000 g in weight. There is a possibility of sarcomatous change in them but it is not always the rule. Lipoma and liposarcoma can be differentiated on the magnetic resonance imaging features of tumor size, stranding, nodularity, T2 signal, and contrast enhancement. The existence of thin septa helps identify lipomas and distinguishes them from well-differentiated liposarcomas, which have thick and irregular septa and fat necrosis at times. The open surgical approach is the best for the complete excision of giant lipomas without any recurrence.

Protective effect of rosmarinic acid-rich extract from Trichodesma khasianum Clarke against microbiota dysbiosis in high-fat diet-fed obese mice

Hypertrophy of adipose tissues and dysbiosis are hallmarks of obesity. Although drugs are applied for obesity treatment, side effects limit their use. The anti-obesity capacity of rosmarinic acid (RA) has been documented. Trichodesma khasianum Clarke is an edible RA-rich plant grown in Taiwan. Our previous study found that an 80 % ethanol extract of T. khasianum Clarke leaves (80EETC) ameliorates gastric mucosal damage through its anti-inflammatory, antioxidant, and microbiota modulation abilities. However, the anti-obesity effect of 80EETC remains unclear. Therefore, the objective of this study was to explore the protective effects of low-dose 80EETC (125 mg/kg b.w., 80EETCL) or high-dose 80EETC (250 mg/kg b.w., 80EETCH) on obesity development through gut microbiota modulation in high-fat diet (HFD)-induced C57BL/6 mice. The results showed a high RA content (89.2 ± 7.4 mg/g) in 80EETC. 80EETC administration significantly decreased body weight, body fat ratio, serum lipid levels (TC, TG, and LDL-C), adipose tissue accumulation, malondialdehyde (MDA), and tumor necrosis factor-α (TNF-α) in HFD-fed mice. Furthermore, supplementation with 80EETC reduced the Firmicutes/Bacteroidetes ratio and enhanced the relative abundance of gut microbiota (p_Bacteroidetes, f_Lactobacillus, f_Muribaculaceae, f_Prevotellaceae, g_Lactobacillus, g_Prevotellaceae_NK3B31_group, g_Ruminococcaceae_UCG–013, and g_Ruminococcaceae_UCG–014), which negatively correlated with obesity-related factors such as body weight, energy intake, fat accumulation in adipose tissue, TC, TG, LDL, and MDA. In conclusion, RA-rich 80EETC had a protective effect against obesity development and it has potential in healthy food applications.

Comparative Study of Outcome of Wedge Excision of Perforation Site and Trimming of Perforation Margin Followed by Primary Repair in the Management of Ileal Perforation

Lipomas are benign tumors of adipose tissue consisting of soft, lobulated masses held together with connective tissue and sometimes encapsulated in a thin, fibrous capsule. Lipomas are the most common soft tissue tumor, occurring in 1% of the population. The objective of our study is to present the epidemiological aspects of lipomas in the population of the region of Tangier-Tetouan-Al Hoceima, to determine the etiopathogenic aspects, and to describe the modalities of surgical treatment and especially to make a comparison between the lipectomy and liposuction. This study was carried out retrospectively, by collecting, the sex, and the reason for consultation and the location of the lipomas in the patients admitted to our service, over a period of 12 months from April 2021 to May 2022. The age of our patients ranged from 21 to 46 years. The mean age was 35 years and 3 months. We had 20 (74%) women and 7 (26%) men. The sex-ratio men/women were 0, 35. It must be said that many of our patients consulted because they had noticed an abnormal swelling on one part or another of their bodies. Regarding the management of our patients, only 5 benefited from liposuction while 22 patients benefited from a lipectomy. In all patients, the postoperative follow-up was simple with no early complications.

SUBMANDIBULAR LIPOMA EXCISION: A CASE REPORT

The aim of this study is to report the excision of a benign tumor of adipose tissue in the submandibular region. A 57-year-old dark-skinned male patient reported increased volume on the left side of his face, with approximately 10 years of evolution. The physical exam showed increased submandibular volume on the left side: a nodule measuring about 10 cm, with a soft and mobile consistency and painless. Fine needle aspiration puncture exam, contrast computed tomography, and ultrasound of the affected site were performed and the result was suggestive of benign tumor of adipose tissue. The patient underwent surgery by submandibular approach and excisional biopsy of the lesion was performed. The tumor presented a yellowish color, measuring 7 cm in its largest diameter. The material was sent for histopathologic examination, which confirmed the diagnosis of lipoma, a benign tumor of adipose tissue. Twelve months of follow-up showed no recurrence or complications.

Mesenteric lipoma with small bowel volvulus: A rare cause of upper gastrointestinal obstruction (a case report and literature review).

IntroductionSmall bowel volvulus due to mesenteric lipoma is a rare clinical entity. It poses both a diagnostic and therapeutic challenge. Small bowel mesenteric lipoma is a rare cause of small bowel obstruction. We present the case of a patient admitted to our emergency department for a small bowel volvulus due to a mesenteric lipoma with small intestine obstruction.Patient and methodA 61 years old man, with diabetes since 25 years with antidiabetics oral medication, vaccinated against Covid 19 (two doses) who presented with peri-umbilical pain for two months, constipation and melaena, complicated 3 days before his admission by obstructive symptoms and vomiting with apyrexia and overall health state alteration. The physical examination noticed abdomen distension and the abdominal CT scan revealed a large fatty mass of the hypochondrium and left flank, roughly oval with regular borders, well limited measuring 124 × 86 mm of height of 126 mm thought to be a liposarcoma. The patient underwent enbloc resection of 20 cm of small bowel with the mass and end to end anastomosis of the ileo-ileum. The postoperative course was uneventful and he was been discharged from hospital on day 5.DiscussionMesenteric lipomas are diagnosed incidentally after laparoscopy or laparatomy. Ultrasound shows a well defined homogenous echogenic mass, and so can distinguish it from a mesenteric cyst. Computed Tomography (CT) is the standard imaging of diagnosis and shows homogenous tumor of adipose tissue. The treatment is surgery and the prognosis is better.ConclusionThe mesenteric is an uncommon location of lipoma. When there is small bowel obstruction with intra-abdominal mass, the mesenteric lipoma could be recalled.

Sarcopenia, Precardial Adipose Tissue and High Tumor Volume as Outcome Predictors in Surgically Treated Pleural Mesothelioma.

Background: We evaluated the prognostic value of Sarcopenia, low precardial adipose-tissue (PAT), and high tumor-volume in the outcome of surgically-treated pleural mesothelioma (PM). Methods: From 2005 to 2020, consecutive surgically-treated PM-patients having a pre-operative computed tomography (CT) scan were retrospectively included. Sarcopenia was assessed by CT-based parameters measured at the level of the fifth thoracic vertebra (TH5) by excluding fatty-infiltration based on CT-attenuation. The findings were stratified for gender, and a threshold of the 33rd percentile was set to define sarcopenia. Additionally, tumor volume as well as PAT were measured. The findings were correlated with progression-free survival and long-term mortality. Results: Two-hundred-seventy-eight PM-patients (252 male; 70.2 ± 9 years) were included. The mean progression-free survival was 18.6 ± 12.2 months, and the mean survival time was 23.3 ± 24 months. Progression was associated with chronic obstructive pulmonary disease (COPD) (p = <0.001), tumor-stage (p = 0.001), and type of surgery (p = 0.026). Three-year mortality was associated with higher patient age (p = 0.005), presence of COPD (p < 0.001), higher tumor-stage (p = 0.015), and higher tumor-volume (p < 0.001). Kaplan-Meier statistics showed that sarcopenic patients have a higher three-year mortality (p = 0.002). While there was a negative correlation of progression-free survival and mortality with tumor volume (r = 0.281, p = 0.001 and r = −0.240, p < 0.001; respectively), a correlation with PAT could only be shown for epithelioid PM (p = 0.040). Conclusions: Sarcopenia as well as tumor volume are associated with long-term mortality in surgically treated PM-patients. Further, while there was a negative correlation of progression-free survival and mortality with tumor volume, a correlation with PAT could only be shown for epithelioid PM.

Fibrolipoma of Neck - A Case Report

Introduction: Lipoma is the most common benign mesenchymal tumor of adipose tissue. Their occurrence in the head and neck is relatively rare. Lipomas in the neck region are rare tumors that usually present as slowly growing painless masses, found in the lateral portions of the neck. Case Report: Here, we report a case of lipoma lying over the right nape of the neck in a 26-year-old female. A pedunculated overgrowth was gradually progressive in size with no other complaints. It was soft, mobile and non-tender. It was clinically diagnosed as a fibroepithelial polyp and later on, a histopathological examination was performed which revealed benign lipoma. Surgical excision is an elective treatment. However, an accurate differential diagnosis, postsurgical histological examination and careful follow-up are required. The purpose of this case report is to recognize rare lipomas that occur in unusual locations in the head and neck in order to identify them when they cause diagnostic problems. Conclusion: Lipomas can occur in any site of the body, However, rare variants in unusual sites should not be ignored by clinicians and should be sent for histopathological diagnosis for a confirmed diagnosis.
