Multiple giant intra abdominal lipomas: A rare presentation

Intermuscular Fibrolipoma of the Neck: A Rare Case Report

Lipomas are slow growing tumors rarely found in children. We report a very rare case of an intermuscular fibrolipoma found deep within the posterior triangle of the neck. A 3 year old child was brought with the complaints of right sided neck mass and an inability to fully turn his head for two months. Ultrasound and computed tomography of the neck suggested a diagnosis of intermuscular lipoma. The patient was successfully managed by complete surgical resection of the mass. Histopathological examination confirmed the diagnosis as intermuscular fibrolipoma. Due to the rarity of the case, we are prompted to report it.

Giant Mesenteric Lipoma in an Adult

Lipomas are benign mesenchymal tumors of mature adipocytes and commonly occur in the upper trunk. Mesenteric lipomas are relatively rare tumors of the gastrointestinal system. They are usually asymptomatic, detected incidentally on abdominal imaging, or can present with variable symptoms depending on the location, size, and rapidity of tumor growth. The ileal mesentery is the most common site, occurring in adults ranging from 40 to 60 years. We present the case of an unusually large mesenteric lipoma in an adult male patient who presented with vague abdominal pain.

Giant Adult Mesenteric Lipoma: A Rare Cause of Chronic Abdominal Distention and Discomfort

Solitary or multiple lipomas are considered common tumors that can occur anywhere in the body; however, mesenteric lipoma is a rare entity that is well known to present with signs and symptoms of small bowel volvulus. Hereby, we present a case of a 54-year-old male patient with multiple comorbidities who was suffering from chronic abdominal discomfort and gradual increase of his abdominal distention over many years without seeking any medical attention. The patient was seen by a general practitioner after complaining of an inflated abdomen, as he described his condition. After several imaging studies, he was diagnosed with one of the largest mesenteric lipomas in the literature. Mesenteric lipoma should be present in the differential diagnosis of any abdominal tumor. Magnetic resonance imaging plays a major role in differentiating benign from malignant lipomas.

A giant lipoma of the parietal peritoneum: Laparoscopic excision with the parietal peritoneum preserving procedure - a case report with literature review

BACKGROUND

Lipomas are very common benign tumors of mature fatty tissue that can occur in any part of the body. However, lipomas of the parietal peritoneum are extremely rare.

CASE PRESENTATION

A 36-year-old man presented with urinary frequency for 6 months. On computerized tomography of the abdomen and pelvis, a well-defined fatty mass measuring 20 × 11 × 6.5 cm in size, was found in the lower abdominal cavity. We performed a laparoscopic parietal-peritoneum-preserving excision of the mass. The patient was discharged without complications on post-operative day 6.

CONCLUSIONS

To our knowledge, a laparoscopic excision with preservation of the parietal peritoneum for a giant parietal peritoneal lipoma has never been reported. Herein, we report a case of a giant lipoma of the parietal peritoneum successfully managed by laparoscopy.

Intra-abdominal fat. Part III. Neoplasms lesions of the adipose tissue

This article focuses on various cancerous lesions that are found beyond organs in the intra-abdominal fat and can be visualized with ultrasonography. These lesions are divided into five groups. The first group includes primary benign tumors containing adipocytes, such as lipoma, lipoblastoma, hibernoma and other lesions with an adipose tissue component, such as myolipoma, angiomyolipoma, myelolipoma and teratoma. The second group comprises primary malignant adipocytecontaining tumors, including liposarcoma and immature teratoma. The third group contains primary benign tumors without an adipocyte component that are located in intra-abdominal fat. This is a numerous group of lesions represented by cystic and solid tumors. The fourth group encompasses primary malignant tumors without an adipocyte component that are located in intra-abdominal fat. These are rare lesions associated mainly with sarcomas: fibrosarcoma, malignant fibrous histiocytoma, hemangiopericytoma and leiomyosarcoma. An epithelioid tumor at this site is mesothelioma. The last but not least group includes secondary malignant tumors without an adipocyte component located in intra-abdominal fat. This is the most numerous group with prevailing carcinoma foci. For each of these groups, the authors present ultrasound features of individual lesions and discuss their differential diagnosis. In the vast majority of cases, the material for cytological and histological analysis can be obtained during ultrasound-guided procedures. This is the advantage of this imaging modality.

Approach and management of a giant lipoma in the left lumbar region

•

We present a case of giant lipoma in the left lumbar region.

•

Movements were hindered, especially rotation, flexion and extension of the trunk.

•

The size of the bulk presents differential diagnostic problems with liposarcoma.

•

Surgical excision was performed to confirm diagnosis with histological evaluation.

Introduction

Lipomas are the most common benign tumors of the adipose tissue and can be located in any region of the body. In most cases lipomas are small and asymptomatic, but they can at times reach considerable dimensions and, depending on their anatomic site, hinder movements, get inflamed, cause lymphedema, pain and/or a compression syndrome.

Presentation of case

We here report the case of an otherwise healthy patient who came to our observation with a giant bulk in the left lumbar region which had been showing progressive growth in the previous 5–6 years. Physical examination, ultrasound and MRI were carried out in order to characterize the size, vascularization and limits of the lesion. Due to the pain and restriction of movement that this bulky lesion caused, surgical excision of the lesion was performed.

Discussion

Giant lipomas display an important differential diagnosis problem with malignant neoplasms, especially liposarcomas, with which they share many features; often the final diagnosis rests on histological evaluation. We here discuss the diagnostic problems that arise with a giant lipoma and all the possible approaches concerning treatment of such a big lesion, explaining the reasons of our approach and management of a common tumor in our case presenting unusual dimensions and location.

Conclusion

Our approach revealed to be successful in order to nurse our patient's pain, restore the mobility and address the aesthetic issues that this lesion caused. Postoperative checkups were carried out for one year and no signs of relapse have been reported.
