Giant Mesenteric Lipoma as a Rare Cause of Ileus in a Child: Report of a Case

Mesenteric lipoma is a rare benign tumor of mature fat cells. Although generally asymptomatic, it occasionally causes abdominal pain, ileus, and small bowel volvulus, depending on its location and size. A definitive diagnosis can be made by pathological examination. Ultrasonography and abdominal computed tomography show this lesion as a well-defined, homogeneous mass with fat density surrounded by a thin capsule. Because of its rare etiologic origin, we report the case of a 7-year-old girl with a mass in the abdomen and ileus, found to be caused by a mesenteric lipoma.     

Minilaparotomy Approach for Removal of a Large Colonic Lipoma: Report of Two Cases

A minimally invasive surgical approach should be employed to resect symptomatic colonic lipomas whenever possible. We report two cases of large colonic lipomas that were successfully removed using a minimally invasive minilaparotomy approach. Patient 1 was a 53-year-old man with a 3.8-cm symptomatic submucosal lipoma in the ascending colon and patient 2 was a 57-year-old woman with a 4.2-cm symptomatic submucosal lipoma in the transverse colon. Both lipomas were successfully removed through a 5–7-cm minilaparotomy. Normal bowel function returned quickly without any postoperative complications. These case reports demonstrate that the minilaparotomy approach is a suitable alternative to conventional laparotomy to remove a large colonic lipoma.     

Axillary Giant Lipoma: a Case Report

Lipoma are the most frequent mesenchymal soft tissue tumours but rarely present huge sizes in their cutaneous localization. Some cases of so-called “giant lipomas” have been reported in the literature and here is presented a giant lipoma of the axillary area which is, to our best knowledge, the second report of such a giant lipoma in this localization.     

A Large Intussuscepting Gastric Lipoma

Lipomas of the lower foregut are exceptionally rare. Presenting symptoms often include bleeding, weight loss, and obstructive symptoms. Surgical resection remains the standard treatment. We report a case of a large intussuscepting gastric lipoma.     

Giant Intrapericardial Extracavitary Lipoma: Report of a Case

Cardiac lipomas are very rare. We herein report a case of a 57-year-old woman who presented with intrapericardial extracavitary giant lipoma, and we also review the relevant literature. The patient had no symptoms except for a tendency to easily feel slightly fatigued. She underwent a resection of the lipoma through a clamshell thoracotomy. The lipoma weighed 1 700 g and had a cylindircal stalk measuring about 5 cm in diameter connected to the myocardium of the right ventricle.     

Lipoma of the stomach: Report of a case

Gastric lipomas are rare. Most of those that have been reported were found at necropsy. The usual site of growth is in the submucous layer of the stomach. As a rule they are symptomless unless complicated by inflammatory changes, ulceration, pyloric obstruction or bleeding. They may give rise to alarming hemorrhages, occult bleeding with secondary anemia, or pyloric obstruction.     

Case Report: A Gastric Lipoma in a Morbid Obese Man

We report a case of a 54-year-old, morbid obese man who presented with melena, hematemesis and fatigue over the last two days. The cause of this upper gastrointestinal bleeding was found on endoscopy which revealed an ulcerated submucosal mass in the gastric antrum. The haemorrhagia could not be stopped with injection of Aethoxysclerol. The mass was resected by an antrectomy with Roux-en-Y reconstruction.

Histologic examination showed a lipoma. No further treatment was necessary. In this case report, we would like to stress the need for histologic diagnosis to differentiate a benign gastric lesion from a malign.     

Laparoscopic Resection of an Ileal Lipoma: Report of a Case

A 63-year-old woman was admitted to our hospital for investigation of upper abdominal pain and vomiting. Ultrasonography (US) showed a hyperechoic mass in the right lower abdomen, and computed tomography (CT) showed a low-density mass and intestinal invagination. Thus, we made a diagnosis of intestinal lipoma with intussusception and performed laparoscopic partial resection of the ileum, including the tumor. The resected specimen contained a round tumor, 25 × 22 × 20 mm, which was identified as an intestinal lipoma histopathologically. Our experience supports earlier reports that US and CT are effective tools in the diagnosis of bowel lipoma. Laparoscopic surgery is the treatment of choice for benign tumors of the small intestine because it is minimally invasive, with cosmetic, physical, and economic benefits.     

Laparoscopic Management of a Large Duodenal Lipoma Presented as Gastric Outlet Obstruction

Lipoma of the duodenum is a rare tumor, with fewer than 230 cases reported to date. A majority of these tumors were managed by endoscopic and open surgical intervention, with published data on one case that was managed by total laparoscopy. We report a case of a 43-year-old woman with signs and symptoms of gastric outlet obstruction who was diagnosed as having a large duodenal lipoma that was managed successfully with laparoscopic excision.     

Pleomorphic Lipoma: Case Report and Literature Review

BACKGROUND: Pleomorphic lipoma is a rare, benign, pseudosarcomatous, soft tissue neoplasm typically involving the subcutis of the neck and shoulder in middle-aged to elderly men. It is characterized histologically by atypical, multinucleated giant cells and grossly as a well-circumscribed mass. Since this neoplasm can resemble a sarcoma, histopathologic diagnosis is critical in preventing unnecessary surgery. OBJECTIVE: To describe a case of pleomorphic lipoma in the neck and to review the clinical and histopathologic characteristics of this neoplasm. METHODS: We present a case report and review of the literature. RESULTS: Local excision to completely extirpate this neoplasm has proven curative at 10 months of follow-up. CONCLUSION: Pleomorphic lipoma is superficially located and may be encountered in a dermatologic setting. Thus the dermatologist should become familiar with its clinical presentation and microscopic appearance.     

Adult Intussusception Caused by a Lipoma in the Small Bowel: Report of a Case

Adult intussusception represents only about 5% of all intussusceptions and is usually caused by a malignant small bowel lesion acting as the apex of intussusception. We report an unusual case in a male patient of adult intussusception caused by a lipomatous lesion located in the terminal ileum, very close to the ileocecal valve, acting as the lead point. After repeated admissions to several hospitals for investigation of nonspecific abdominal symptoms, the possibility of intussusception was finally raised by a computed tomography (CT) scan of the abdomen. The patient underwent a limited right hemicolectomy, which achieved long-lasting cure of his symptoms. This case highlights the difficulties of diagnosing adult intussusception promptly, and the fact that it can also be caused by a benign lesion.     

Intraosseous Lipoma: A Report of Two Cases

Intraosseous lipoma seems to be a rare condition as only some 20 cases have been reported so far. A further two cases are described the lesions being in the calcaneus and in the tibia. Radiographically the lesions appeared osteolytic and well delineated, containing calcified areas. The microscopic features were those of mature adipose tissue. Curettage and packing with autogenous bone grafts is recommended, if the lesion causes pain or a correct diagnosis cannot otherwise be obtained.     

Endobronchial Lipoma Accompanied with Primary Lung Cancer: Report of a Case

A 72-year-old man was found to have an endobronchial lipoma accompanied with primary lung cancer. A left lower lobectomy with a mediastinal lymph node dissection and a sleeve resection of the lingual bronchus with telescoping bronchial anastomosis were done. The pathological staging was T1N2M0, stage IIIA. A histological examination showed well-differentiated squamous cell carcinoma in segment 10, in addition to the presence of mature adipose tissue which was diagnosed to be a benign endobronchial lipoma originating from the lingual bronchus. The postoperative course was uneventful and the patient was discharged 13 days after the operation. However, he had a recurrence in the subcarinal lymph node, and died 8 months after surgery.

A Small Bowel Volvulus Caused by a Mesenteric Lipoma: Report of a Case

A 31-year-old man underwent a laparotomy for acute intestinal obstruction symptoms, which he had intermittently experienced for 14 years. The cause of the obstruction was due to a volvulus of the small bowel caused by a mesenteric lipoma. This is a rare finding, which is ideally diagnosed by computed tomography, with surgery the best and most highly recommended treatment. This particular presentation, to the best of our knowledge, has not yet been previously reported in the English language.     

Strangulated Umbilical Hernia in a Child: Report of a Case

Most umbilical hernias in children close spontaneously. Complications associated with umbilical hernias are rarely observed during follow-up. We report herein a 5-month-old girl with a strangulated umbilical hernia. Her umbilicus was hard, reddish, and irreducible. Plain radiography of the abdomen showed signs of mechanical ileus. The patient was thus diagnosed to have a strangulated umbilical hernia. A 5-cm section of the ascending colon and a 5-cm section of the terminal ileum, as well as the cecum and appendix, were congested, edematous, and erythematous, and together were enclosed by a firm hernial ring. A closure of the fascial defect and umbilicoplasty were performed. The postoperative course was uneventful. In patients with infantile umbilical hernias, strangulation may occur as the fascial defect decreases in size. Received: May 30, 2000 / Accepted: January 9, 2001     

Intraneural Lipoma of the Tibial Nerve: A Case Report

Intraneural lipomas, neurofibrolipomas, lipofibromatous hamartomas, and perineural lipomas are subsets of hamartomas that typically present as fibroadipose, soft tissue masses within the epineurium of a nerve. Several cases involving intraneural lipomas of the median nerve in the upper extremity have been reported; however, owing to the lesion's rare incidence in the foot and ankle, only a select few cases involving the superficial peroneal nerve have been reported. We present the first case of a tibial nerve intraneural lipoma in a 42-year-old female with a follow-up period of 2 years. We discuss the clinical presentation, distinguishing features, surgical procedures, and short-term outcome regarding this unique tumor.
