One type of soft tissue lesions of the oral cavity is lipoma, which is a kind of benign tumor composed of mature lipid cells. Although the lipoma presents as one of the most common mesenchymal neoplasms, most tend to develop on the trunk and proximal portions of the extremities. However, lipomas in the oral and maxillofacial region are much less frequent. Here we present a case of an intraoral lipoma in a six year-old child.

Lipomas are the most common benign tumors of soft tissues. However, conventional lipomas have been reported only rarely as presenting in the vulva. We present a case of vulvar lipoma in a 17-yr-old woman, possibly caused by chronic intermittent irritation.

Lipomas are common benign tumors of mature adipose tissue, enclosed by thin fibrous capsules. They can occur on any part of the body; however, peritoneal lipoma is extremely rare. We encountered a case of a 75-year-old man presenting with intermittent abdominal pain, who had undergone right hemicolectomy due to colon cancer. Abdominal computerized tomography showed a well-defined heterogenous fatty mass measuring 4.5x3.5 cm in size, suggesting fat necrosis located in the abdominal wall. Laparotomy showed a very large soft mass of peritoneum. Pathologically, the tumor was diagnosed as lipoma containing fat necrosis located in parietal peritoneum not fixed to any organs, but with small bowel adhesion. Due to its rare etiologic origin and obscure cause of development, we report on a case of lipoma of parietal peritoneum causing abdominal pain.

A 58-year-old Chinese woman presented with deranged liver function tests, which was discovered incidentally during surveillance for statins therapy. Ultrasonography and computed tomography revealed a large lipoma originating from the greater omentum, which was treated with surgical resection. This case is reported due to the rare occurrence of omental lipomas.

We report a rare case of giant mesenteric lipoma presenting with colicky abdominal pain. A 29-yr-old woman underwent laparoscopic resection for a giant mesenteric lipoma causing compression of the ileal loop. The resected ileal segment was encased by a giant fatty tissue, and normal mucosal fold patterns of the resected ileum were effaced by the mass. Microscopically, the mass was characterized by homogenous mature adipose tissue without cellular atypia, which was compatible with the diagnosis of a mesenteric lipoma. Despite the benign nature of this tumor, total excision with or without the affected intestinal loop should be considered if intestinal symptoms such as abdominal pain are present.
