Lipoma-like hibernoma: an atypical lipoma/well-differentiated liposarcoma mimicker

Giant gastric lipoma mimicking well-differentiated liposarcoma

Authors report the case of a 51-year-old man, presenting with epigastralgia of recent onset. Physical exam was unremarkable. Endoscopy revealed a large, ulcerated, submucosal, antral tumor. CT scan reveals an antral mass with fat attenuation. The patient underwent a total gastrectomy. Macroscopic examination identified in the antral wall a 9-cm, well-circumscribed, nodular lesion, with a yellow...

Well-differentiated liposarcoma associated with benign lipoma.

The objective of this study was to review the clinicopathological features of seven patients presenting with well-differentiated liposarcoma (WDL), which was associated with subcutaneous lipoma. From 1980 through 2002, 34 individuals displaying WDL were treated in our institutions. Lipoma was observed in seven of these 34 patients (five men and two women, mean age of 66.7 years). The rate of co...

Hibernoma (granular cell lipoma).

Deep-seated huge hibernoma of soft tissue: a rare differential diagnosis of atypical lipomatous tumor/well differentiated liposarcoma.

BACKGROUND Hibernoma is a rare benign fat-forming soft tissue tumor that differentiates similar to brown fat, hence an origin from remnants of fetal brown adipose tissue has been proposed. Mainly young adults are affected, usually without significant clinical symptoms. MATERIAL AND METHODS We report on four patients with hibernomas, who were treated at our hospital during the last 10 years. T...
