Case report: gastric angiolipoma with chronic hemorrhage and severe anemia.

Lipomas are benign tumors that are common in other sites but rare in the stomach. They are usually submucosal and, when symptomatic, are most often accompanied by gastrointestinal hemorrhage. Angiolipoma is a not uncommon benign lipomatous neoplasm with a characteristic vascular component that almost exclusively occurs in the subcutaneous tissue. A case of gastrointestinal angiolipoma, which appears to be only the second one reported, is discussed. The patient, a 69-year-old man, presented with signs and symptoms of chronic hemorrhage and severe anemia (hemoglobin 6, hematocrit 19.9). The patient's condition was found to have resulted from ulceration of the gastric mucosa overlying a submucosal angiolipoma, and the anemia resolved after local surgical resection of the tumor. Electron microscopic studies supported the light microscopic diagnosis of angiolipoma. The absence of fibrin thrombi in this and other nonsubcutaneous angiolipomas and the possible significance of the vascularity of these tumors is discussed. The literature regarding gastric lipoma and angiolipoma is reviewed.
