ABSTRACT
BACKGROUND: Angiosarcoma is a rare high-grade neoplasm that frequently involves the skin and subcutaneous tissue. Rarely, angiosarcoma can occur in the gastrointestinal tract where it frequently exhibits multicentric epithelioid morphology. DESIGN: We report a case of multicentric epithelioid angiosarcoma (EAS) of the small intestine in a 73-year-old male patient who presented with weakness and melena, and was found to have bleeding lesions in the small intestine on upper gastrointestinal endoscopy. In addition to this case, we extensively reviewed the clinical and pathological features of previously reported cases of angiosarcoma of the small intestine in the English literature since 1970. RESULTS: Our patient presented with rare and aggressive EAS of the small intestine. Despite surgical resection of the lesions, the patient continued to worsen and developed rapidly progressive metastatic disease. He died within 4 months of the diagnosis. CONCLUSIONS: Angiosarcoma, especially of the deep tissues and the gastrointestinal tract, is very aggressive and rapidly metastatic. The survival rate in these patients is extremely poor, and most patients die within 6 months to 1 year of the diagnosis. Treatment usually involves surgical resection of the bleeding lesions and frequent blood transfusions for symptom alleviation.
