ABSTRACT
BACKGROUND:
Epithelioid angiosarcoma is a vascular neoplasm that is among the most aggressive subtypes of sarcomas. Its involvement in the gastrointestinal tract is rare. We here report a case of multifocal gastrointestinal epithelioid angiosarcomas presenting with gastrointestinal bleeding. CASESUMMARY:
A 77-year-old woman was admitted because of melena and dizziness for three months. Gastroscopy and colonoscopy were performed, revealing a centrally ulcerated hemorrhagic polypoid lesion in the gastric body and multiple polypoid lesions with blood clots and hemorrhagic tendency in the colon. Histopathological examination of routine endoscopic biopsy samples showed inflammation in the gastric mucosa and tubular adenomas in the colon. The polypoid lesions were removed by endoscopic mucosal resection. Immunohistochemistry suggested a final diagnosis of epithelioid angiosarcomas. The patient refused chemotherapy and died after three months.CONCLUSION:
Epithelioid angiosarcomas are characterized by highly vascular nature and tendency to cause gastrointestinal bleeding. Efforts to obtain histological findings using endoscopic mucosal resection are of great importance.Palavras-chave
