Core Tip

Core tip: Gastrointestinal epithelioid angiosarcoma is extremely rare, which is only described in individual case reports and case series. Most reported cases appeared as centrally ulcerated, hemorrhagic, highly erythematous or purpuric nodules. Histopathology is the golden standard for diagnosis. Endoscopic biopsy often obtains insufficient specimens, while endoscopic mucosal resection of suspected lesions is satisfactory for histopathological examination. We here report a case of gastrointestinal bleeding which was finally diagnosed as multifocal epithelioid angiosarcomas in the gastrointestinal tract.
