RationaleAngiosarcoma is a highly invasive tumour with a low incidence rate but high rates of local recurrence and distant metastasis and a poor prognosis. Understanding the endoscopic characteristics of angiosarcoma will help with early diagnosis and treatment of this disease.Patient ConcernsThe patient was a 77-year-old female who was admitted to the hospital due to recurring melena for 3 months. Outpatient gastroscopy showed that the patient had multiple gastric erosions. Colonoscopy revealed the presence of multiple protruding lesions in the colon and multiple rectal polyps. Pathological biopsy indicated that the patient had a tubular adenoma, which was removed by endoscopic resection.DiagnosesPostsurgical pathologic assessment suggested that the histological subtype was epithelioid angiosarcoma. Positron emission tomography-computed tomography (PET-CT) revealed multiple metastases in the lymph nodes and bone.InterventionsThe patient underwent acid suppression to protect the stomach, fluid supplementation and red blood cell infusion, and subsequently, surgery, radiotherapy and chemotherapy were recommended. The patient's family refused further treatments for the patient and requested discharge.OutcomesThe patient refused further treatment and was not followed-up.LessonsColorectal angiosarcoma is an extremely rare and highly malignant tumour, and understanding its endoscopic morphology will help aid in its diagnosis.
