Peritoneal epithelioid angiosarcoma: A case report

Introduction: Peritoneal angiosarcoma is an extremely rare sarcoma (0.01287% incidence per 100,000) with an aggressive course and a poor prognosis.

Patient concerns: A 61-year-old man working in Mainland China presented with a 1-month history of abdominal distension. A contrast-enhanced abdominal computed tomography (CT) scan revealed peritoneal carcinomatosis with massive ascites. However, his tuberculosis (TB) polymerase chain reaction was negative.

Due to the state of shock, he was transferred to an intensive care unit (ICU). Diagnoses: According to the pathology report, the neoplastic cells were positive for cytokeratin, cluster of differentiation 31 (CD31), cluster of differentiation 34 (CD34), and negative for cytokeratin 7 (CK7), cytokeratin 7 (CK20). Therefore, the diagnosis of epithelioid angiosarcoma was made. Interventions: The patient took 400 mg of Pazopanib once a day.
