This article describes the case of a 43-year-old patient with HIV infection who presented with abdominal pain of 4 months duration along with swelling in the right upper part of abdomen which had increased in severity 4 weeks prior to presentation. After a complicated diagnostic process, the diagnosis of metastatic liver angiosarcoma was made by history and imaging. We reviewed previous cases of angiosarcoma described in the English literature to determine their risk factors, diagnosis and treatment, and we found that angiosarcoma is extremely rare, especially metastatic liver angiosarcoma. To the best of our knowledge, this may be the first case of primary angiosarcoma of the large intestine with metastasis to the liver reported in the English literature.
