ABSTRACT
In spite of its rarity, hepatic angiosarcoma is of special interest because specific risk factors such as thorium dioxide, arsenic, and vinyl chloride have been identified. We report a case of histopathologically confirmed primary angiosarcoma of the liver which was found in a farmer. In this case, 73-ear old man was presented with right upper abdominal pain and fatigue. Abdominal ultrasonography, CT scan and MRI revealed a mass occupying broad area of the right lobe of the liver. Histopathologic diagnosis of angiosarcoma was made by percutaneous needle biopsy.

Intra-abdominal desmoplastic small round cell tumor has been described in the literature since 1989. It is characterized by the occurrence in ages less than 40 with male predominance, an intra-abdominal location, and small round to oval shaped tumor cells with divergent differentiation in the background of the desmoplastic stroma. We recently experienced this tumor in an inguinal lymph node of a 36-year-old man. It is suspected that it metastasized from a lower intra-abdominal tumor. Immunohistochemical stains for keratin, epithelial membrane antigen, vimentin, S-100 protein and neuron specific enolase were positive. This is the first documented case in Korea. Herein, we report on this tumor with a review of literature.
