A 80-year-old woman admitted for hypochondoralgia was found in abdominal computed tomography to have a heterogenous mass 9 cm in diameter in the right hepatic lobe. Surgery was conducted for a suspected rnesenchymal tumor arising from the abdominal wall or originating in the liver. Operative findings showed that the tumor originated in the diaphragm. We resected the tumor. Histologically, the tumor consisted of spindle and pleomorphic cells. Mitotic cells were seen 8/10 HPF, and atypical mitosis was sporadically present. Immunohistochemical testing was positive for CD34, vimentin, and glycogen, and negative for S-100 and desmin, identifying the tumor as a malignant solitary fibrous tumor of the diaphragmatic peritoneum. Eight months post operatively, the patient is doing well, without evidence of recurrence.
