We report the first case, to our knowledge, of a solitary fibrous tumor of the peritoneum resected by laparoscopy. A 47-year-old man found in ultrasonography to have a space-occupying hepatic lesion and admitted for investigation of an abdominal mass had laboratory findings within normal limits, except that T-Bil was high. Ultrasonography showed a 36-mm tumor at the lower border of the right hepatic lobe. Computed tomography showed an extrahepatic tumor contacting the abdominal wall that had high density in the arterial phase. Magnetic resonance imaging showed an extrahepatic tumor markedly enhanced in the arterial phase. At laparoscopy, the tumor arose from the peritoneum of the right abdominal wall independently of the liver and other organs. We coagulated and divided the feeding artery to the tumor with a laparoscopic scalpel and resected the tumor laparoscopically. The resected specimen was a 36-mm encapsulated whitish solid tumor. Microscopically, it consisted of irregularly arranged spindle cells against a collagenous background. No malignant component was found. Immunohistochemically, tumor cells were positive for CD34 and bcl-2 but negative for S-100, SMA, and EMA. Based on these findings, this lesion was definitively diagnosed as a solitary fibrous tumor.
