Solitary fibrous tumor is a very uncommon mesenchymal neoplasia in the liver. We report a new case in 52 year old patient. The tomographic image revealed a solid, well delimitated tumor, localized at the right hepatic lobe. Macroscopically, it had rounded borders, was expansive and white. Microscopically it had a spindle cell pattern with extensive areas of hyalinization and hemangiopericytic vessels; it was positive with inmunohistochemestry markers for CD34, CD99 and Bcl-2. Despiteitsrarity, solitary fibrous tumor shouldbe considered among the differential diagnosis of the spindle cell tumors of the liver.
