BACKGROUND: Solitary fibrous tumor of the liver is a rare neoplasm. So far, 23 cases have been described in the English literature. We reported an additional case. METHODS: A 46-year-old woman presented with abdominal mass for 2 weeks. Both abdominal sonography and CT scan showed a solid mass occupying the right lobe of the liver. Right lobectomy was performed and the tumor was resected. RESULTS: Pathological examination showed spindle cell and fibroblast-like cells within the collagenous troma. On immunohistochemical staining, these spindle tumor cells showed diffusely CD34 positive reactivity. The post-operative course was uneventful. The patient recovered smoothly, and was alive half a year without evidence of disease recurrence. CONCLUSIONS: The proper diagnosis was depended on CD34 immunohistochemical study. The number of solitary fibrous tumor of the liver reported to date is too limited to confirm the definite prognosis of the tumor.
