title: Hepatic follicular dendritic cell sarcoma without Epstein-Barr virus expression.
abstract: Follicular dendritic cell sarcoma of the liver is an uncommon pathologic entity, and only 5 cases have been reported previously. Herein, we report the first case, to our knowledge, of hepatic follicular dendritic cell sarcoma without evidence of Epstein-Barr virus infection. The patient is an elderly man who was found to have an incidental liver mass and then developed weight loss and fever. The diagnosis was based on the typical morphologic appearance of spindle cell proliferation associated with a brisk lymphoplasmacytic infiltrate and strong immunoreactivity to CD21 and CD35. Based on our experience and a review of the published reports, we summarize the clinical and pathologic features of hepatic follicular dendritic cell sarcoma and its surgical management.
