Follicular Dendritic Cell Sarcoma of the Liver

Follicular dendritic cell sarcomas are a rare form of malignancy of the follicular dendritic cells. More than half of follicular dendritic cell sarcomas are of nodal origin, while the rest can involve the tonsils, nasopharynx, pancreas, and peritoneal tissues. Follicular dendritic cell sarcoma mimics a number of tumours and tumourlike conditions, and should be considered in the differential diagnoses of a bulky soft tissue mass in relatively asymptomatic individuals. This report is of a patient with follicular dendritic cell sarcomas of the liver and, to the best of the authors’ knowledge, is the first reported case in the Asian population. The radiological and pathological findings are described.
