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 tumour-like 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.

濾泡樹突細胞肉瘤是一種罕見的惡性腫瘤。一半以上的濾泡樹突細胞肉瘤為淋巴結來源，其餘的侵犯扁桃體、鼻咽、胰腺和腹膜組織等。濾泡洲樹突細胞肉瘤與多種腫瘤和瘤樣組織類似；對於臨床發現體積大的軟組織腫塊，但無明顯症狀的病例，應將濾泡樹突細胞肉瘤列為鑑別診斷之一。本文報告首名病灶位於肝臟的濾泡樹突細胞肉瘤的亞洲病人，描述該病相關的放射學和病理特徵。
