Follicular Dendritic Cell Sarcoma of tonsil treated by Transoral Video-laryngoscopic Surgery （TOVS）

Abstract

Follicular dendritic cell sarcoma （FDCS） is a rare neoplasm arising from follicular dendritic cells, which are antigen-presenting cells in the lymphoid follicles. Herein, we report a case of tonsillar FDCS of a 74-year-old woman with the complaint of an asymptomatic tonsillar tumor. The biopsy revealed the histopathological diagnosis as FDCS. We treated the case with radical tonsillectomy by TOVS. The resection margin was negative and adjuvant therapy was not indicated. At the 6-month follow-up after the operation, the patient showed no sign of disease recurrence and the post-operative function was satisfactory. We discuss the treatment strategy for FDCS.
