title: Follicular dendritic cell sarcoma: a case report and review of the literature.
abstract: Follicular dendritic cells (FDC) are non-lymphoid, non-phagocytic accessory cells of the immune system and these cells are essential for antigen presentation and regulation of the reactions in germinal centers. Follicular dendritic cell sarcoma (FDCS) is a rare neoplasm that shows a low-to-intermediate malignant potential. The most commonly involved sites are the lymph nodes, but FDCS may also occur at a variety of extranodal sites, including the oral cavity, tonsils, gastrointestinal tract and liver. We describe here a 79-year-old woman who had FDCS with extensive lymph node involvement, dry cough, and an itching sensation. The patient improved after systemic chemotherapy.
