Extranodal follicular dendritic cell sarcomas are extremely rare neoplasms included under the hematolymphoid and dendritic group of neoplasms. Histologically, fascicular, whorled spindle cells with sprinkled lymphocytes are typical; however higher grade epithelioid morphology seen in a subset makes diagnosis of follicular dendritic cell sarcoma challenging. Rarity of occurrence, a wide histologic spectrum and a long list of differential diagnostic entities render follicular dendritic cell sarcoma an under-recognized entity susceptible to diagnostic pitfalls. Application of a judicious panel of immunohistochemical markers is imperative to avoid errors in diagnosis and patient management. We report here an extremely rare case of follicular dendritic cell sarcoma of the larynx- a hitherto unreported site.
