Abstract
Follicular dendritic cell (FDC) sarcomas, also known as dendritic reticulum cell tumors, are uncommon neoplasms arising from antigen-presenting cells in B-lymphofollicles of nodal and extra-nodal sites. It is considered as an intermediate grade malignancy since it has significant recurrent and metastatic potential. We report a case of FDC sarcoma arising in the neck. A 56-year-old female presented with a left neck tumor. Neck dissection was performed. Microscopically, the tumor showed spindle-shaped stromal cells with large oval and polygonal nuclei. Immunohistologically, the cells were positive for CD21 and CD35, consistent with FDC sarcomas. Adjuvant chemotherapy of cyclophosphamide/doxorubicin/vincristine/prednisone (CHOP) was given. Literature review provides the current information for the diagnosis and treatment of this unusual tumor.
