BACKGROUND Dendritic and histiocytic cell neoplasms are rare malignancies that make up less than 1% of all neoplasms arising in lymph nodes or soft tissues. These disorders have distinctive disease biology, clinical presentations, pathology, and unique treatment options. Morphology and immunohistochemistry evaluation by a hematopathologist remains key for differentiating between these neoplasms...

Dendritic cell neoplasms are rare malignancies described with an increased frequency. They often involve the lymph nodes, but extranodal presentations are also described. The disease often has an indolent course. Surgery is the main modality though chemotherapy and radiation have also been tried. We present here a case of a 69-year-old male diagnosed to have follicular dendritic cell sarcoma of...

BACKGROUND Follicular dendritic cell (FDC) sarcoma is a rare neoplasm arising in lymph nodes but also in extranodal sites from accessory cells of the immune system that are essential for the function of antigen presentation and germinal center reaction regulation. FDC sarcoma has a significant recurrent and metastatic potential and for these reason it should be viewed as an intermediate grade m...
