title: Fine-needle aspiration cytology of a para-aortical solitary plasma-cell tumor.
abstract: Extramedullary plasma-cell tumor (EMP) is a very rare disease and mainly arises in the head and neck area. An EMP arising in the paraaortical space was diagnosed by fine needle aspiration cytology and immunocytochemistry, in a 48-year-old male. Smears were cellular and showed dissociated monomorphic plasma cells. Immunocytochemistry demonstrated monoclonal expression of kappa-light immunoglobulin chain and CD38 positivity. Cytomorphology and immunocytochemical profile allowed a definitive diagnosis of plasmacytoma.
