title: Hodgkin's lymphoma associated with plasma cell neoplasia: cytological features and review of the literature.
abstract: Hodgkin's lymphoma (HL) associated with plasma cell neoplasia is extremely rare. Here, we report one case diagnosed by fine-needle aspiration biopsy (FNAB) and review the clinical features of 15 previously reported cases. Our specimen was obtained by FNAB of an enlarged right inguinal lymph node. Air-dried Diff-Quik (DQ)-stained slides and alcohol-fixed slides stained with hematoxylin-eosin (H&E) and Papanicolaou stains were reviewed. The specimen was cellular, consisting of lymphocytes and plasma cells. Flow cytometric analysis revealed a monoclonal (M) plasma-cell population. Admixed large atypical mono- and binucleated cells immunoreactive for CD30 were noted also. A diagnosis of plasma-cell neoplasm associated with classic HL was confirmed histologically after surgical removal of the lymph node. The diagnosis of both HL and plasma-cell neoplasia in the same patient is exceedingly rare. Adding another case to the 15 previously reported cases was unique because our case was diagnosed through FNAB.
