Discrete epithelioid cells: useful clue to Hodgkin's disease cytodiagnosis.

Diagnosis of Hodgkin's disease is made with more confidence than diagnosis of non-Hodgkin's lymphoma on cytology. This study was undertaken to describe the presence of granulomas and a new cytologic feature, discrete epithelioid cells (DECs), in smears from Hodgkin's disease. Fine-needle aspiration smears from 39 cases of biopsy-proven Hodgkin's disease, collected over a period of 43 months, were reviewed. Epithelioid granulomas were seen in 38.5% of the smears. DECs, which were noted in 70% of the cases, may be useful in raising the suspicion of Hodgkin's disease when other features are not evident; their presence should encourage the cytopathologist to obtain aspirations from other lymph nodes.
