A 76-year-old man had been treated for carcinoma of the prostate for approximately two years with radiation, bilateral orchiectomy, and chemotherapy.

The cytological study showed clusters of atypical glandular cells that were moderately well differentiated and compatible with prostatic adenocarcinoma. The original diagnosis had been established by aspiration of the prostate.The presence
