The cytologic findings in fine needle aspirates of a previously treated prostatic cancer metastatic to both breasts in a 65-year-old man are described. The prostatic origen of the poorly differentiated adenocarcinoma cells was demonstrated by identification of cytoplasmic prostate-specific antigen. The clinical importance of a conclusive diagnosis differentiating a primary from a metastatic lesion is discussed; this case illustrates the value of immunocytochemical analysis as an aid to cytomorphologic diagnosis in making such determinations.
