Abstract
Paneth cell-like metaplasia has been reported in the epithelium of the epididymis and prostatic adenocarcinomas. We studied the expression of group II phospholipase A2 (PLA2), a marker of Paneth cell differentiation, in six orchiectomy specimens with Paneth cell-like metaplasia. Both immunohistochemistry for group II PLA2 protein and in situ hybridization for the mRNA of group II PLA2 gave negative results in all six cases but positive reaction for lysozyme. The results show that the cells of the Paneth cell-like metaplasia are not true Paneth cells.
