Single nodule on the glans penis: metastatic lesion from an unusual carcinoma of the prostate.

An inflammatory nodule developed on the glans penis of a 79-year-old man. Histological examination confirmed the diagnosis of metastasis from a carcinoma of the prostate. This case is of interest in view of the rarity of this metastatic localization and the very unusual microscopic pattern of the primary cancer (epidermoid carcinoma).
