A 93-year-old man presented with gross hematuria and a red, translucent papule on his proximal right lower leg (Figure 1). Tissue obtained via shave biopsy was weakly positive at the luminal zones for PSA and strongly positive throughout the cytoplasm for PSAP, which proved the lesions to be metastatic prostate adenocarcinoma (Figure 1).
Biopsies of corpus cavernosum (a) and bladder neck mass (b), both demonstrating poorly differentiated prostatic adenocarcinoma.

During cystoscopic evaluation of the patient's gross hematuria, a friable bladder neck mass was resected with loop electrocautery, and penile corporal tissue was also biopsied:both of which showed poorly differentiated prostatic adenocarcinoma (Figure 2).
