Tricorporal priapism postradical cystoprostatectomy: first sign of recurrent urogenital malignancy.

Priapism usually involves the whole length of a corpus or two corpora. Rarely is priapism segmental, especially proximally, and seldomly does it involve all three corpora. The causes of priapism are varied, but priapism due to solid malignancy is an extremely uncommon entity. The usual malignancy is urogenital. The disorder is frequently a manifestation of extensive pelvic extension of the primary disease; less commonly, it is associated with pelvic recurrence after seemingly curative surgery. In cases of malignant recurrence, priapism is rarely the first sign of such recurrence. We report a case of proximal tricorporal priapism, secondary to penile metastasis of a bladder malignancy postradical cystoprostatectomy. In this case, priapism was the first sign of disease recurrence and occurred in the absence of pelvic recurrence. This is the first such report of which we are aware.
