Malignant priapismus induced by adenocarcinoma of the prostate.

Penile metastasis of adenocarcinoma of prostate is an extremely rare clinical entity and even less of such cases presenting with malignant priapism. Management of priapism with penile shunting is recommended in this case. No consensus beyond personal recommendation from other studies found in this case due to the relative rarity of the disease and the associated lack of data. In this study, we present a case of malignant priapism due to penile metastasis of adenocarcinoma of the prostate, an extremely rare clinical entity and a more uncommon site of metastasis.
