Polyarteritis nodosa of the penis.

The course of polyarteritis nodosa in a patient showing an isolated nodule localized to the glans penis is described. The underlying disease was not recognised and the patient was wrongly thought to have a penile cancer. Treatment with radiotherapy and Bleomycin had no effect and he subsequently died in uraemia. Postmortem examination revealed polyarteritis nodosa involving the kidneys and also causing localized changes to the glans penis.
