Penile paraffinoma: the delayed presentation.

The injection of foreign substances into the penis for the purpose of augmentation may result in erectile dysfunction, voiding difficulties, and severe deformity. We report a case of penile paraffinoma in a 71-year-old man that developed nearly 40 years after undergoing a series of penile injections with an unknown substance. Penile paraffinoma can therefore present a diagnostic dilemma given its protracted latency period, after which time the initial injections have faded into distant memory.
