Background: Penile schwannoma is a rare tumor. They commonly present as an asymptomatic, painless and slow growing mass. Other presentations include sexual dysfunction, most commonly dyspareunia, followed by erectile dysfunction, abnormal penile curvature or pain with ejaculation.
Case presentation: A 26-year-old male presented atypically with painful nocturnal penile tumescence, along with multiple nodules over the dorsal penis. Excision of multiple penile tumors under general anaesthesia was performed and histopathologic examination revealed benign schwannoma.
Conclusion: Our hypothesis is that the schwannoma lies along the axis of the dorsal penile nerve, and compression of this nerve occurs during his erection causing pain. However, there are limited presentations of painful erections in penile schwannomas, and we hope that future studies can help confirm this theory.

Keywords: Penile; schwannoma; painful tumescence; sexual dysfunction
