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.
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.
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.
阴茎神经鞘瘤是一种罕见肿瘤。它们通常表现为无症状、无痛且生长缓慢的肿块。其他表现包括性功能障碍，最常见的是性交困难，其次是勃起功能障碍、阴茎异常弯曲或射精疼痛。
一名26岁男性表现不典型，有夜间阴茎痛性勃起，阴茎背侧有多个结节。在全身麻醉下切除多个阴茎肿瘤，组织病理学检查显示为良性神经鞘瘤。
我们的假设是神经鞘瘤位于阴茎背神经轴线上，勃起时该神经受压导致疼痛。然而，阴茎神经鞘瘤中痛性勃起的表现有限，我们希望未来的研究能够证实这一理论。
