Myopericytoma in the corpus cavernosum of the penis: A case report of a rare disease

INTRODUCTION: Myopericytomas usually occur in the extremities of older individuals; however, they also rarely occur in the penis. We report a case of myopericytoma in the corpus cavernosum of the penis and review the relevant literature. CASE PRESENTATION: A 76‐year‐old man presented with a slow‐growing painless nodule on the left side of the penis. On physical examination, a non‐tender, 7‐mm mass was palpable. This tumor showed inhomogeneous low signal intensity on T2‐weighted magnetic resonance imaging. The mass was excised and a myopericytoma diagnosed by pathological examination of the operative specimen. CONCLUSION: We here report a rare case of myopericytoma in the corpus cavernosum of the penis. To the best of our knowledge, this is the second reported case of a myopericytoma in the penis and the first in the corpus cavernosum of the penis. Clinicians should keep this rare possibility in mind when investigating a mass in the penis.
