The Presentation and Treatment of Myointimoma: A Systematic Review and the First Case Report of Penile Myointimoma as a Cause of Urethral Obstruction.

Background/Objectives: Myointimoma is a rare, benign soft tissue tumor of the penis. We present a systematic review of the current literature and a case report of a 33-year-old male with a urethral stricture without discernible risk factors. Our aim was to investigate current knowledge on Myointimomas and increase the awareness of this entity. Methods: A systematic literature search was conducted across EMBASE, MEDLINE, PubMed, Scopus, Web of Science, and Google Scholar. Only 30 previously reported cases of this tumor are known-all located at the glans penis or in close proximity to it. Results: After the exclusion of non-eligible studies, 14 studies were included. Conclusions: Myointimomas are a relevant differential diagnosis in recurring cases of bladder outlet obstruction.
