Scrotal Leiomyoma: A Case Report of a Rare Intra-Scrotal Benign Mass

Introduction: Scrotal leiomyoma is a rare benign mesenchymal neoplasm that originates from smooth muscles. Up to now, the exact tumor properties remain unclear. Case Presentation: A 53-year-old male presented with intermittent mild pain and constant heaviness in the right scrotum for 1 year. The physical examination revealed a 6.5 cm by 5.5 cm by 5.5 cm sized, firm, mobile and non-tender lump within the inferior right scrotum. The ultrasound examination revealed a well-circumscribed and heterogenous hypoechoic tumor. MR imaging showed isointense on T1-weighted images, hypointense on T2-weighted images, and mild enhancement on post-contrast sequences. Then, he received simple tumor excision and further pathological examination demonstrated the diagnosis of typical leiomyoma. Conclusion: A full understanding of these rare tumor properties is the key to administering optimal treatment.
