Giant scrotal leiomyoma: Report of a rare case and review of literature

Background: Leiomyoma is a benign tumour of smooth muscles that can arise almost anywhere in the body; however, scrotal Leiomyomais a rare entity. It may originate from dartos muscle, epididymis or spermatic cord. The neoplasm has an insidious course, and clinically it may mimic many intrascrotal tumours, including testicular cancers, resulting in diagnostic challenges. Case report: A 20-year-old student evaluated for a painless right testicular swelling of lyear duration, suspicious of right testicular cancer. He had right radical orchidectomy done, but the histology result of the specimen came out to be para- testicular leiomyoma compressing and causing total atrophy of the right testis, the specimen measured 10×7×6cm and weighed 600g. Post-operative condition and follow up were satisfactory. Conclusion: Scrotal leiomyoma is rare and when it presents as huge mass can cause challenges in diagnosis and treatment, particularly in developing countries. Close follow-up and molecular testing are important in detecting renal cell carcinoma in case of hereditary autosomal dominant disorders that may coexist with this tumour
