Andrologia. 2020 Apr;52(3):e13517. doi: 10.1111/and.13517. Epub 2020 Jan 21.

Abstract

Primary rhabdomyosarcoma of tunica vaginalis is very rare. We report a case of a 15-year-old man presenting as hydrocele. Pre-operatively, no masses were detected by ultrasonography. Hydrocelectomy was performed. At surgery, a 0.8 cm polypoid nodule and diffusely thickened tunica were found. Pathologic examination finally revealed rhabdomyosarcoma. A PET-CT was then performed and indicated scrotal implantation metastasis. The patient underwent radical inguinal orchiectomy and was treated with chemotherapy and radiotherapy after surgery. At 12 months of follow-up, he remained disease-free.

Keywords: hydrocele; rhabdomyosarcoma; tunica vaginalis.
