Paratesticular leiomyoma in the pediatric age

Paratesticular leiomyoma is an extremely rare benign neoplasm in the pediatric population, with variable clinical presentations that can mimic other scrotal pathologies.

We present two pediatric patients with paratesticular leiomyoma. The first case was an 11-year-old boy with a long-standing, asymptomatic paratesticular mass, initially suggestive of polyorchidism, approached via a scrotal incision. The second case was a 14-year-old adolescent who presented with testicular pain, with ultrasound findings suggestive of a neoformative process, which required an inguinal exploration. In both cases, complete excision of the lesion was performed, preserving the testicle, and the diagnosis was confirmed by pathology.

Paratesticular leiomyoma can pose diagnostic challenges in pediatrics. Complete excision is curative, and the prognosis is excellent.
