[Paratesticular leiomyosarcoma: report of a new case].

Objective: To report an additional case of paratesticular leiomyosarcoma.
Methods: Herein we describe a 68-year-old male patient that presented with a growing, indolent, right inguinoscrotal lesion that he had noted several weeks earlier. Physical examination showed a mass involving the distal right spermatic cord and was confirmed by ultrasound and CT. Analyses were normal. Radical orchidectomy with high ligation of the right spermatic cord was performed.
Results: Histopathological and immunohistochemical studies demonstrated a well-differentiated paratesticular leiomyosarcoma. Local recurrence was observed at 3 1/2 years' follow-up. Complete excision of the tumorous tissue was performed with no other adjuvant therapy. Six months thereafter, there is no evidence of local recurrence or distant metastasis.
Conclusions: This tumor type is uncommon. Like other authors, we believe that orchifuniculectomy is the treatment of choice. Furthermore, adjuvant radio or chemotherapy does not significantly influence survival in these patients.
