Resumen

La neoplasia testicular intratubular es una lesión premaligna testicular asociada a tumores germinales primarios gonadales y extragonadales. La prevalencia de neoplasia testicular intratubular en pacientes infértiles llega al 2% en diferentes estudios. Presentamos el caso de un paciente azoospérmico con diagnóstico incidental de neoplasia testicular intratubular bilateral en la biopsia testicular realizada durante la recuperación quirúrgica de espermatozoides. En pacientes infértiles, las técnicas de recuperación espermática deben incluir el estudio anatomopatológico de parénquima testicular para descartar enfermedad maligna asociada. Los pacientes con alteración de la espermatogénesis tienen mayor riesgo de presentar otras alteraciones del desarrollo gonadal (neoplasias, hipogonadismo, entre otros) en el contexto de un síndrome de disgenesia testicular.

Abstract

Testicular intraepithelial neoplasia is a premalignant lesion associated to gonadal and extragonadal germ cell tumors. Testicular intraepithelial neoplasia prevalence in infertile men has reached 2% in some studies. This report presents the case of an azoospermic man with an incidental diagnosis of bilateral testicular intraepithelial neoplasia after testicular sperm extraction. In infertile men, sperm retrieving techniques have to include histological analysis of testicular tissue, to discard any chance of malignant component. Patients with spermatogenesis alterations have an increased risk to present other disruptions in gonadal development (neoplasms, hypogonadism, among others) in the context of testicular dysgenesis syndrome.
