Introducción: La microlitiasis testicular (MT) es un hallazgo poco frecuente en el ultrasonogramacuyo significado clínico no se ha definido. El presente estudio se realizó en pacientes con tumores decélulas germinales de testículo para analizar la relación entre MT, los hallazgos histológicos y lasvariables clínicas.
Material y métodos: Se incluyeron 57 pacientes sometidos a orquiectomía radical por neoplasia testiculargerminal y se revisaron las variables clínicopatológicas y ultrasonográficas.
Resultados: Hubo 30 hombres (52,6%) sin MT y 27 hombres con MT (48,27%). Los pacientes conMT tuvieron mayor proporción de tumor germinal no seminomatoso (TGNS, 55,6% vs 30%, p=0,05),de cáncer testicular estadio II/III (51,8% vs 16,7%, p=0,005), de borde quirúrgico positivo (18,5% vs0%, p=0,021) y de invasión al cordón espermático (14,8% vs 0%, p=0,048). No se encontró diferenciasignificativa en relación a otras variables histopatológicas.
Conclusión: En este estudio se demostró una asociación entre MT en tumores testiculares con elhallazgo de TGNS, estadio clínico avanzado, borde quirúrgico positivo e invasión al cordón.

Introduction: testicular microlithiasis (TM) is a rare ultrasonographic finding whose clinical significance has not yet been properly defined. The present study was carried out in patients with testicular germinal cells¿ tumors in order to study the relationship between TM, historical findings and clinical variables.
Material and methods: 57 patients subjected to a radical orchiectomy for testicular germinal neoplasms were included in the study. Both clinicopathological and ultrasonographic variables were analyzed.
Results: No evidence of TM was found in 30 men (52,6%), whereas 27 did exhibit evidence of TM (48,27%). Patients with TM had a higher incidence of nonseminomatous germ cell tumor (NSGCT, 55.6% vs 30% p=0.048), stage II/III testicular cancer (51.8% vs 16.7%, p=0.005), positive surgical margins (18.5% vs 0%, p=0.021) and spermatic cord invasion (14.8% vs 0%, p=0.048). No significant difference with regard to other histopathologic variables was seen.
Conclusion: The present study showed a relationship between TM in testicular tumors and NSGCT in advanced clinical stage, positive surgical margins and cord invasion.
