Sertoli cell tumour of the testis.

Sertoli cell tumors (TCS) derivated from sex-cord estroma cells, are an uncommon variety of testicles neoplasms. A 66 year-old patient that came to the consultation for an increased scrotum of size present. Ultrasound viewed a hipoecoic nodule capable with testicular tumor, more secondary hidrocele. After undergoing the standard treatment, by means of groin radical orchiectomy, its pathologic analysis identified the lesion as Sertoli cell tumor conventional. The pathologic features that best correlate with a clinically benign course are as follows: a lower size tumor to 5 cm, mild nuclear atypia, a mitotic rate of less than 5 mitosis per 10 high power fields, and absent necrosis. Our case presented with these features. Follow-up of these neoplasms should be prolonged by the unusual of its presentation and a small percentage of cases are clinically malignant.
