Rete testis adenomatous hyperplasia: our experience.

The word "adenomatous hyperplasia of rete testis" (AHRT) was used by M. Nistal et Al. for the first time in an article about the cystic dysplasia of the testis (1976). AHRT is a benign lesion of the testis. The patient who came to our attention was studied with a testicular echo color Doppler that identified a solid, well circumscribed and hypoechoic mass of 4.5 x3.8mm as diameter, localized in the upper third of the right testicle and with a perilesional vascularization pattern. The preoperative study was based on an accurate medical history, on an ultrasound with contrast and on a RMI. The treatment consisted in an echo guided excisional biopsy of the testicular lesion, considering this as the best approach for those testicular neoformation difficult to define, with a lot of benefits for the patients, especially for those monorchid.
