Intraparenchymatous adenomatoid tumor dependent on the rete testis: A case report and review of literature.

The adenomatoid tumor is the most frequent paratesticular tumor. It is a benign tumor, which in women is mainly found in the uterus and the fallopian tubes, while in men it is most frequently found in the epididymis. These lesions may also affect the testicular albuginea, the spermatic cord and, in exceptional cases, the testicular parenchyma, of which there are only 4 published cases, the ejaculatory ducts, prostate, etc. The clinical signs and imaging studies are, on many occasions, difficult to differentiate from malign intratesticular solid tumor, which can result in unnecessary orchidectomies. We present a new case of intraparenchymatous adenomatoid tumor dependent on the rete testis.
