Adenomatoid tumor of intratesticular localization.

The germinal cell tumor represents the most common malignancy of the testicular tissues. Benign testis tumors are exceptional, and in this situation organ preservation should be considered. The adenomatoid tumor is the most common paratesticular type with anatomic distribution limited to the epididymis, testicular membranes and rarely to the spermatic cord. Its intratesticular localization is very rare. We report here the clinical case of a 32-year-old man with a testicular tumor who came to our department with a 6-month growth of a testicular mass (normal alpha-fetoprotein and beta-HCG). The pathologic report revealed a solid and small tumor at the lower pole of the testicle with total intratesticular tumor growth (adenomatoid tumor of intratesticular localization). Because of its rarity, the clinical, diagnostic and therapeutic aspects and the possibilities of testicular preservation are discussed.
