Supernumerary testicle: case report and bibliographic review.
OBJECTIVE
We report a case of supernumerary testis, a rare anomaly with only around 100 cases reported in the literature.


METHODS
We describe the case of a 26-year-old man who consulted for a left paratesticular tumor. Physical examination and ultrasound  showed a 2-cm nodular lesion  over the left epididymis. The lesion was confirmed as supernumerary testis by surgical examination and biopsy and was subsequently excised, given the malignancy potential.


RESULTS
The supernumerary testis was evaluated using two standard classifications, one assessing function and embryological development, and  the other assessing  topography, anatomy, and reproductive potential.


CONCLUSIONS
The differential diagnosis for an intrascrotal mass should include the possibility of a supernumerary testis; hence, surgical examination  and biopsy  are necessary. Supernumerary testes should be excised in the case of pain, dysplasia, or in situ carcinoma, or whenever the biopsy is inconclusive.
