Unilateral testicular microlithiasis.

Testicular microlithiasis is a rare pathology which usually affects both testicles (less than 100 cases have been described in the literature), histologically characterized by numerous calcified deposits situated inside the seminiferous tubules, the diameter of which does not usually exceed 2 mm. The pathogenesis of the phenomenon is not completely clear; it has however been noted that there is a higher incidence in patients affected by cryptorchidism, subfertility, Klinefelter's syndrome and in particular those with testicular neoplasms, although the reason for this remains obscure. The case reported seems atypical in that there is no association with the conditions mentioned above and the finding is monolateral, something which is unusual in the literature reviewed.
