Testicular microlithiasis in a unilateral undescended testis: a rare phenomenon.

Testicular microlithiasis (TM) is a rare benign condition with presence of multiple small microcalcifications in the seminiferous tubules. Though the aetiology is unknown, TM has been described in association with a variety of urological conditions. We report the clinico-pathological features of a 12-year-old male child who underwent orchidectomy for undescended testis. Histopathological examination of the excised testis showed multiple small intratubular calcifications without any evidence of testicular neoplasia. TM is an unusual phenomenon that should be kept in mind while evaluating testicular biopsies. Though it behaves in a benign manner in most of the cases, patients with positive family history of testicular cancer should be followed-up for testicular tumour.
