Bilateral testicular microlithiasis with a unilateral testicular germ cell tumor: a case report.

There is an important association between testicular microlithiasis and germ cell tumors. Ultrasound findings of 1-3 mm echogenic foci within the testicular parenchyma may be noted. Testicular microlithiasis in the general population without germ cell tumors or cryptorchidism has been estimated between 0.05 and 0.6%. However, findings of microlithiasis in concordance with germ cell tumors can be as high as 40%. We present the case report of a man with bilateral testicular microlithiasis and a unilateral germ cell tumor. Discussion of the relationship between these two conditions is also reviewed.
