Unilateral testicular microlithiasis associated with a seminoma

Unilateral testicular microlithiasis is an uncommon entity that is important because of its association with malignancy. We describe a case in which the initial clinical presentation was that of metastatic cervical lymphadenopathy. Subsequent sonographic examination of the testes revealed right testicular microlithiasis and a small, hypoechoic, ill‐defined mass, which proved to be a seminoma. Since testicular microlithiasis is highly associated with testicular malignancy, it cannot be considered a benign condition. Sonographic follow‐up examinations are warranted in patients with testicular microlithiasis to detect the possible development of malignancy. © 1997 John Wiley & Sons, Inc.
