Is testicular macrocalcification a risk for malignancy? Tumor development on ultrasonographic follow-up of preexisting intratesticular macrocalcification

Testicular macrocalcification is an uncommon finding when imaging the scrotum with ultrasonography (US). It is not normally a recognized risk factor for development of testicular malignancy, and patients are not usually offered follow-up US examinations or counseled for self-examination. This aspect is in distinction to patients with testicular microlithiasis (usually with an additional risk factor), who are offered follow-up on the assumption that microlithiasis is associated with malignancy. We report a series of 6 patients with predetermined testicular macrocalcification, with development of a malignancy on follow-up US. We encourage US follow-up examinations for patients with macrocalcification, potentially in a similar manner as for those with testicular microlithiasis.
