When EGCT is suspected, sonographic and physical examination of the testicles should be performed to evaluate for testicular lesion or atrophy; negative testicular ultrasound with current technology virtually excludes the possibility of occult primary lesion. Although EGCTs are known to be associated with elevated level of serum tumor markers, the utility of tumor markers in the presence of TM is not well understood. Current guidelines for TM follow-up and management do not include any potential correlation between TM and primary EGCT, an association that should be addressed on future updates.
