Intraoperative ultrasonographically guided biopsy in testicular sarcoidosis: a case report.

We present a case of sarcoidosis with involvement of a solitary testis that was discovered incidentally on an ultrasonogram of the scrotum. This appears to be case 8 of sarcoidosis with genitourinary involvement limited to the testis. We believe it is the second report of intraoperative ultrasonography used to locate and perform a biopsy of impalpable testicular lesions. We consider this technique to be useful in instances of solitary gonads or in cases of bilateral lesions.
