What sequence of evaluation is recommended for a suspicious testicular mass?

• A. MRI first
• B. Scrotal examination, transillumination, then scrotal ultrasound and serum studies
• C. Biopsy first
• D. Observation

Answer: (B)

Evaluating a suspicious testicular mass starts with simple, noninvasive assessment and targeted lab testing to avoid seeding a potential cancer. Begin with a careful scrotal examination and use transillumination to distinguish fluid-filled processes (like a hydrocele) from a solid mass. Transillumination helpfully flags fluid versus solid, and a solid, non-transilluminating intratesticular lesion raises concern for malignancy. The next essential steps are scrotal ultrasound with color Doppler and concurrent serum tumor markers. Ultrasound is the most informative, noninvasive imaging to confirm intratesticular versus extratesticular origin, evaluate the lesion’s characteristics and vascularity, and help differentiate cystic from solid masses. Serum markers such as AFP, beta-hCG, and LDH provide clues about the type of germ cell tumor and assist in staging and treatment planning. Biopsy is avoided because it can seed tumor cells and complicate management; if cancer is suspected, the standard course is to proceed with definitive surgical care via an inguinal approach. Observation alone is inappropriate for a mass that is suspicious for cancer. So the recommended sequence is scrotal examination and transillumination, followed by scrotal ultrasound with serum studies.
