During evaluation of a hydrocele in adults, which condition must be ruled out due to overlapping presentation?

• A. Epididymal cyst
• B. Testicular tumor
• C. Varicocele
• D. Spermatic cord torsion

Answer: (B)

When an adult presents with a scrotal swelling thought to be a hydrocele, it’s essential to rule out a testicular tumor because cancers can present as a painless, enlarging scrotal mass that may be mistaken for or concealed by a fluid-filled sac. Hydroceles involve fluid around the testicle and typically transilluminate, but an underlying or associated malignancy can be missed if you assume it’s purely a hydrocele. The correct approach is scrotal ultrasound with high-frequency probe and Doppler to assess the testicle for a solid intratesticular mass and to evaluate blood flow; tumor markers may be added if ultrasound raises suspicion. Epididymal cysts can also cause transilluminant swelling, and varicoceles have a different feel (often a “bag-of-worms”) and are not transilluminant, while torsion presents acutely with severe pain. The key point is to exclude a tumor due to its serious implications for diagnosis and management.
