a Small Lump in the Scrotum: Which Specialist to Consult?

If there is a small lump under the skin of the scrotum near the groin, it would be most appropriate to consult a urologist?

Hello doctor, I have noticed a small hard lump (approximately 3-5mm) just beneath the skin near the edge of my scrotum, on the right side, about 2 cm from the junction with my thigh.
It does not hurt when I pinch it and can be moved slightly under the skin.
What could this be, and should I see a urologist, dermatologist, or general surgeon? Thank you, doctor.

Based on your description, it may be a benign subcutaneous tumor.
However, I recommend that you visit a physician in person for an accurate assessment.

When you discover a small lump in the scrotum, it can understandably cause concern. The first step is to identify the nature of the lump, which can vary widely in terms of cause and significance. Given the description you provided—a small, movable, non-painful lump located near the edge of the scrotum—there are several potential explanations.

Common causes of scrotal lumps include:
1. Epididymal Cyst: This is a fluid-filled sac that develops in the epididymis, which is the tube that stores and carries sperm. These cysts are usually benign and can be asymptomatic, meaning they do not cause pain or discomfort.

2. Spermatocele: Similar to an epididymal cyst, a spermatocele is a cyst that forms in the epididymis and contains sperm. They are also typically painless and may not require treatment unless they cause discomfort.

3. Varicocele: This is an enlargement of the veins within the scrotum and can sometimes present as a lump. Varicoceles are more common on the left side but can occur on either side.

4. Hydrocele: This is a buildup of fluid around the testicle, which can cause swelling in the scrotum. Hydroceles are usually painless and may resolve on their own.

5. Lipoma: A lipoma is a benign tumor made of fat tissue. These can occur anywhere in the body, including the scrotum, and are generally harmless.

6. Inguinal Hernia: Sometimes, a hernia can present as a lump in the scrotum, especially if it is pushing through the inguinal canal.

7. Testicular Tumors: Although less common, any new lump in the scrotum warrants consideration of the possibility of a testicular tumor, which can be malignant.

Given these possibilities, the next step is to consult a specialist. In this case, a urologist would be the most appropriate choice. Urologists specialize in the urinary tract and male reproductive system, making them well-equipped to evaluate and diagnose conditions related to the scrotum and testicles.

During your visit, the urologist will likely perform a physical examination and may recommend imaging studies, such as an ultrasound, to get a clearer picture of the lump's characteristics. This will help determine whether it is benign or if further investigation is needed.

While dermatologists focus on skin conditions and general surgeons handle a wide range of surgical issues, a urologist's expertise in male reproductive health makes them the best fit for evaluating a scrotal lump.

In summary, if you find a small lump in your scrotum, it is advisable to consult a urologist. They will provide a thorough assessment and guide you on the necessary steps for diagnosis and treatment, if needed. Remember, early evaluation is key to addressing any potential issues effectively.
