Scrotal Masses

Definition :
Scrotal masses are areas of fluid or solid material in, on or around your testicles. Although they may indicate a less serious or harmless condition, scrotal masses may also signal something as serious as cancer.

The location of the testicles in the scrotum, a loose bag of skin underneath your penis, keeps them at a temperature lower than that within your abdominal cavity. The lower temperature is needed for adequate sperm production.

The relatively exposed location of the testicles and scrotum makes them prone to injuries, but it also makes them easy to examine for the presence of scrotal masses.

Have your doctor check out any unusual lumps or swelling in, on or around your testicles. Treatment of scrotal masses depends on the cause.

Causes:
Scrotal masses have various causes, including cysts, infection, inflammation, trauma, inguinal hernia and tumors. The tumors may be noncancerous (benign) or cancerous (malignant). Because of the possible seriousness of a scrotal mass, it's important to have a doctor check out any swelling or lumps. Specific causes of scrotal masses include :

  • Epididymitis. This infection in the tubular coil (epididymis) that collects sperm from the testes produces pain in the top and rear of the scrotum. Epididymitis is often caused by bacteria. The pain may be severe. Fever and swelling also are common.
  • Spermatic cyst (spermatocele). This common type of painless, benign cyst develops adjacent to the epididymis near the top of the testicle.
  • Hydrocele. This soft, usually painless swelling in the scrotum is a collection of watery fluid in the sheath that holds the testicle. Normally this sheath contains just enough fluid to lubricate the testicle. When your body produces too much fluid or can't absorb enough fluid, the excess liquid creates a hydrocele. Hydroceles are a common cause of scrotal swelling and may occur on one or both sides.
  • Hematocele. This type of scrotal mass is generally caused by trauma to the area. It results in blood collecting in the sheath that holds the testicle, and is usually painful.
  • Varicocele. Enlarged (varicose) veins cause this painless, benign source of scrotal swelling, more commonly on the left side. Blood backs up in the veins leading from the testicles because of a problem with valves inside the veins. The swelling is usually painless. The varicocele itself isn't serious, but it may contribute to infertility.
  • Orchitis. This inflammation of the testicle is often due to a bacterial infection or the mumps virus. It involves pain and swelling in the scrotum along with a feeling of added weight in the scrotum. Orchitis can permanently damage one or both testicles, resulting in diminished size of the testicle, inadequate hormone production and infertility.
  • Inguinal hernia. An inguinal (ING-gwih-nul) hernia develops when abdominal contents, usually the small bowel, protrude through a weak point of the abdominal wall in the groin area, where the blood vessels and ducts from the testicles enter your abdominal cavity. The result is a bulge in your groin area that may extend into the scrotum and be painful or uncomfortable.
  • Cancer of the testicle. This condition is serious and identified by a lump or swelling within a testicle, sometimes accompanied by a heavy feeling in a testicle. If detected and diagnosed early, this type of cancer often is treatable.

When to seek medical advice :
See your doctor if you detect any pain, swelling or lumps in your testicles or groin area, especially if these signs and symptoms linger. Make an appointment with your doctor even if a lump in your testicle isn't painful. Many testicular cancers aren't initially painful.

Symptoms:
The testicles (testes) are located inside the scrotum, a loose bag of skin below your penis. They produce male hormones and sperm. Signs and symptoms of scrotal masses include :
  • A lump or swelling in the scrotum
  • Local pain or tenderness

Diagnosis:
Most men discover scrotal masses themselves, either unintentionally or while doing a testicular self-examination to check for lumps.

If you alert your doctor to a scrotal mass, or he or she discovers a lump during a routine office visit, a physical exam and lab tests can confirm an infection or another cause. You may also undergo an ultrasound examination. This painless test passes sound waves through your scrotum to make an image of the contents of your scrotum.

Treatment:
Most scrotal masses require minimally invasive treatment or no treatment at all, but some require more serious procedures.

  • Epididymitis. This usually acute condition can be treated with antibiotics.
  • Spermatocele. Most spermatoceles are small, cause no symptoms and require no treatment. However, sometimes they can grow large enough to cause signs and symptoms such as pressure, pain or swelling in the scrotum and require surgical removal. Draining the fluid by puncturing the spermatocele through your skin may provide temporary relief. But the fluid may accumulate again soon after.
  • Hydrocele. Usually, you don't need treatment for a hydrocele unless the scrotum is so swollen that it's uncomfortable.
  • Hematocele. Surgical drainage is necessary if the hematocele becomes infected, is large or it doesn't seem to be getting better on its own.
  • Varicocele. If you have a varicocele that's contributing to infertility, surgically tying off the varicocele (ligation) improves your chances of becoming fertile again. Additionally, your doctor may recommend treatment if your symptoms are bothersome.
  • Orchitis. Doctors use antibiotics to treat orchitis associated with bacterial infections. Treatment for orchitis associated with viral infections, such as mumps, is only by conservative means, such as rest and pain-relieving medications.
  • Inguinal hernia. Your doctor may recommend surgery if your hernia is painful or bothersome. Hernias can sometimes recur after surgery.
  • Cancer of the testicle. Stage I testicular cancer, in which cancer is found only in the testicle, and stage II testicular cancer, in which cancer has spread to the lymph nodes in your abdomen, are successfully treated in most cases. Later stage testicular cancers, in which cancer has spread beyond the lymph nodes to other regions of your body, such as your lungs or liver, can be successfully treated in about 70 percent of cases.

Generally, doctors use the following treatments for testicular cancer :

  • Radical inguinal orchiectomy. This surgical procedure involves removal of one or both testicles through an incision in your groin. Lymph nodes in your abdomen also may be removed (lymph node dissection). If only one testicle is cancerous and removed, it's possible that the other testicle will become cancerous at some time in the future. As a result, your doctor will likely recommend regular follow-up exams with a urologist.
  • External beam radiation therapy. This treatment uses high-dose X-rays or other high-energy radiation to kill cancer cells.
  • Chemotherapy. Chemotherapy is used to kill cancer cells outside the testicle. This drug therapy is usually given by intravenous (IV) infusions in four cycles, typically in the hospital. In some cases, chemotherapy may also be given by intramuscular injection or in pill form. Chemotherapy has made the biggest difference in reducing death from testicular cancer.
  • Stem cell transplant. In this procedure, stem cells are filtered from your blood and frozen. You then undergo chemotherapy, with or without radiation, to destroy the remaining cancer cells in your body. This chemotherapy also destroys your remaining bone marrow. The frozen marrow is then thawed and injected back into you through a needle in a vein.

    While this relatively new treatment for testicular cancer has had some promising initial results, it's not routinely recommended by doctors because traditional chemotherapy treatments are typically very successful.

Surgery may be in combination with radiation therapy or chemotherapy or both. Your treatment depends on the type and stage of your cancer. Your age and overall health also are factors in choosing treatment options for testicular cancer.
