Bump on Scrotum

Question:

I discovered a small bump on my genital area yesterday. It was pink and was located on my scrotum. When I squeezed it a small amount of clear fluid secreted out. A few days ago too, I discovered a bump on scrotum and assumed it was a bug bite. That is also still there. I remember experiencing a similar single red bump on scrotum about a year ago. At that time, when I tried to squeeze it, there was a secretion of whitish-yellow puss and blood. This used to itch a little, but was painless. Can you please guide me on understanding what this is? I am worried about STD and anxious. I am sexually active, and I do not want to infect anyone else if I have a sexually transmitted disease. Could it be an infection or something more sinister, like cancer?

Answer

Finding a small lump on scrotum can mean various things. It can be a result of a bug bite, sexually transmitted disease, infection or even testicular cancer. It is natural for most men to instantly suspect that they have testicular cancer, especially with all the hype in the media about cancer. However, a lump in the scrotum can occur due to other less harmful and more common reasons too.

  • Hydrocele – Hydrocele is the collection of fluid in the scrotum. The scrotum is the loose, fleshy sac that holds the testicles. There is a tube in the testis that takes sperm to the penis. The sac in the scrotum, next to the testis collects fluid. This usually occurs on one side of the testes, but can occur on both sides too. If you feel a small, fluid-filled balloon inside the scrotum, you could be having Hydrocele. The size of the lump can vary greatly. It can start out the size of a pea and go on to become larger. Most often Hydrocele heals itself. However, if it gets larger, medical treatment is advised.
  • Spermatocole – This is a small cyst also known as spermatic cyst that commonly develops in the epididymis. This is a small tube, found in the upper section of the testicle that collects and transports sperm to the penis. This abnormal sac is filled with a clear liquid that may contain sperm. You may feel the bump on scrotum that is slightly painful, and will increase in pain with the enlargement of the cyst. There might also be some swelling behind the testicle.
  • Orchitis – Orchitis is an infection that is caused by various bacteria and viruses. One of the most common causes of orchitis is mumps. It can also be caused by sexually transmitted diseases such as gonorrhoea or Chlamydia. It can also occur from urinary tract infections, or if you were not vaccinated against mumps. Surgeries in the urinary tract can also lend to such circumstances. If you experience groin pain, pain with intercourse, scrotal swelling, or a feeling of heaviness on one side of the testicle you may be having orchitis.
  • Varicocele – The testicle consists of many veins. If any one of these veins becomes enlarged, it prevents blood from flowing properly. This causes the veins to swell and widen. A painless, small lump on scrotum is one symptom of varicocele. This can be a result of a kidney tumour if it is experienced by older men. If this occurs in younger men, and is not treated it can lead to infertility.

A bump on scrotum, even a single red bump on scrotum, must not be ignored. If you discover a lump in the scrotum, you should alert your doctor to this fact as soon as possible. Waiting around for the lump to disappear might cause unnecessary complications. Therefore, it is vital to get the lump evaluated and get a proper medical prognosis as to the cause of the lump and the required medical treatment.
