A small bump on the top of the head?


Hello Doctor: I have a raised lesion on the top of my head, approximately in the center, with a diameter of about one centimeter.
The color is slightly more pink than the normal scalp, and it is hard and immovable.
It only hurts a bit when pressed hard, and it has been present for about two years.
Yesterday, I consulted an ENT specialist while seeking treatment for a cold, and the doctor mentioned that it is a "subcutaneous cyst." I would like to ask the following questions: 1.
Can a subcutaneous cyst occur on the scalp? 2.
I have read that subcutaneous cysts usually require surgical removal to resolve.
If the lesion on my head is indeed a subcutaneous cyst, is it possible to perform surgery on the scalp? Will I need to shave my hair for the procedure? 3.
Which medical specialty should I consult for this issue? Thank you for taking the time to respond!

More Info


Understanding scalp bumps can be a source of concern for many individuals, especially when they persist for an extended period. Based on your description, it seems you have a bump on your scalp that has been present for over two years, is firm, and causes discomfort only when pressed. The ENT doctor you consulted suggested it might be a "subcutaneous cyst." Let's address your questions one by one.

1. Can subcutaneous cysts occur on the scalp?
Yes, subcutaneous cysts can indeed develop on the scalp. These cysts, often referred to as epidermoid cysts or sebaceous cysts, are common benign growths that can form when hair follicles become clogged with keratin or other debris. They can appear anywhere on the body, including the scalp, and are typically painless unless they become inflamed or infected.

2. Do subcutaneous cysts require surgery, and can they be removed from the scalp?
While many subcutaneous cysts are harmless and may not require treatment, surgical removal is often recommended if the cyst is causing discomfort, is growing, or if there are concerns about infection. The procedure is usually straightforward and can be performed under local anesthesia. As for shaving your hair, it depends on the size and location of the cyst. In many cases, the surgeon may only need to shave a small area around the cyst to access it properly. However, this decision is best made in consultation with your surgeon.

3. Which medical specialty should you consult?
For a scalp bump like yours, the most appropriate specialists to consult would be a dermatologist or a general surgeon. Dermatologists specialize in skin conditions and can provide a thorough evaluation of the cyst, while general surgeons can perform the necessary surgical procedures if removal is indicated. If you have a primary care physician, they can also guide you to the right specialist based on your specific situation.

In addition to these answers, it’s important to monitor the bump for any changes. If you notice an increase in size, changes in color, or if it becomes painful, you should seek medical attention promptly. While most subcutaneous cysts are benign, any significant changes warrant further evaluation to rule out other conditions.

If you decide to pursue surgical removal, ensure that you discuss any concerns you have with your healthcare provider, including the potential need for hair shaving and the recovery process. Post-surgery, follow-up care is crucial to ensure proper healing and to address any complications that may arise.

In summary, while subcutaneous cysts on the scalp are common and usually benign, it’s essential to have them evaluated by a qualified healthcare professional. A dermatologist or general surgeon can provide the best guidance on whether removal is necessary and what the procedure entails.
