What tests examine a small lump at the back of the head?

Question

Hi doctor,

My niece has a small lump at the back of her head that has been there since childhood. It is under the skin, not visible, but can be felt by touch.

Sometimes, it causes mild pain when pressed. There has been no change in its size, no discolouration, and no symptoms like fever. Is this something normal, or should we consider any examination or test?

Kindly suggest.

Thanks.

Hi,

Welcome to icliniq.com.

I can understand your concern.

From what you have shared about your niece's lump at the back of her head, here is a professional overview: Most likely possibilities (benign):

Epidermoid cyst or sebaceous cyst: It is common, slow-growing, and painless unless inflamed. It feels round, smooth, and mobile under the skin.
Lipoma: A soft, fatty lump that is harmless and non-painful unless pressed hard.
Lymph node (reactive or scarred): Especially if there was an old infection nearby (like a scalp infection or cut), it can remain for years without growing or causing problems.
Dermoid cyst: It is congenital (from birth), firm, and commonly found near the scalp or head.
Sudden growth in size.
Persistent pain, even without touching.
Redness, warmth, or drainage (infection signs).
Neurologic symptoms such as dizziness, weakness, and headaches.
Family history of cancers or unusual masses.

Recommended steps:

Since it has been there unchanged for years, and she is not showing any worrying symptoms, this lump is most likely benign. However, for peace of mind and medical safety, I advise you to undergo an ultrasound or CT (computed tomography) scan to rule out any possible hidden ailment and provide the results.

Since there is mild pain, let her kindly take the following: Two tablets of Acetaminophen 500 mg for one week.

I hope this information will be helpful to you.

Thanks.
