About this symptom
A lump beneath a child’s scalp may be a cyst or another condition. Appearance alone does not establish the diagnosis. A lump present since birth, growing or changing deserves clinical assessment.
What this means
A scalp lump is a symptom rather than a specific diagnosis. Superficial skin cysts, congenital dermoid lesions, inflammation and other usually benign conditions can look similar. Calling a lump a “cyst” before assessment does not establish its type. Materials provided by the clinic describe a scalp lump noted from birth, but the exact histological diagnosis in that case was not confirmed. It must not automatically be labelled an epidermoid, pilar (trichilemmal) or dermoid cyst.
Signs and concerns
Parents may notice a rounded nodule or small local swelling beneath the scalp. It may be present from birth or appear later, remain unchanged or gradually enlarge. Tenderness, redness, irritation and discharge are possible, although some lumps cause no symptoms at all. The combination of signs and examination findings matters more than any single feature.
Possible causes and distinctions
Epidermoid cysts, pilar or trichilemmal cysts, and congenital dermoid cysts differ in origin and typical presentation. Pilar cysts can occur on the scalp but are described more often in adults; a congenital scalp lump in a child should not be assumed to be one. Midline position, proximity to cranial sutures, depth and mobility are important when considering a deeper congenital connection.
Assessment and diagnosis
The clinician asks when the lump first appeared, whether it has changed and whether there has been inflammation or trauma. Examination assesses size, mobility, depth, overlying skin and precise location. Ultrasound is useful in selected cases but not mandatory for every scalp lump. When a congenital or deep connection is suspected, other imaging and specialist review may be needed before deciding on intervention.
Care and treatment
Management depends on the actual diagnosis. Some lesions can be monitored; others may require planned removal after suitable assessment. Surgery should not be promised from the location or the provisional word “cyst” alone. A doctor’s documented case does not by itself establish that a particular procedure is available at this clinic. Do not puncture, squeeze or drain a lump at home because this can cause infection, bleeding and tissue injury.
When urgent care is needed
Prompt medical review is needed if the lump grows quickly, becomes very painful, develops marked redness, pus or fever, or the child becomes unwell. If severe illness, seizures or impaired consciousness occur, call emergency services on 103 or 112. A congenital lump at the scalp midline or near cranial sutures also warrants timely planned assessment even without pain.

Frequently asked questions
Does every scalp lump in a child mean a cyst?
No. Cysts, inflammatory changes and other lesions can look similar. Its type cannot be reliably identified from a photograph or appearance alone; clinical assessment is needed.
Does a child with a scalp lump always need ultrasound?
No. The decision depends on the child’s age, the location, mobility, depth and behaviour of the lump. Ultrasound or other imaging may be appropriate when a deeper congenital lesion is suspected.
Is it safe to squeeze or puncture a scalp lump at home?
No. Squeezing or puncturing may cause infection, bleeding and tissue damage. It also does not clarify the cause or replace diagnosis.
