Pilomatricoxas develop when cells harden and form a lump under the skin. The cells are similar to hair follicle cells.
Pilomatrixomas may be more common in some families. They may also happen with conditions that are inherited (genetic syndromes).
Here are the most common symptoms of a pilomatrixoma:
- A small, hard lump beneath the skin, usually on the face or neck
- The skin covering the lump looks normal or may have a blue hue
- The mass is usually painless, unless it becomes infected
The symptoms of a pilomatrixoma can be like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.
A pilomatrixoma is usually diagnosed based on how it looks and feels. Diagnostic tests may include:
- Biopsy. A sample of tissue is taken and looked at under a microscope.
- Imaging. X-ray, ultrasound, CT scan, or MRI may be done, but not always.
- A pilomatrixoma is a slow-growing, usually non-cancerous skin tumor of the hair follicle.
- It is most common on the face and neck.
- Treatment may include surgery to remove the lump.
- Before your visit, write down questions you want answered.
- At the visit, write down the names of new medicines, treatments, or tests, and any new instructions your provider gives you for your child.
- If your child has a follow-up appointment, write down the date, time, and purpose for that visit.
- Know how you can contact your child’s provider after office hours. This is important if your child becomes ill and you have questions or need advice.
