Pilomatrixoma in Children
What is a pilomatrixoma in children?A pilomatrixoma (PY-lo-may-trick-SO-mah), also known as pilomatricoma, is a slow-growing, usually non-cancerous, skin tumor of the hair follicle. It is most common on the face and neck, but it may be on other parts of the body. A pilomatrixoma is usually a single lump, but occasionally, there may be more than one. Pilomatrixomas are more common in children and young adults than in older adults.
What causes a pilomatrixoma in a child?
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).
What are the symptoms of a pilomatrixoma in a child?
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.
How is a pilomatrixoma diagnosed in a child?
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.
How is a pilomatrixoma treated in a child?Treatment may include surgery to cut out the lump. Covering the area with skin from another part of the body may be needed, depending on the size of the lump.
What are the possible complications of a pilomatrixoma in a child?Most children do not face any serious complications. But pilomatrixomas can become cancerous in rare cases. Pilomatrixomas can also come back after they are removed.
When should I call my child’s healthcare provider?Call your child’s healthcare provider if you notice any skin lumps or masses.
