If you have an ingrown hair that has turned into a hard lump under the skin, it could be a pilomatricoma, which is a type of noncancerous skin tumor associated with hair follicles. However, it could also be an ingrown hair cyst, which occurs when the hair grows downward instead of upward and becomes trapped under the skin. Here are some details on these conditions:
Pilomatricoma
- Description: A type of noncancerous skin tumor associated with hair follicles. Pilomatricomas occur most often on the head or neck, although they can also be found on the arms, torso, or legs. A pilomatricoma feels like a small, hard lump under the skin. This type of tumor grows relatively slowly and usually does not cause pain or other symptoms.
- Positive: If a pilomatricoma is removed surgically, it tends not to grow back (recur).
- Negative: Pilomatricoma is an uncommon tumor. The exact prevalence is unknown, but pilomatricoma probably accounts for less than 1 percent of all benign skin tumors.

Ingrown hair cyst
- Description: An ingrown hair occurs when the hair grows downward instead of upward and becomes trapped under the skin. Ingrown hairs can cause cysts to develop. These lumps can resemble boils or other skin issues. This can range from a small, painless lump to a large, infected growth. If a doctor diagnoses it, they may call it an epidermoid cyst or a pilonidal cyst.
- Positive: Ingrown hairs are a common skin condition. They may appear anywhere hair grows on your body, but they commonly appear in places where you shave, tweeze or wax, especially your face, legs, armpits and pubic area. A good skin care routine helps prevent ingrown hairs from forming, while at-home treatments can help release the hair from underneath your skin and provide relief.
- Negative: Ingrown hairs can cause discomfort, pain, and infection if left untreated.
- Ingredients or materials: Not applicable.
Its important to see a healthcare professional for an accurate diagnosis and appropriate treatment.
