- Swollen hair follicles
Symptoms
- Smooth, round lump under the skin
- Painless unless infected
- May ooze a foul-smelling substance if ruptured
Diagnosis
- Physical examination
- Ultrasound or MRI
- Biopsy (if needed)
Treatment
- Observation (if asymptomatic)
- Incision and drainage
- Surgical removal
Risk Factors
- Skin injuries
- Acne

Importance of Early Treatment
Early intervention prevents infection and discomfort. Surgical removal is often the most effective solution.
