Sebaceous cyst: Understanding the Condition

A sebaceous cyst is a non-cancerous, small lump under the skin, typically filled with a white, oily substance called sebum. It is usually harmless but can become inflamed or infected.

Causes

  • Blocked sebaceous glands
  • Trauma to the skin
  • 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
  • Genetics

Importance of Early Treatment

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