Sebaceous cyst

What is Sebaceous cyst?

Sebaceous cyst meaning These cysts are typically harmless, slow-growing bumps under the skin. They often appear on the scalp, face, ears, trunk, back, or groin area. They can arise from a ruptured follicle associated with acne, or be seen in a sebaceous duct that doesn't grow correctly, or from trauma to the area. Sometimes they develop without clear explanation. The cysts usually contain keratin, lipid, and other skin particles. Cysts can remain stable or progressively grow. Sometimes they will become inflamed or suddenly rupture. This poses a risk for infection.
