A solitary bump just underneath the skin, which may be white or light in color. This kind of cyst is filled with thick white or yellow waxy material made up of keratin, sebum and skin debris. They are found on the trunk, face, neck and scalp. They can become inflamed and infected. Infected cysts become tender and red.

Symptoms

Small lump beneath the skin. Infected cysts: redness, tenderness, increased warmth over the cyst, grayish-white cheesy discharge from the cyst.

Tests & Diagnostics

A history and physical exam will be performed. This is diagnosed by its appearance. Occasionally it needs to be drained for the diagnosis to be certain.
