L72: Follicular cysts of skin and subcutaneous tissue
L72.0: Epidermal cyst
Every hair is anchored in a small bulb, the hair follicle. This condition causes fairly large cysts filled with solid material to develop around these small hair follicles. The cysts can then be seen or felt as small papules or large nodules of a few centimeters.
The papules or nodules are mainly found on the upper body or on arms and legs. However, they can also appear on other areas of the skin.
