Guide To The Common Types Of Cysts

Epidermoid Cyst

An epidermoid cyst, one of the most common and slowest growing types, is a small and hard lump that develops under the skin. This type of cyst won't cause symptoms, and almost none are cancerous. The most common places for an epidermoid cyst to form are the head, back, neck, genitals, and face. These cysts have a size range that's typically anywhere from a quarter-inch at the smallest to two inches in diameter at the largest. The appearance tends to be a small bump, and the color is generally yellow or tan. The fluid inside is smelly and thick. One important note is an epidermoid cyst doesn't cause pain, so if individuals do experience pain when touching the cyst, it's not an epidermoid type. Generally, epidermoid cysts can be ignored. These cysts are most often caused by keratin buildups in the skin. Keratin is a naturally occurring protein, but it can become trapped below the skin if a hair follicle or skin cell is damaged. Excessive sun exposure, HPV infection, acne, and skin injuries are all common causes.
