1. An epidermoid cyst is a small, slow growing, benign cyst most commonly found on the face, head, neck, back, or genitals.
2. A sebaceous cyst is found on the face, neck, or torso. It’s usually caused by trauma or damage to the sebaceous glands, such as from cuts or surgical wounds.
3. Most breast lumps (such as cysts) are noncancerous, but there are many possible causes for a lump in your breas
4. A ganglion cyst is a round, gel-filled lump of tissue that usually appears along tendons or joints, especially in the hands, wrists, ankles, and feet.
5. A pilonidal cyst is a common skin condition that forms in the cleft at the top of the buttocks. It typically occurs after puberty.
6. Ovarian cysts are fluid-filled sacs that develop on one or both of the ovaries. They may develop as a normal part of the reproductive cycle or be pathologic.

11. A perineural cyst is a fluid-filled sac that forms on the spine. Symptoms are rare. In these cases, it may cause pain in the lower back, buttocks, or legs.
