Sebaceous Cysts, Nevus and Lipomas

Description

Sebaceous cysts are benign cysts in the form of bags that grow under the skin and which contain fat material of follicular origin. They normally appear in the scalp, face and back although they may grow in any part of the body.

Nevus (moles) are injuries initially benign pigmented on the skin. They are very frequent and normally appear in areas exposed to the Sun. They may be of different sizes, color and may or may not be bumpy.

Lipomas are benign tumors of fat located on the skin and underlying muscular tissue. They appear more frequently in the thorax, limbs and in the upper part of the head (occipital region).

Symptoms

Sebaceous cysts do not normally show symptoms unless they infect. This happens when they hurt, look red and feel warm when touching them.

Nevus show different sizes and do not hurt. The main symptoms for their resection are that they bleed, itch or change color and size.

Lipomas only hurt when they are in certain areas of the body and that is when they have to be removed.

Treatment

The only possible treatment in the case of suspicion of malignancy or when they are uncomfortable is surgical removal. Depending on the size of the cyst, nevus or lipoma they are removed with local anesthesia and do not require hospitalization.
