Benign ear cyst or tumor

Alternate Names : Osteomas, Exostoses, Tumor - ear, Cysts - ear, Ear cysts, Ear tumors

Definition

Benign ear cysts are noncancerous lumps or growths in the ear.

Overview, Causes, & Risk Factors

Sebaceous cysts are the most common type of cysts seen in the ear. They are bulging, sac-like collections of dead skin cells and oils produced by oil glands in the skin.

They commonly occur:

Behind the ear
In the ear canal
In the earlobe
On the scalp

The exact cause is unknown, but cysts may occur when oils are produced in a skin gland faster than they can be released from the gland.

Benign bony tumors of the ear canal (exostoses and osteomas) may be caused by excess growth of bone. Repeated exposure to cold water may increase the risk of benign tumors of the ear canal.
