Risk Factors And Causes Of Earlobe Cysts

Abnormal Reaction To Skin Injuries

Sebaceous glands reside within the body’s skin. When a gland is blocked in some way, the sac containing the sebum generators fills with this material, inducing swelling and bursting of that sac. Trauma may also cause sebaceous cystic formation, inducing development along the margins of the wound or within the wound itself. An abnormal reaction to skin injuries may also be seen subdermally, when trauma and bruising causes hematoma or scarring or thickening in deeper tissues. These cysts may be palpable even when not visible at the skin's surface. Earlobe piercings, for example, are common, and these little traumas may allow bacteria to enter the wound, causing infection and swelling. Earring stems, worn to keep the initial earlobe wound open until it has adequately scarred for permanent use of earrings, may cause an allergic response in the body, and cystic development may be an unexpected outcome. Allergy responses may be induced by nickel or other earring materials, by bug bites, et cetera.
