Sebaceous cyst on the neck of a man made hair cutting difficult and risky. It had been removed by simple surgery (excision) and the wound was photographed before it could heal.. The cysts are smooth to the touch, vary in size, and are generally round in shape. Sebaceous cysts form when the secretory (sebaceous) glands associated with hair follicles become blocked.
