Answer

True epidermal inclusion cysts result from the implantation of epithelial elements in the dermis. Certain injuries, especially of the crushing type, have been associated with subungual or terminal phalanx epidermoid cysts. A crush injury sustained from slamming a car door on a digit is frequently reported. Any surgical procedure can theoretically result in epidermoid cysts. Reports describe the formation of multiple epidermoid cysts after rhinoplasty, breast augmentation, and liposuction. [31] The use of dermal grafts, myocutaneous grafts, and needle biopsies has also been associated with the formation of epidermoid cysts.
