Histologic Findings
The penetrating hair causes invagination of the epidermis with inflammation and intraepidermal abscesses. With penetration of the dermis, the epidermis grows down to try to ensheathe the hair, and severe inflammation, abscess formation, and a foreign-body giant cell reaction occur at the tip of the hair.
