Pilar Cyst Information
A pilar cyst is a firm, subcutaneous, keratin-filled cyst originating from the outer root sheath of the hair follicle. Roughly 90% of pilar cysts are found on the scalp, with the remaining 10% occurring on the face, neck, back, and scrotum. The epithelium of the outer root sheath undergoes a different form of keratinization than cutaneous epithelium.
