The Dorsal Hand: An Extremely Uncommon Site for a Pilar Cyst

Pilar cysts, also known as trichilemmal cysts, are benign proliferations originating from the outer root sheath of hair follicles [1]. Clinically, they present as firm, mobile, subcutaneous nodules with smooth overlying skin [2]. Pilar cysts are most commonly found in middle-aged female patients (age 31-60) [2,3]. It is estimated that they account for approximately 24% of cutaneous cysts and occur in about 5-10% of the population [2,3].
