ISSN 0001-5555 “Self-healing” Langerhans’ cell histiocytosis (LCH), first reported by Hashimoto & Pritzker in 1973 (1), is a rare primary skin disorder that presents at birth or just after birth. It can be categorized based on the involvement of solitary or multiple sites and can be further classified as congenital or late-onset (2). Although more than 100 cases of self-healing LCH have been reported (3), solitary, late-onset, self-healing LCH is extremely rare (4–7). We herein report a case of solitary, late-onset, self-healing LCH and review previous reported cases.
