Dokuz-Aylık İnfantil Olguda Saçlı Deride Kalıcı Halka Şekilli Alopesi.

Halo scalp ring describes an annular scalp alopecia that arises perinatally and may present as a temporary and non-scarring alopecia or as a permanent hair loss. Herein, a-9-month old boy with a 3-months history of band like alopecia that encircled the posterior aspect of his head was presented. This case was remarkable with the presence of the history of cesarean section without any perinatal complications, and the presence of a non-temporary, late onset, ring shaped hair loss. We present this case to focus on this rare neonatal hair disorder and to discuss the possible differential diagnoses, approach and counseling to an infant with an acquired band like localized alopecia.
