title: Neonatal Alopecia Due to Birth Trauma: Case Report and Trichoscopic Findings.
abstract: A 4-day-old boy was referred for evaluation of an oval patch of occipital alopecia associated with caput succedaneum and ipsilateral eyelid ecchymoses. Based on the history of a prolonged, difficult labor with vacuum-assisted delivery, the diagnosis of neonatal alopecia associated with birth trauma was made. Trichoscopy showed purple dots corresponding to blood extravasation and follicular ostia. We also review the trichoscopic differential diagnosis of focal neonatal alopecia.
