Occipito-Linear and Temporo-Fronto-Parietal Alopecia as a Form of Transient Hair Loss in Infants

Abstract

Neonate’s temporal triangular alopecia, transient neonatal hair loss (TNHL) or neonatal occipital alopecia (NOA) is observed in the occipital of infants at the second to third months after birth in a band–like shape or oval alopecia patch. We present two infants with hypotrichosis over the occipital region and fronto-temporo-parietal region in triangular form bilaterally, based on the clinical hypotrichosis distribution pattern and trichoscopic features, with the exclusion of other alopecias. The diagnosis of occipito-linear and triangular fronto-temporo-parietal marginal alopecia was made accordingly. We also discussed the two different lesions in the presented case as a combined form of neonatal occipital alopecia.
