Scabies incognito mimicking urticaria pigmentosa

Scabies is a common, extremely pruritic and contagious mite infestation caused by Sarcoptes scabiei var. hominis. Scabies in infants has a different clinical appearance from adults with the presence of more vesicles, pustules, and crusts; involvement of palms, soles, fingers, facial and scalp more frequently, and more inflammatory lesions. The diagnosis of scabies in infants can be delayed or misdiagnosed with other dermatoses due to secondary eczematization and impetiginisation, mistreated with topical steroids and not to suspect from scabies in infants. Herein, we present a 6-month-old boy diagnosed with scabies incognito by histopathological examination that mimics urticaria pigmentosa clinically. Copyright © 2018 by Türkiye Klinikleri.
