Abstract

Abstract: Tinea of vellus hair is an unusual form of superficial skin infection, with a distinct prognosis from ordinary tinea. We report a case of tinea of vellus hair in a 7‐month‐old infant. Infected hairs were observed by dermoscopy and scanning electron microscopy (SEM). Single nucleotide polymorphism (SNP) detection confirmed the pet cat as a source causing the infection. A literature review was performed to summarize the clinical characteristics of this form of infection.
