Abstract

A 14-year-old girl who reported generalized scaling and hyperkeratosis since age 1 year presented with severe pruritus of several months' duration. Scabies mites were detected, and molecular genetic analysis subsequently revealed a rare pathogenic variant in the keratin 2 (KRT2) gene, confirming a diagnosis of superficial epidermolytic ichthyosis. Treatment with oral ivermectin led to complete remission of symptoms. Disorders of keratinization can mimic clinical signs of scabies, leading to a delay in diagnosis.

Keywords: KRT2; bullous; epidermolytic ichthyosis; keratin 2; keratinization disorder; scabies; superficial epidermolytic ichthyosis.
