Generalized epidermolytic ichthyosis with palmoplantar hyperkeratosis

Epidermolytic ichthyosis (EI, OMIM 113800) is a rare autosomal dominant keratinization disorder that is caused by keratin 1 or 10 gene mutation. It can be classified clinically based on the presence of palmoplantar hyperkeratosis involvement and extent of skin involvement. The diagnosis is made by clinical and histopathological examinations that can be confirmed by genetic testing. We present a 2-year-old girl who presented with erythematous and thick scaling skin. Her condition began at birth as multiple flaccid blisters that would easily break into erosions. There was no history of similar condition nor consanguinity within her family. Skin examination revealed diffuse erythematous skin covered with thick scales and erosion, predominantly on her face, extremities, palms, and soles. The skin histopathology examination showed diffuse parakeratosis with vacuolar and granular degeneration within granular and spinous layers along the epidermis. She was diagnosed with generalized EI with palmoplantar hyperkeratosis based on the clinical and histopathological examinations. Clinical improvement was observed after a one-month treatment with mupirocin cream, sodium bicarbonate bath, and moisturizer after bathing.
