Generalized dermatophytosis in a patient with congenital ichthyosis

摘要

Ichthyosis is defined as a group of diseases with keratinization disorder and diffuse scaling with highly variable degree of involvement. According to our knowledge, coincidence of ichthyosis and dermatophytosis, which both are very common disorders, is a very rare event. We report a young man with congenital ichthyosis that histological analysis of his skin biopsies and direct smear revealed PAS positive fungi. He had used topical steroids for generalized scaling erythematous patches and plaques for long time.
