Congenital ichthyosis is associated with cutaneous infections in a case-control study of 2260 patients.

Evidence of congenital ichthyosis association with cutaneous infections is limited to case reports. We conducted a nested case-control study assessing congenital ichthyosis associations with cutaneous infections using a large national database. Compared with controls, patients with congenital ichthyosis had higher odds of onychomycosis, tinea corporis, verruca vulgaris, and tinea pedis.
