title: Childhood tinea incognito caused by Trichophyton mentagrophytes var. interdigitale mimicking pustular psoriasis.
abstract: Tinea incognito refers to fungal infection whose clinical appearance is modified or aggravated by administration of systemic or topical corticosteroids. We report a case of pustular psoriasis-like tinea incognito caused by Trichophyton mentagrophytes var. interdigitale under topical corticosteroid therapy. Sequence analysis of the internal transcribed spacer 2 region, in addition to the D1D2 domain of the 26S ribosomal RNA gene, was helpful in identifying the fungal species.
