Tinea pseudomibricata due to Trichophyton mentagrophytes: a rare case report

Tinea pseudoimbricata is characterized by concentric scaly rings simulating tinea imbricata but caused by dermatophytes other than Trichophyton concentricum. We report a unique case of tinea pseudomibricata, its pathogenesis and review of previously reported cases. A 1.5-year-old baby developed concentric rings of scaly lesions over groins and buttocks following use of topical corticosteroids for 1 month. Mycological studies were performed to establish the diagnosis. Diagnosis of tinea pseudoimbricata was made on the basis of morphology of lesions and was confirmed by isolation of T. mentagrophytes on culture. Complete clinical and mycological cure was obtained with topical 1% sertaconazole given for 4weeks
