Pathogenic strains of Candida albicans, Cryptococcus neoformans, Staphylococcus aureus, Escherichia coli, Klebsiella pneumonia, Streptococcus pyogenes, Trichophyton rubrum,
Trichophyton concentricum, Alternaria alternata, and Curvularia lunata were used.
While most species of Trichophyton and Microsporum can cause Tinea capitis, it is interesting that Epidermophyton floccosum,
Trichophyton concentricum and Trichophyton interdigitale never cause Tinea capitis.
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.
Tinea imbricata is an anthropophilic dermatophytosis caused exclusively by Trichophyton concentricum that is primarily seen in individuals of pure race residing in primitive isolated conditions and often is associated with poor hygiene.1 The exact mode of inheritance is unknown.
Trichophyton concentricum is confined to South Pacific, Central and South America.
