A Case of Tinea pseudoimbricata Caused by Microsporum Audouinii

Tinea pseudoimbricata has morphological similarity to Tinea imbricata which is characterized by multiple concentric rings, but it is caused by dermatophytes other than Trichophyton Concentricum. We report a case of tinea pseudoimbricata caused by Microsporum Audounii that presented with multiple concentric scaly annular erythema. The most common clinical presentation of pseudoimbricata was tinea corporis followed by Tinea cruris. However, tinea imbricate-like lesions are very rare. Tinea pseudoimbricata is considered a unique sub-type of Tinea incognito which caused by inappropriate use of topical steroid. Both Fungal culture and microscopic findings confirmed Microsporum Audouinii infection in this case. The patient was treated with oral terbinafine according to culture and antifungal sensitivity testing at a dose of 250 mg/day for 8 weeks.
