Tinea cruris and tinea corporis masquerading as tinea indecisiva: case report and review of the literature.
J Cutan Med Surg 2015 Mar-Apr; 19(2):171-6JC

Abstract

BACKGROUND

Tinea indecisiva is characterized by concentric scaly rings simulating tinea imbricata but caused by dermatophytes other than Trichophyton concentricum.

OBJECTIVE

Tinea indecisiva has been rarely reported. We report a unique case and review of the previously reported cases, pathogenesis, and management.

METHODS

An adult Indian man developed extensive tinea cruris and tinea corporis with concentric rings of scaly lesions over the groin, buttocks, and thighs following the use of oral corticosteroids and antifungal-steroid cream for 3 months. Mycologic and immunologic studies were performed for diagnosis.

RESULTS

Diagnosis of tinea indecisiva was confirmed on the appearance of "ring-within-a-ring" lesions clinically and isolation of Trichophyton mentagrophytes var. interdigitale as the etiologic agent on mycologic testing. Intradermal testing with Trichophyton extract showed fluctuating hypersensitivity responses. Four-week treatment with daily oral terbinafine resulted in complete resolution.

CONCLUSION

Tinea indecisiva should be considered in a patient with tinea imbricata-like lesions with local immunosuppression caused by a non-concentricum dermatophyte.
