Based on the clinical history provided in the consultation request, this presentation is classic for extensive dermatophytosis (Tinea corporis and Tinea cruris) complicated by prior topical steroid exposure.
Clinical Assessment
Topical Steroid Impact: "Lebrostone" (typically containing Clobetasol propionate, an ultra-potent topical corticosteroid) temporarily suppressed the itching and inflammation but likely caused Tinea incognito. Topical corticosteroids alter fungal morphology, thin the epidermal barrier, promote wider fungal dissemination (spreading to bilateral groins and inframammary folds), and cause marked skin burning/stinging.
Current Lesion Evolution: The transition of older lesions to dark brown/black with peeling represents post-inflammatory hyperpigmentation (PIH) and resolving epidermal scale as inflammation subsides, while the new ring-like lesions under the breast indicate active, spreading infection
