Tinea Pseudo-imbricata.

A year male presented with multiple, itchy, erythematous, concentric plaques over groins since 3 months. Patient consulted a physician (non-dermatologist) and was prescribed topical preparation containing potent topical corticosteroids (clobetasol) in combination with clotrimazole. Initially there was a quick response in itching which prompted him to apply the product continuously for few weeks. After application of topical steroids morphology of lesion changed from annular to concentric plaques. We performed potassium hydroxide mount which showed hyphae and on culture Trichophyton rubrum was grown.
