A male patient in his 40s presented to the emergency department with 6 months of a gradually worsening, extremely pruritic eruption. He first noticed this eruption while traveling to the US from Bangladesh through Central America. Before presentation, he was prescribed topical ketoconazole and fluconazole by a primary care physician without resolution. Physical examination was notable for large, annular, scaly, and erythematous plaques in the axillae () and legs extending from the groin. Involvement of the chest surrounding the areola was also noted (). A fungal culture was collected, the results of which demonstrated mold. Sequencing of the internal transcribed spacer (ITS) region confirmed a diagnosis of tinea corporis and cruris due to Trichophyton indotineae.
