The correct answer is  Answer A. ActinomycetomaMycetoma, commonly known as Madura foot, is a chronic, localized, slowly progressive, granulomatous infection of the deep dermis and subcutaneous tissue caused either by fungi (eumycetoma or implantation mycosis) or by aerobic actinomycetes (actinomycetoma). The presence of actinobacteria was confirmed on punch biopsy in this case. The patient responded to treatment with amikacin and trimethoprim-sulfamethoxazole.
