The patient was a rancher.The lesion's well-defined annular, scaly border raised suspicion of tineamanuum, which was confirmed by a potassium hydroxide evaluation. His occupationsuggested that livestock were the likely source of the infection. Chronichand eczema and psoriasis had also been considered in the differential.
