A 24-Year-Old Man with Excessively Odorous and Itchy feet

The patient is a 24-year-old man who presents with excessive foot odor that he describes as “worse than anything I could have imagined.” He denies pain or burning, but reports that the soles of his feet itch occasionally. He also says his feet sweat heavily when he plays recreational ice hockey a few nights a week. Upon examination, several shallow rounded pits are found on the pressure-bearing areas of the soles.
