Examination of a skin scraping prepared with 10% potassium hydroxide revealed pigmented, thick-walled, multicellular structures known as Medlar bodies (see image), a finding that suggested chromoblastomycosis, a chronic, subcutaneous mycosis that can develop at sites of skin trauma.

Daily treatment with 400 mg of oral itraconazole was initiated and continued for 1 year, with slight abatement of the lesions. Further treatment with cryotherapy is planned.
