Plaques on dorsal hands & arms

Destructive therapy. Cryotherapy with liquid nitrogen or electrocautery may be used to destroy plaques. This approach may be used with or without pharmacotherapy.¹¹

Our patient. Because chromoblastomycosis is rare in North America, we consulted with a dermatologist who worked in an endemic area. Our patient was also seen by an infectious disease specialist. For 9 months, she took oral terbinafine 500 mg/d and itraconazole 200 mg/d. Initially, the patient experienced modest improvement in the largest plaques, but they didn’t clear completely. Smaller lesions cleared with cryotherapy but new lesions developed on her ears. The patient’s lesions finally cleared after 12 months of therapy; 2 repeated cultures were also negative.
