A 55-year-old woman received 10 intralesional injections of triamcinolone acetonide 40 mg/ml and 5-fluorouracil 50 mg/ml (1:9 ratio) once every 3–4 weeks, combined with cryotherapy (only in last four sessions) for her presternal keloid. Three weeks after the last injection, she presented with an itchy, erythematous, scaly plaque, circumferentially surrounding the elevated borders of keloid [Figure - 1]. A 10% KOH (potassium hydroxide) mount showed multiple branched septate hyphae. The dermatophytosis flared after treatment with terbinafine but responded to a combination of oral itraconazole and griseofulvin.

This case is probably explained by the cutaneous anergy caused by intralesional immunosuppressive injections in keloid, which became the site of onset of dermatophytosis.
