Corticosteroids can sensitize patients when used orally, parenterally, or intralesionally. We report delayed-type hypersensitivity to intralesional sterile triamcinolone acetonide suspension USP (Kenalog-40), which is rarely reported in the literature.

A 60-year-old woman presented for treatment of an 18-cm sternal hypertrophic scar. Treatment of this scar with an intralesional corticoid 3 years earlier had resulted in erythema and pruritus along the entire length of the midline scar approximately 12 to 18 hours after injection. The reaction resolved in approximately 3 weeks without treatment.Because of the earlier reaction, a test dose of 0.2 mL of intralesional sterile triamcinolone acetonide suspension USP (Kenalog-40) was injected in a 2-cm chest tube scar inferior to her sternal scar.

She denied any previous contact allergies. She had
