Deflazacort hypersensitivity: a difficult-to-manage case of systemic allergic dermatitis and literature review.

Management of corticosteroid (CS) hypersensitivity is not easy, and the choice of an alternative CS is difficult, owing to the high frequency of cross-reactions. Deflazacort has been reported to be a safe alternative in subjects with CS hypersensitivity (1), and reports of deflazacort hypersensitivity are rare (2–7). Here, we report a difficult-to-manage case of systemic allergic dermatitis caused by deflazacort.
