Brief Report

Abstract: Intralesional Kenalog (triamcinolone) injection is a useful treatment for several skin conditions. Although dermal deposition of triamcinolone has been described in the literature, histopathologic findings of foreign body reactions to it have seldom been reported. Here, we describe a case of a granulomatous reaction to the intralesional injection of triamcinolone acetonide in the treatment of nodulocystic acne.
