Interstitial granulomatous dermatitis with arthritis (IGDA) is a rare disease that was first described by Ackerman1 in 1993. Fewer than 70 cases have been reported in the literature,2 and specific therapies are not available. We report here a case of severe recalcitrant IGDA that was successfully treated with ustekinumab.
