• Resumen

  • The terms “palisaded neutrophilic and granulomatous dermatitis,” “interstitial granulomatous dermatitis,” and the subset “interstitial granulomatous drug reaction” are a source of confusion. There exists substantial overlap among the entities with few strict distinguishing features. We review the literature and highlight areas of distinction and overlap, and propose a streamlined diagnostic workup for patients presenting with this cutaneous reaction pattern. Because the systemic disease associations and requisite workup are similar, and the etiopathogenesis is poorly understood but likely similar among these entities, we propose the simplified unifying term “reactive granulomatous dermatitis” to encompass these entities.
