Autoimmunity-related granulomatous dermatitis in association with hepatitis

Grégory Szepetiuk et al. Case Rep Dermatol. 2012 Jan.

Abstract

Aim: Both interstitial granulomatous dermatitis (IGD) and palisaded neutrophilic granulomatous dermatitis (PNGD) are rare disorders typically associated with systemic autoimmune conditions. They probably represent different aspects of a disease spectrum encompassing the concept of autoimmunity-related granulomatous dermatitis (ARGD).

Case report: A 61-year-old woman presented with ARGD and autoimmune hepatitis. The clinical presentation suggested PNGD, while histopathology was consistent with IGD.

Discussion: The association of ARGD with autoimmune hepatitis is apparently a rare event. The present case shows that the clinicopathological correlation in ARGD does not always clearly fit with the classical presentations of IGD or PNGD.

Keywords: Autoimmunity; Granulomatous dermatitis; Hepatitis.
