Pyoderma gangrenosum-like ulcers or pyoderma gangrenosum associated with antineutrophil cytoplasmic antibody-associated vasculitis

Abstract

We read with interest the report by Shakshouk et al. discussing cutaneous ulcers in setting of ANCA associated vasculitis (AAV). These ulcers were diagnosed as pyoderma gangrenosum (PG)-like ulcers, and authors aimed to differentiate these from classical PG. Characteristics of PG-like ulcers in association with AAV remain obscure, and differentiation from PG is not only challenging but perhaps also unnecessary.
