Abstract
Neutrophilic dermatoses are a wide group of disorders encompassing indolent to severely disabling conditions. A co-existence of two such conditions, pyoderma gangrenosum (PG) and subcorneal pustular dermatosis, necessitates a thorough investigation for IgA dysglobulinemia. We report a middle-aged woman who developed PG following 18 years of (undiagnosed) subcorneal pustular dermatosis, along with rheumatoid arthritis, a known association of PG.
