Azathioprine‐induced S weet's syndrome: A case series and review of the literature

We present three patients with azathioprine‐induced S weet's syndrome ( AISS ) who attended our tertiary institution within a 12‐month period. Established associations exist between S weet's syndrome and some medications; however, to date links to azathioprine are tentative. While there are case reports of AISS , most have occurred in patients with inflammatory bowel disease ( IBD ), an underlying predisposition for Sweet's syndrome. Our case series adds to the evidence that the entity of AISS truly exists independent of confounding factors such as concurrent IBD .
