Hidradenitis suppurativa and Crohn's disease: two cases that support an association.

Abstract

An association between Crohn's disease and hidradenitis suppurativa has been suggested. The presence of Crohn's disease generally precedes the diagnosis of hidradenitis suppurativa. We present two new cases in which hidradenitis lesions developed before Crohn's disease, suggesting an overlap and supporting an association. Furthermore, in one of these cases, treatment with infliximab resulted in marked improvement in both the Crohn's disease and hidradenitis suppurativa.
