Hidradenitis suppurativa (HS) is a chronic, inflammatory disease characterized 
by recurring abscesses, nodules, and fistulas predominantly in the area of the 
groin and axillae. The association between HS and Crohn's disease (CD) has 
already been documented. We report on a case of a patient with CD associated HS, 
refractory to multiple local and systemic agents.A complete resolution of both 
diseases was finally achieved after treatment with adalimumab. Our case report 
supports the co-occurrence of both diseases and suggests that adalimumab 
approved for CD might also be a safe and effective therapeutic option in the 
treatment of HS.
