title: Clinical features of hidradenitis suppurativa and Crohn disease: what do these two entities have in common?
abstract: Hidradenitis suppurativa (HS) and Crohn disease (CD) are chronic, recurrent inflammatory diseases. They share certain clinical characteristics and flares are common in both. Both entities are usually diagnosed between the second and third decades of life and share risk factors such as smoking and overweight. In CD, as in HS, acute untreated episodes of inflammation can lead to sequels such as abscesses, fistulas and stenosis. Consequently, early management is of the utmost importance. Some patients have both diseases. The estimated prevalence of SH in CD patients is 12.4%-17.9%, while the prevalence of CD in HS patients is around 3%. The presence of HS in patients with inflammatory bowel disease (IBD) is associated with an earlier onset of IBD and with more frequent need for anti-TNF-alpha therapy and surgical resection.
