Introduction The imaging support of hidradenitis suppurativa (HS) has been increasing in the last decade due to the development of high-axial-resolution devices that can detect simultaneously and with high definition abnormalities of the skin and deeper layers. Nowadays, the spatial…
Introduction It is useful to consider the histological findings of hidradenitis suppurativa (HS) lesions in the context of populations at risk for HS to understand the clinical differences observed amongst these populations. HS disproportionately affects women, persons 18 to 29…
Introduction The average length of time from onset to diagnosis in hidradenitis suppurativa (HS) patients worldwide is 7.2 years. This unfortunate delay is partly because of the nonspecific nature of many HS lesions—inflammatory papules, nodules, pustules, abscesses, and scarring—which may…
Clinical Manifestation Morphology of Hidradenitis Suppurativa Lesions A key component of the diagnosis of an individual with hidradenitis suppurativa (HS) involves examining for the presence of typical HS morphology. The quantity and location of lesions indicate the severity of HS.…
Introduction This chapter will focus on the epidemiology of hidradenitis suppurativa (HS), examining the body of evidence available for estimating the incidence and prevalence of HS, and the distribution of HS by gender, age, and race. Epidemiology is a broad…
Introduction Hidradenitis suppurativa (HS) has a convoluted history with conflicting bodies of knowledge and a complicated pathogenesis. Since HS was first described in the 19th century, it has taken on various names and treatment strategies, leading to further confusion among…
