Different Phenotypes of Hidradenitis Suppurativa.

Hidradenitis suppurativa (HS) is a chronic inflammatory disorder with a heterogeneous phenotype. HS is a recurrent, fluctuating disease with various natural histories. Its phenotypes have been associated with responses to therapy; however, more studies about treatment response are needed, as is evaluation of biomarkers, before conclusions can be reached. This article provides a scoping review of HS phenotypes reported in the literature, with the hope that the results may offer insights for a more individualized approach to treatment.
