Unraveling the Heterogeneity of Hidradenitis Suppurativa with Phenotype Schema.

One of the major challenges faced with hidradenitis suppurativa (HS) is the variability in manifestations and treatment responses. Cazzaniga et al. (2020) conducted a cross-sectional study and latent class analysis to explain disease heterogeneity and formulate HS phenotypes. HS phenotypes might be useful for disease or treatment outcomes. Future studies should assess rater reliability and predictive validity for outcomes such as treatment response or disease progression.
