Skin manifestations help identifying different phenotypes of paediatric SAPHO syndrome

Semin Arthritis RheumPublished Retrospective cohort study

Authors' conclusion

our data suggest that two different skin phenotypes may be identified in SAPHO: the first is constituted by prepuberal females with PPP and a prevalent osteoarticular involvement, while the second by puberal males with a difficult-to-treat acne-HS.
