An Evaluation of the Performance of Current Morphea Subtype Classifications

Abstract

In this cross-sectional study of morphea subtype classification systems, the Padua criteria performed best in classifying patients into subgroups with cohesive demographic and clinical features, supporting its widespread use. However, they have ambiguities that might lead to misclassification, particularly in terms of generalized and pansclerotic morphea and descriptors such as morphea profunda. Consensus-based approaches are needed to address these ambiguities and develop a unified classification scheme.
