Lichen myxedematosus (LM) is a rare, chronic idiopathic disorder characterized clinically by waxy, closely set papules and histopathologically by diffuse dermal mucin deposition and fibroblast proliferation. The most recent classification of LM was proposed in 2001; however, it seems to be complex, confusing, and imprecise. Herein, we present seven cases of LM to evaluate the validity of the current classification, to propose new diagnostic criteria and classification, and to suggest a clinically relevant severity grading system for this rare disorder.
