Atypical tuberous myxedema Jadassohn-Dössekker. Report of a case.

A 48-year-old male patient with atypical tuberous myxedema Jadassohn-Dössekker, characterized by nodules on both upper legs with mucin deposits, is described. Atypical tuberous myxedema Jadassohn-Dössekker can be classified together with lichen myxedematosus and scleromyxedema Arndt-Gottron as normothyrotic myxodermia. It can be distinguished from lichen myxedematosus only by the size of the lesions. The pathogenesis is unknown.
