[Hashimoto's thyroiditis, idiopathic thrombocytopenic purpura (Werlhof's disease) and Steinert's dystrophia myotonica. A clinical case].

The authors report a rare association: Hashimoto's thyroiditis, thrombocytopenic idiopathic purpura (Werlhof's disease) and Steinert's myotonic dystrophia. The authors outline the fingerprints of each disease, report particular syndromes and compare that association to data of partially reviewed literature. They suppose a suggestive pathogenetic connection among these diseases, due to the coexistence of altered genetic, endocrine and autoimmune factors and consequently impaired cell membrane permeability.
