We comment on the rarity of the clinical entity together with the nonspecificity of the routine diagnostic technique (EKG, X-ray, echocardiography study, routine laboratory, etc.) linked with the excellent gain of antibodies cardiac gammagraphy joined with viral serology, after the primary suspicion factor prior to the presence of skin lesions, fever and thoracic pain.
