RESUMEN
Thyrotoxicosis is a rare clinical syndrome resulting from an exacerbation of hyperthyroidism, with various etiology and triggering factors. Its approach may be accomplished by blocking the synthesis of hormones, their secretion and/or inhibition of their peripheral action, besides treating the triggering factors. However, in refractory cases, plasmapheresis appears as an important option for treatment. We report a patient with Graves' disease who was admitted with thyrotoxicosis and signs of severe hepatotoxicity induced by propylthiouracil. Plasmapheresis was indicated, with the aim of rapidly reducing thyroid hormones in the preparation for total thyroidectomy.

A tireotoxicose é uma rara síndrome clínica decorrente da exacerbação do hipertireoidismo, de etiologia e fatores desencadeantes diversos. A abordagem terapêutica pode ser realizada por meio de medicamentos para bloqueio da síntese, secreção e/ou inibição da ação periférica hormonal, além de terapia dirigida aos fatores desencadeantes. Entretanto, em casos refratários, a plasmaférese surge como importante opção de tratamento. Relatamos o caso de um paciente com doença de Graves, internado com quadro de hepatotoxicidade grave por propiltiouracil, que evoluiu com tireotoxicose, sendo indicada plasmaférese para rápida redução dos hormônios tireoidianos, em preparo para a tireoidectomia total.
