Pheochromocytoma mimicking both acute coronary syndrome and sepsis: a case report.

Objective: To present an atypical manifestation in a patient with pheochromocytoma.

Clinical Presentation And Intervention: A 48-year-old man presented with chest pain, fever and leukocytosis. Elevated cardiac biomarkers and diffuse ST-T abnormalities on electrocardiography suggested myocardial infarction.

Successful preoperative treatment of a Graves' disease patient with agranulocytosis and hemophagocytosis using double filtration plasmapheresis.

Agranulocytosis is an uncommon but serious complication of Graves' disease under thionamide therapy. In some patients removal of circulating thyroid hormones and thyroid antibodies by plasmapheresis is an effective adjunctive therapeutic option. In perioperative settings, however, plasmapheresis may cause excess bleeding intraoperatively due to coagulation factor depletion unless fresh frozen plasma (FFP) products are used in the replacement fluid mix.
