RESUMEN
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. However, coronary angiography showed normal coronary arteries. Abdominal computed tomography revealed a left adrenal tumor of 6.7 × 6.8 cm. Paroxysmal fluctuation of blood pressure raised the suspicion of pheochromocytoma, which was further supported by elevated urine catecholamine levels. He underwent left adrenalectomy and pathological findings confirmed the diagnosis. CONCLUSION: Pheochromocytoma should be considered as part of the differential diagnosis in a patient with symptoms suggestive of both acute coronary syndrome and sepsis.

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. Double filtration plasmapheresis (DFPP) in which only a small amount of albumin supplementation is used may be a potential alternative to conventional apheresis interventions where clotting factor depletion is problematic. We report a case of a patient with Graves' disease complicated with intravenous immunoglobulin responsive methimazole-induced agranulocytosis/hemophagocytosis who underwent successful preoperative DFPP treatment in preparation for thyriodectomy. In addition to conventional apheresis using FFP replacement, DFPP may offer an effective adjunct option in the management of hyperthyroid patients needing emergent surgical interventions.
