RESUMO
A 62-year-old man admitted to our outpatient clinic with two months of recurrent life threatening hypoglycemia episodes. He was diagnosed as malignant insulinoma with multiple metastases of liver and peripancreatic lymph nodes. Liver biopsy specimen was demonstrated grade 2 neuroendocrine tumor compatible with clinical and radiological results. He was followed under the treatment of continuous intravenous glucose infusion during the diagnostic procedures. He had a pancreatic lesion history measured 20 x 12 mm in diameter via the abdominal tomography examination approximately two years before the diagnosis. Unusual course of this case suggests the transformation of nonfunctioning pancreatic neuroendocrine tumor into functional insulin secreting tumor with metastases. The patient was found inoperable and started on chemotherapy. Arch Endocrinol Metab. 2015;59(3):270-2.

Primary hyperparathyroidism due to ectopic parathyroid adenoma is not infrequent. Primary hyperparathyroidism caused by unusual thymic nonadenomatous nonencapsulated parathyroid tissue has been reported before. Both can cause unsuccessful neck explorations. Here we presented for the first time a patient with hyperparathyroidism due to ectopic parathyroid adenoma concomitant to the presence of thymic nonadenomatous nonencapsulated parathyroid tissue.
O hiperparatireodismo primário devido a adenoma ectópico paratireoidiano não é raro. O hiperparatireodismo primário causado por tecido tímico paratireoidiano não edematoso e não encapsulado incomum já foi relatado anteriormente. Ambos podem levar à exploração cervical malsucedida. Apresentamos aqui, pela primeira vez, uma paciente com hiperparatireoidismo decorrente de um adenoma paratireoidiano concomitante com a presença de tecido tímico paratireoidiano não edematoso e não encapsulado.
