Carcinoid tumor of the lung and type-1 multiple endocrine neoplasia associated with persistent hypercalcemia: a case report.
The clinical and laboratory data, and histologic, electron microscopic and immunocytochemical findings of a carcinoid tumor of the lung associated with parathyroid hyperplasia and persistent hypercalcemia are described. The carcinoid tumor consists of uniform cuboidal cells with regular round vesicular nuclei and eosinophilic granular cytoplasm. The tumor cells were chromogranin and neuron-specific enolase positive. The CAT scan of the abdomen revealed an adrenal mass, 3 cm in diameter, and an enlarged body in the pancreas. Our patient is still suffering from hypercalcemia and renal colic, despite repeated parathyroid gland removal, and enucleation of the lung mass. Recent parathyroid scintigraphy with Tc revealed an enlarged parathyroid gland. The thoracic CAT scan is normal. We believe that our patient is suffering from multiple endocrine neoplasia type-1 with persistent hypercalcemia due to hyperparathyroidism.
