AbstractAbstract PDF
A primary thyroid lymphoma is rare among all types of thyroid malignancy. Usually, a thyroid lymphoma is associated with underlying chronic autoimmune thyroiditis. Recently, we experienced a primary thyroid mucosa-associated lymphoid tissue(MALT) lymphoma, with an incidental micropapillary thyroid carcinoma, but lacking evidence of autoimmune thyroiditis. A female patient visited our hospital for further evaluation of a rapidly enlarging, painless thyroid mass which had been stable for 8 years. Lymphocytic thyroiditis or a lymphoma was suspected from fine needle aspiration performed at another hospital. The thyroid function test and other routine laboratory tests were normal. The histopathological findings after a total thyroidectomy revealed a MALT lymphoma with a micropapillary thyroid carcinoma. There was no evidence of chronic autoimmune thyroiditis. This is, to the best of our knowledge, the first case report of a MALT lymphoma arising from the thyroid gland without evidence of chronic autoimmune thyroiditis in Korea

AbstractAbstract PDF
Fifteen percent of patients with Cushing's syndrome could be accompanied with nonpituitary tumors that secrets ACTH-the ectopic ACTH syndrome. Among them, bronchial carcinoid is one of the rare causes of the ectopic ACTH syndrome. We experienced a 60-year-old woman who showed conditions of weight gain, generalized edema, hypokalemia, diabetes mellitus, and right middle lung mass. Histologically, the tumor was diagnosed with bronchial carcinoid and was confirmed as an ectopic ACTH syndrome through immunohistochemical staining of ACTH. After resection of the lung mass, blood sugar, electrolytes, generalized weakness, and blood pressure improved.

AbstractAbstract PDF
Vasoactive intestinal peptide(VIP) is a 28-amino acid peptide, which may cause secretory diarrhea by stimulating the production of adenylate cyclase. Neuroendocrine tumors, secreting vasoactive intestinal peptide (VIP), are almost always of a pancreatic in origin. However, a pheochromocytoma may produce several neuropeptides, containing VIP, as they are considered to be neuroendocrine tumors. A 57-year-old woman, who presented with chronic watery diarrhea, hypokalemia, weight loss and a left adrenal mass, is described. Histologically, the tumor was diagnosed as a pheoch-romocytoma, with ganglioneuronal differentiation, and was histochemically confirmed to produce a vasoactive intestinal polypeptide. A left adrenal VIP-producing pheochromocytoma was successfully resected. After surgery, her diarrhea subsided and the electrolytes, affected neuroendocrine hormone levels, blood pressure and blood sugar level were normalized.
