ABSTRACT
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

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.

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.

Thrombotic thrombocytopenic purpura (TTP) rarely may be seen in association with autoimmune processes such as scleroderma, rheumatoid arthritis, polyarteritis nodosa, Sj gren's syndrome, and systemic lupus erythematosusus (SLE). The diagnosis of TTP as a syndrome distinct from SLE may be challenging, because both processes may present with some or all elements of the classic pentad considered pathognomonic of the former: microangiopathic hemolytic anemia, fever, thrombocytopenia, neurological deficits, and renal abnormalities. We describe a patient with synchronous TTP and SLE, and review the literature.

Malignant fibrous histiocytoma(MFH) is a high grade soft tissue sarcoma, commonly occur in the retroperitoneum, extremities, head and neck in the patient with old ages. But it is very uncommon that MFH primarily occurs in the lung, and uncommon in young ages. We experienced a young male patient with primary MFH of the lung. The patient had huge masses on both lungs which were diagnosed as MFH by thoracoscopy-guided wedge resection of mass, so we could not perform operative management. And we tried 6 cycles of chemotherapy using ifosfamide, doxorubicin, dacarbazine. After chemotherapy, masses still remained in spite of decreasing sizes.

Relapsing polychondritis is a rare disease characterized by widespread destructive inflammatory lesions, involving cartilaginous tissue throughout the body. Commonly involved organs include the external ear, nose, joints, eyes, tracheobronchial tree, cardiovascular system and cutaneous tissues. Erythema nodosum or mesenteric panniculitis have sometimes been described in association with relapsing polychondritis, but cutaneous panniculitis is rarely reported in relapsing polychondritis. We report here a relapsing polychondritis patient who developed cutaneous panniculitis, which was resolved by corticosteroid therapy.
