Riedels thyroiditis is a rare variant of thyroiditis that is characterized by replacement of the normal thyroid parenchyma by extensive fibrosis. Typically, the thyroid is diffusely involved and a painless, hard anterior neck mass shows clinical features similar to those of anaplastic thyroid carcinoma, that is, a rapidly enlarging, hard, fixed thyroid mass and symptoms such as dysphagia, dysphonia, and dyspnea. We encountered a case of Riedels thyroiditis in a 41-year- old female patient with a longstanding benign thyroid nodule for 6 years; she subsequently presented with a rapidly growing, hard, fixed, thyroid mass mimicking anaplastic thyroid cancer. The clinical features were indistinguishable from those of anaplastic transformation, but open biopsy excluded anaplastic thyroid cancer. After surgery, the final diagnosis of Riedels thyroiditis was made based on typical microscopic findings and immunohistochemical studies. We have reported this case and reviewed the related literature. (Korean J Endocrine Surg 2006;6:98-101)

Carcinoid tumors arising in the extrahepatic bile duct are very rare, accounting for only 0.2%~2% of all gastrointestinal carcinoid tumord. We experienced one case of a carcinoid tumor in the common bile duct. A 43-years-old man was unexpectedly found to have a carcinoid tumor of the common bile duct. This patient had no obstructive jaundice, yet we thought that this tumor was a clinically malignant tumor, so we performed pylorus preserving pancreatoduodenectomy. Pathologically, an ill-demarcated mass that measured 1.5x1.5cm in size had invaded into the pancreas. Immunohistochemically, the mass was founded to be chromogranin, synaptophysin and CD56 positive. The patient who underwent curative resection is alive and disease-free at time of this publication. This report also reviews the relevant literature on carcinoid tumors in the common bile duct.

Of the various anomalies of the biliary system, a double common bile duct (DCBD) is extremely rare. According to a report by Boyden, the first case of DCBD was reported by Vesalius in 1543, with few additional case reports since 1986. Cancer and Anomalous pancreatobiliary ductal union (APBDU) are the two of the most serious concomitant conditions. A 69-year-old female was admitted to our hospital with the complaint of jaundice. An abdominal computed tomography and percutaneous transhepatic cholangiography revealed a mass lesion at the distal common bile duct. The patient underwent Whipple's operation, and the operative finding showed a septum in the common bile duct, with a DCBD opening as a single duct into the ampulla of Vater. A histological examination showed an adenocarcinoma in the ampulla of Vater. Herein, a case of the ampulla of Vater cancer in a patient with a double common bile duct is reported, with a review of the literature.
