  • Abdominal hydatid cyst disease mostly involves the liver. Involvement of the pancreas as an isolated primary organ is rare accounting for < 2% of all systemic echinococcosis cases. It mostly involves the head of the pancreas. Symptoms depend on the location, size, and associated complications; therefore, it can have varied presentations including acute pancreatitis. On imaging, it can mimic other common pancreatic cystic lesions like pseudocyst or cystic neoplasm. Accurate preoperative diagnosis is usually difficult and requires a very high index of suspicion even in endemic areas. Herein, a case of primary isolated hydatid cyst of the pancreas that was initially diagnosed and managed as acute pancreatic pseudocyst is reported.

  • 섬모성 전장낭(ciliated foregut cut)은 드문 종양으로 주로 증례 보고 형태로 보고되었다. 이 양성 낭종은 대개 종격동에서 발견되어 전체 종격동 종양의 20%를 차지하지만 간 담도계와 췌장 주변 조직에서는 매우 드물다. 현재까지 췌장의 전장낭에 대한 영문 보고는 전 세계적으로 20건 정도이다. 저자들은 29세 여성에서 췌장 미부에 발생한 섬모성 전장낭의 사례를 초음파, 컴퓨터단층촬영, 자기공명영상 소견들과 함께 제시하고 문헌을 검토하고자 한다.

  • Radiographic visualization of the pancreas is a difficult problem, but the direct visualization of the pancreas is possible by the injection of the amino-acid methionine tagged with $selenium^{75}$75 ($Se^{75}$). In order to know the diagnostic value of pancreas scanning, scans were performed on 23 cases using $selenium^{75}$-selenomethionine. These cases were also given egg white, probanthine and morphine. 1. Good visualization of the pancreas scanning was observed on 19 cases, presumably with normal pancreas. 2. A case which showed diffusely decreased uptake on pancreas scanning was proven to have lesions in the bile duct and the gall bladder. 3. Of those two cases which showed localized cold area, one had pancreas cyst and the other one was not explored. 4. A case which showed no visualization of the pancreas was proven to have pancreatic carcinoma. 5. Two cases which showed widened duodenal loop by upper gastro-intestinal series revealed normal pancreas scanning, and no pancreatic disease was found in both cases.

  • Pancreatic lymphoepithelial cysts (LECs) are rare pancreatic cysts with squamous epithelial lining surrounded by dense lymphoid tissue. A preoperative diagnosis of LECs is difficult due to imaging diversity and inadequate documentation because of their rarity. We present a case of surgically confirmed pancreatic LEC with magnetic resonance imaging (MRI) findings as heterogeneous signal intensity on T2-weighted images with multiple septa-like structures, slightly hypo-signal intensity on T1-weighted images, and thin-wall enhancement on dynamic contrast images. LECs are benign lesions without any malignant potential. Therefore, the inclusion of LEC in the differential diagnosis of cystic pancreatic lesions may reduce unnecessary surgical procedures.

  • Congenital dilatation of the common bile duct (choledochal cyst) is an uncommon disease. Although the etiology is unknown yet, various theories such as distal obstruction of the common bile duct, congenital weakness of the duct and anomalous union of the pancreaticobiliary duct have been offered to explain the occurrence of choledochal cyst. Thirty - six cases of choledochal cyst over 22 years were analyzed clinically and classified according to Todani's classification and Kimura's anomalous union of pancreaticobiliary duct type. Todani type 1 consisted with 22 cases which were subdivided into 19 cases of type Ia, 1 case of type Ib and 2 of type Ic. Type IVa consisted with 14 cases including one case of Caroli's disease. There were 25 type BP cases and 10 type PB cases and 1 normal pancreatobiliary junction. Serum alkaline phosphatase was increased significantly in almost all cases. Seven patients (19.4%) had associated congenital anomalies such as double gallbladder, left - sided gallbladder, common bile duct web, biliary atresia, accessory hepatic duct, heterotopic pancreas, cleft lip and 2 cases of intestinal malrotation. All patients underwent cyst excision and Roux - en - Y hepaticojejunostomy and cholecystectomy. There was one death due to methicillin resistant Staphylococcus aureus sepsis.

  • Branchial cleft cysts typically are characterized as lateral swellings anterior to sternocleidomastoid muscle in upper third of the neck. However, cysts have been reported in unusual location such as the thymus, oral cavity, parotid gland, pancreas, and thyroid. Perithyroidal branchial cleft cysts are also rare and preoperative diagnosis is very difficult. Recently we have experienced a case of intrathyroidal branchial cleft cys and a case of perithyroidal branchial cleft cyst, which were diagnosed preoperatively as the parathyroid cyst. So, we report these two cases with review of the literatures.

  • Although cerebellar hemangioblastomas are histopathologically benign, they yield a degree of malignant clinical behavior in long-term follow-up. We present two cases of long-term progression of renal cell carcinoma, which had been diagnosed as renal cysts during treatment for cerebellar hemangioblastoma. A 14-year-old male with von Hippel-Lindau disease was admitted for a cerebellar hemangioblastoma with multiple spinal hemangioblastomas and a renal cyst. After primary total resection of the cerebellar hemangioblastoma, the patient required two further surgeries after 111 and 209 months for a recurrent cerebellar hemangioblastoma. Furthermore, he underwent radical nephrectomy as his renal cyst had progressed to renal cell carcinoma 209 months after initial diagnosis. A 26-year-old male presented with multiple cerebellar hemangioblastomas associated with von Hippel-Lindau disease and accompanied by multiple spinal hemangioblastomas and multiple cystic lesions in the liver, kidney, and pancreas. He underwent primary resect'lon of the cerebellar hemangioblastoma in association with craniospinal radiation for multiple intracranial/spinal masses. Unexpectedly, a malignant glioma developed 83 months after discovery of the cerebellar hemangioblastoma. At the same time, renal cell carcinoma, which had developed from an initial renal cyst, was diagnosed, and a radical nephrectomy was performed. In the view of long term clinical course, cerebellar hemangioblastoma associated with von Hipple-Lindau disease may redevelop even after primary total resection. In addition, associated lesions such as renal cysts may also progress to malignancy after the passing of a sufficient length of time.

  • The purpose of this study was to determine the effects of duration and timing of glucocorticoid treatment on the expansion and differentiation of porcine neonatal pancreas cell clusters (NPCCs) into ${\beta}$-cells. After transplantation of NPCCs, the ductal cyst area and ${\beta}$-cell mass in the grafts both showed positive and negative correlations with duration of dexamethasone (Dx) treatment. Pdx-1 and HNF-3${\beta}$ gene expression was significantly downregulated following Dx treatment, whereas PGC-1${\alpha}$ expression increased. Pancreatic duct cell apoptosis significantly increased following Dx treatment, whereas proliferation did not change. Altogether, transdifferentiation of porcine NPCCs into ${\beta}$-cells was influenced by the duration of Dx treatment, which might have been due to the suppression of key pancreatic transcription factors. PGC-1${\alpha}$ plays an important role in the expansion and transdifferentiation of porcine NPCCs, and the initial 2 weeks following transplantation of porcine NPCCs is a critical period in determining the final ${\beta}$-cell mass in grafts.

  • Autosomal dominant polycystic kidney disease (ADPKD) is a common genetic disorder characterized by the formation of fluid-filled cysts in the kidney and progressive renal failure. Other manifestations of ADPKD include the formation of cysts in other organs (liver, pancreas, and spleen), hypertension, cardiac defects, and cerebral aneurysms. The loss of function of the polycystin -1 and -2 results in the formation of epithelium-lined cysts, a process that depends on initial epithelial proliferation. cDNA microarrays powerfully monitor gene expression and have led to the discoveries of pathways regulating complex biological processes. We undertook to profile the gene expression patterns of epithelial cells derived from the cysts of ADPKD patients using the cDNA microarray technique. Candidate genes that were differently expressed in cyst tissues were identified. 19 genes were up-regulated, and 6 down-regulated. Semi-quantitative RT-PCR results were consistent with the microarray findings. To distinguish between normal and epithelial cells, we used the hierarchical method. The results obtained may provide a molecular basis for understanding the biological meaning of cytogenesis.
