Pancreatic neuroendocrine tumors (NETs) frequently accompany metastatic lesions, and hepatic metastases are the most common of all NETs. However, another disease may also be present, potentially leading to misdiagnosis and metastasis of a NET. Clinicians should consider an active diagnostic evaluation for metastatic lesions, including liver biopsy, particularly when the hepatic lesion has distinct characteristics from the primary tumor. In our case, the patient had both a pancreatic NET and a primary hepatic lymphoma. She underwent laparoscopic distal pancreatectomy with splenectomy, and progress of the primary hepatic lymphoma was observed in the outpatient clinic.

Purpose:The objective of this study is to find out physical properties and the flexural strength changed by the low temperature degradation of the block which is needed to make bio-prosthetic dentistry which is better than feldspar affiliated ceramic made by building up ceramic powder and also to apply this to the clinical use of zirconia monolithic all-ceramic crown.Methods: Flexural strength of each sample was evaluated before and after the Low Temperature Degradation ,and physical properties of the Tetra Zirconia Block containing 3mol % was evaluated as well.The average and standard deviation of each experimental group were came out of the evaluation. Statistical package for social science 18.0 was used for statistics.Results: The average density of the monolithic all-ceramic crown was 6.0280 0.0147g/cm, the relative density was 99.01 %. When the sample was sintered at 1480 the diameter of average particle was 396.62 33.71nm. All the samples had no monolithic peak after XRD evaluation but only had tetragonal peak. There were statistically significant differences in the result of flexural strength of the samples evaluated after and before the low temperature degradation, the flexural strength before the low temperature degradation was 1747.40 ßÁ, at the temperature of 130 the flexural strength after the low temperature degradation was 1063.99 (p<0.001). There was statistically significant difference in the result of strength of 1020.07 after the low temperature degradation at the temperature of 200 (p<0.001).Conclusion: The block which was made for this evaluation possesses such an excellent strength among dental restorative materials that it is thought to have no problems to use for tetragonal zirconia polycrystal.[Abstract] 83
