Spontaneous Infarction of fibroadenoma of the breast is very uncommon and may lead to difficulties in clinical and pathological diagnosis. Most reported cases occured in young women during pregnancy or lactation. This report describes imprint cytologic features of an infarcted fibroadenoma in a 19-year-old young woman without evidence of pregnancy. The smears revealed many individually scattered degenerated or necrotic epithelial or spindle stromal cells and naked nuclei on dirty necrotic background. A few sheets of cohesive uniform epithelial cells and a few fragments of stromal cells were also present. Most of the epithelial cells had pyknotic and hyperchromatic nuclei, however, cellular atypism such as pleomorphism, prominent nucleoli or mitosis were not present. Though the necrotic ductular and glandular outline of this case may bear a superficial resemblance to adenocarcinoma, obvious cytologic atypia or mitosis, even in the necrotic areas, were not present.

This study was performed to evaluate the effect of aging and thermal cycling on the biaxial flexure strength of four commercially available veneering resin composites for crown(Dentacolor : DC, Artglass : AG, Esternia : ET and Targis : TG). Disc specimens were fabricated in a teflon mold giving 12mm in diameter and 1mm in thickness. All samples were divided into 4groups. Group 1 was dried in a dessicator at 25degrees C for 30 days. Group 2 was immersed in distilled water at 37degrees C for 30 days. Group 3 was immersed in distilled water at 65degrees C for 30 days. Group 4 was subjected to 10,000 thermal cycles between 5degrees C and 55degrees C, and the immersion time in each bath was 15 seconds per cycle. Biaxial flexure test was conducted using the ball-on-three-ball method at the cross head speed of 0.5mm/min and fracture surfaces were observed with scanning electoron microscope. The results obtained were summarized as follows ; 1. Weibull modulus values, except for the AG group, decreased after thermal cycling treatment. 2. Biaxial flexure strength values of aging group at 37degrees C were th lowest in all sample groups. Except for the DC group, strength values were significntly decreased for the drying group. 3. After thermal cycling test, the highest value of biaxial flexure strength of 188.8 MPa was observed in the ET group and the lowest value of 73.2 MPa was observed in the DC group. The strength values showed the significant differences in each group (p<0.05). 4. Observation of surfaces after thermal cycling test revealed the ditching in the part f surrounding large fillers.

Liver is generally known as an organ which is most commonly involved by the metastic tumors. According to the tendency of using fine needle aspiration in the diagnosis of hepatic tumors, the differentital diagnosis between hepatocellular carcinoma and metastatic carcinoma frequently has been a main issue in the poorly differentitated cases, especially to the pathologists of Korea, an endemic area of hepatocellular carcinoma. Until now the problem has been usually solved by the comparison of cytologic characteristics of their tumor cells but not by background cytologic features which rarely have been studied. We observed the background cytologic features helpful for the differential diagnosis through the analysis of 20 cases who had confirmed primary cancer and were diagnosed as metastatic carcinomas in the liver by fine needle aspiration cytology. Twenty cases included 9 adenocarcinomas, 7 spuamous cell carcinomas, 1 small cell carcinoma, 1 carcinoid, 1 adenoid cystic carcinoma, and 1 renal cell cacinoma. Analysis of background cytologic features revealed that 77% of adenocacinoma cases showed benign mesenchymal components and hepatocytes and spuamous cell carcinoma cases disclosed benign mesenchymal tissue (71%) and necrosis (57%). Remaining cases showed variable combinations of benign mesenchymal component, necrosis, hepatocytes, and bile duct epithelial cells. No case revealed atypical hepatocytic naked nuclei, a useful cytologic finding of hepatocellular carcinoma. In summary, the background cytologic features more commonly observed in metastatic carcinomas than in the hepatocellular carcinoma were benign mesenchymal components, hepatocytes, necrosis, and bile duct epithelium. The endothelial cells and hepatocytic naked nuclei, two relatively specific findings of hepatocellular carcinoma were not observed except for renal cell carcinoma. Above background cytologic features are thought to be helpful for the differential diagnosis between the hepatocellular carcinoma and various metastatic carcinomas in the poorly differentiated cases.

Serum alkaline phosphatase (AP) activity is elevated in hepatobiliary disease, bone disease, pregnancy and certain neoplasms. Recently we experienced marked elevation of serum AP activity after administration of albumin preparation in nephrotic patients who suffered from hypovolemic symptoms. So serum AP activity and the isoenzymes in the albumin preparations & patient's serum after the administration of albumin preparation were studied. Serum AP activity was significantly higher after administration of albumin preparation (318+/-101 IU/L) then before (123+/-43 IU/L). The predominant isoenzyme after administration of albumin was placental type, while liver and bone type was predominant before administration. AP activity in albumin preparation was high (2,133+/-1,410 IU/L) and the isoenzyme was mostly placental type. So we concluded that marked elevation of serum AP activity after administration of albumin was traced to the placental type AP isoenzyme in some albumin preparations which was manufactured from the plasma of placental origin. Elevated serum AP activity like these may lead to erroneous interpretation. Manufactures should notify alkaline phosphatase activity in albumin preparations of placental origin.
