Cystic nephroma (CN) is a benign cystic neoplasm composed of mixed epithelial and stromal elements. Less than 200 cases have been reported. We had a patient, a 41-year-old woman, who had a huge typical CN. The patient was admitted for a right renal mass that was found incidentally. On laparaoscopic right nephrectomy, there was an encapsulated 7 cm multilocular cystic mass at the upper pole. Microscopically, the cystic wall was lined by a single layer of low cuboidal or hobnail epithelium without a solid area. The thin septa were composed of bland, ovarian type spindle cells. The main differential diagnoses were mixed epithelial and stromal tumor (MEST), low grade multilocular renal cell carcinoma, and tubulocystic carcinoma. The results of immunohistochemical staining were cytokeratin 7/19(+/+) and CD10(-) in lining epithelium, estrogen receptor/progesterone receptor(+/+) in stromal cells. After surgery, she was free of recurrence for 10 months. We report this rare case and compare it with other cystic renal tumors, especially MEST.

PURPOSE: Recently, vancomycin-resistant enterococci (VRE) have become one of the major nosocomial pathogens in Korea. However, there have been few studies on the epidemiology of VRE colonization among neonates. In this study, we investigated the prevalence of VRE colonization, risk factors for VRE, and how to control the spread of VRE infection in the Neonatal Intensive Care Unit (NICU) of Pusan National University Hospital (PNUH). METHODS: We retrospectively reviewed medical records of 192 neonates who were admitted to the NICU of PNUH from March 2006 to March 2007. Surveillance cultures from rectal swabs for detecting VRE were obtained weekly during the study period. We analyzed the prevalence of VRE and various risk factors. RESULTS: The rate of VRE colonization among NICU patients was 25% (48/192). Thirty five of these VRE colonized patients were transferred to the NICU from other local hospitals. Compared with the non-VRE group, the risk factors associated with VRE colonization were lower birth weight, congenital heart disease, applied mechanical ventilation, use of a central venous catheter, chest tubing, a history of surgery, and use of antibiotics. CONCLUSION: VRE colonization among patients admitted to the NICU is rapidly increasing. Monitoring and managing premature neonates from the beginning of the birth process, avoiding many invasive procedures, avoiding antibiotics such as vancomycin and third generation cephalosporin are important for preventing the emergence and spread of VRE colonization in the NICU.

Heterotopic pregnancy is the coexistency of intrauterine and extrauterine pregnancy. The incidence of heterotopic pregnancy is about 1 to 30,000 pregnancy in a natural cycle. However, the frequency of heterotopic pregnancy has steadily increased because of rising incidence of pelvic inflammatory disease, pelvic surgery and the development of ovulation induction and assisted reproduction. Because heterotopic pregnancy is difficult to diagnose and it has high morbidity and mortality rate, one should always take this into consideration and should conduct careful and thorough gynecologic evaluation. We have experienced a case of heterotopic pregnancy in a 29-year old woman who presented with acute abdominal pain in a natural cycle and report this case with a brief review of literature.

A clinico-pathologic study with an immunohistochemical examination for c-erbB-2 expression in 54 cases of ductal carcinoma in situ and 16 cases of Paget's disease of the breast was performed. c-erbB-2 oncoprotein overexpression was observed in 45% (24/54) and 88% (14/16) of ductal carcinoma in situ and Paget's disease, respectively. The overexpression of c-erbB-2 oncoprotein was significantly correlated with the nuclear grade of tumors and inversely with the status of the estrogen receptor. c-erbB-2 was positive in 4 out of 5 patients with metastasis to axillary lymph nodes and 3 out of 4 patients who died of the disease. Prognostic significance of c-erbB-2 oncoprotein in ductal carcinoma in situ was highly suggested. The expression of c-erbB-2 oncoprotein in Paget's disease was well correlated with coexisting infiltrating or in situ ductal carcinoma. The high positive rate of c-erbB-2 oncoprotein in ductal carcinoma with Paget's disease could be understood with a recent hypothesis that c-erbB-2 oncoprotein is involved in promotion of cell motility and the spread of carcinoma cells.
