ABSTRACT
Neuroendocrine carcinoma (NEC) arising from the extrahepatic bile duct is extremely rare and commonly mistaken for cholangiocarcinoma. Therefore, NEC of the bile duct is difficult to diagnose preoperatively. Previously reported cases were resected with a diagnosis of cholangiocarcinoma and diagnosed with NEC after surgery. This paper reports an 84-year-old female with small-cell NEC of the extrahepatic bile duct, confirmed by a biopsy from an ERCP, with a review of the relevant literature. Contrast-enhanced abdomen computed tomography and magnetic resonance cholangiopancreatography revealed an approximately 1.7 cm enhancing intraductal mass in the proximal common bile duct with dilatation of the upstream bile duct. ERCP showed a long strictured segment in the proximal common bile duct with bile duct dilatation. A biopsy was performed at the site of the stricture. Histological examinations and hematoxylin–eosin staining showed the solid proliferation of small tumor cells with irregularly shaped hyperchromatic nuclei.Immunohistochemical examinations showed that the tumor cells were positive for CD56 and synaptophysin. Small-cell NEC of the extrahepatic bile duct was confirmed based on the histology and immunohistochemistry findings. The patient and their family denied treatment because of the patient’s old age.
ABSTRACT
PURPOSE: This study is to identify the types of role awareness of home health care specialists working at medical institutions, to understand their role awareness correctly by grasping the quality of each type, and to provide useful help in the education of home health care specialists. METHOD: Q-methodology is used to objectify role awareness of medical institution specialists who may recognize situations differently according to their individual experience and comprehension based on the view of behavior. Q-classification was carried out on 30 home health care specialists working at medical institutions using 30 selected questions. Collected data were examined through factor analysis using QUANL PC program. RESULTS: Three different types of role awareness of home health care specialists working at medical institutions were identified. Type I is "educational-function-centered", Type II "patient-centered" and Type III "professional-service-centered". CONCLUSION: Regardless of these types, home health care specialists commonly had a high pride as a specialist and a sense of mission regarding themselves as important persons responsible for patients' health.
