The National Cancer Institute offers a variety of patient education publications about coping with the effects of cancer and its treatment on everyday life, including materials for caregivers and family. Morphology and immunocytochemistry support the origin of the cells. The main purpose of this review is to summarize the accumulated evidence on serous malignant tumors and to clarify the unresolved issues. 11 In the gastrointestinal system, CD10 is expressed in colon and hepatocellular carcino-mas. Current nomenclature uses the term intrahepatic cholangiocarcinoma (IHCC) to define tumors arising from biliary epithelium in intrahepatic bile ducts above the level of the left and right main ducts ( Liver Cancer Study Group of Japan, 1990 ). The postoperative pathological diagnosis was small cell ovarian carcinoma of the pulmonary type. But pseudoglandular formation, clear cell change and poor differentiation may make this difficult. In the end I was diagnosed with mucinous adenocarcinoma which is a mucus producing cancer stage 1C. Due to low symptomatology, a lack of screening, and relatively complicated diagnostic procedures of ovarian carcinoma, more and more women are believed to visit their doctors in advanced stage of the disease, complicated with ascitic fluid.
