1. Phenotype characterization of the mucinous ovarian tumors / Caracterizaçao fenotípica dos tumores mucinosos do ovário
NTRODUÇÃO: Neoplasias mucinosas primárias do ovário apresentam muitos pontos de controvérsias em relação ao seu padrão de diferenciação, sendo classificadas como tumores benignos, borderline e malignos.Elas também são classificadas em diferentes fenótipos, recentemente designadas como gastrointestinal e seromucinoso. Sua heterogeneidade tem prod

2. Mucinous cystadenoma and cystadenocarcinoma of the vermiform appendix with particular reference to mucocele and pseudomyxoma peritonei
Ten cases of mucocele of the vermiform appendix are described. Eight cases were of mucinous cystadenoma of the appendix and six cases showed acute inflammation. Two of the six cases showed pseudoinvasion of the appendix and in a further case the appendix had perforated with extrusion of a misplaced neoplasm. Two cases were of mucinous cystadenocarcinoma and

3. Cyst fluid analysis in the differential diagnosis of pancreatic cysts. A comparison of pseudocysts, serous cystadenomas, mucinous cystic neoplasms, and mucinous cystadenocarcinoma.
Pancreatic cystic lesions include inflammatory pseudocysts, benign serous tumors, and mucinous neoplasms, some of which are malignant. Clinical and radiologic indices are often inadequate to discriminate reliably among these possibilities. In an attempt to develop new preoperative diagnostic criteria to assist in decisions regarding therapy, the authors have

4. Mucin-producing neoplasms of the pancreas. Intraductal papillary and mucinous cystic neoplasms.
OBJECTIVE: The authors compared the clinicopathologic features of the intraductal papillary and mucinous cystic neoplasms of the pancreas and clarified the similarities as well as the differences between these two tumors. In addition, they reviewed 104 cases of the intraductal papillary neoplasm in the English literature to provide a global view of the condi

5. In vivo horizontal oncogenesis by a human tumor in nude mice.
A human mucinous cystadenocarcinoma of the ovary was propagated in nude mice. After cryopreservation of the 3rd-passage xenograft for 4 years, subsequent in vivo transplants showed the emergence of two distinct populations, one resembling the original human adenocarcinoma and the other resembling a spindle-cell sarcoma. These two tumor cell populations were

6. Carcinosarcoma arising in a dermoid cyst of the ovary.
A case of carcinosarcoma arising within an otherwise benign cystic teratoma is reported. The patient, a 78 year old nulliparous woman, presented with right sided abdominal pain of short duration and subsequently underwent a bilateral salphingo-oophorectomy. Slicing of the left ovary revealed a unilocular cyst containing hair admixed with soft yellow material

7. Giant Syncytia and Virus-Like Particles in Ovarian Carcinoma Cells Isolated from Ascites Fluid
Ovarian cancer cells were isolated from ascites fluid of 30 different patients diagnosed with cystadenocarcinoma of ovaries. Large colonies of malignant ASC cells were observed during the first week of cell growth in vitro. Colony formation was followed by fusion of cells and formation of large multinucleated and highly vacuolated syncytia. In contrast, cell
