  • epithelial cells
  • Mucinous cystadenocarcinoma of the lung (MCACL) is a very rare malignant mucus-producing neoplasm arising from the uncontrolled growth of transformed epithelial cells originating in lung tissue. (wikipedia.org)
  • Adenocarcinomas can arise in many tissues of the body owing to the ubiquitous nature of glands within the body, and, more fundamentally, to the potency of epithelial cells. (wikipedia.org)
  • There is evidence that some tumors are better explained by the composition theory, due to the aggressive nature of the epithelial cells involved which tend to metastasize much more readily than the sarcomal component. (wikipedia.org)
  • Microscopic
  • The whorled eosinophilic inclusions in LCLC-RP cells give it a microscopic resemblance to malignant cells found in rhabdomyosarcoma (RMS), a rare neoplasm arising from transformed skeletal muscle. (wikipedia.org)
  • Classification
  • Adenocarcinoma - Adenocarcinoma, NOS Classification and external resources Micrograph of an adenocarcinoma showing mucin containing vacuoles. (academic.ru)
  • The 1999 World Health Organization classification system defined MCACL as a cystic adenocarcinoma with copious mucin production that, histologically, resembles (the more common) mucus-producing cystadenocarcinomas originating in the ovary, breast and pancreas. (wikipedia.org)
  • The 2004 revision of the WHO classification noted that the tumors tend to be well circumscribed by a partial fibrous tissue capsule with central cystic change and copious mucin pooling. (wikipedia.org)
  • pancreas
  • b For T3 tumors, the nonperitonealized perimuscular tissue is, for the jejunum and ileum, part of the mesentery and, for the duodenum in areas where serosa is lacking, part of the interface with the pancreas. (cancer.gov)
  • In adults, CEA is primarily expressed in cells of tumors (some malignant, some benign)[citation needed] but they are particularly associated with the adenocarcinomas, such as those arising in the colon, lung, breast, stomach, or pancreas. (wikipedia.org)
  • sarcoma
  • The behavior of MMMT overall is more related to the type and grade of the epithelium than the sarcoma, which suggests the sarcomal portion is an atypical "bystander" than primary driver of the tumor. (wikipedia.org)
  • pancreatic
  • Mark Bloomston, M.D., of Ohio State University, Columbus, Ohio, and colleagues conducted a series of experiments to identify the pattern of miRNA expression in pancreatic adenocarcinoma to attempt to differentiate pancreatic cancer from benign pancreatic tissue and any differences in survival associated with certain miRNA expression. (eurekalert.org)
  • The present report contributes to the growing understanding of the role of miRNAs in oncogenesis and describes the global expression patterns of miRNAs in pancreatic adenocarcinoma. (eurekalert.org)
  • patterns
  • As we and other laboratories continue to identify the expression patterns of various solid tumors, the application of this knowledge may be broad. (eurekalert.org)
  • In addition, newer studies showed that certain gene expression patterns are associated with malignant behaviour of canine mammary tumors. (wikipedia.org)
  • molecular
  • There are several hypotheses on the molecular mechanisms involved in the development of canine mammary tumors but a specific genetic mutation has not been identified. (wikipedia.org)
  • The molecular carcinogenesis of canine mammary tumors are not completely understand. (wikipedia.org)
  • However, the increasing information on molecular pathways involved in the carcinogenesis of this canine tumor has potential to complement and refine the current diagnostic and therapeutic approach to this tumor type. (wikipedia.org)
  • Furthermore, current data show that significant similarities and differences exist between canine and human mammary tumors at the molecular level. (wikipedia.org)
