• Although pancreatic cysts are heterogeneous, they can be clustered into the larger groups of pseudocysts (PC), and serous and mucinous pancreatic cystic neoplasms (S-PCN and M-PCN, respectively). (bvsalud.org)
  • T his is a state-of-the-art review of the molecular genetics of pancreatic neoplasms. (coek.info)
  • Although understanding of the molecular features underlying pancreatic neoplasms is still in its infancy, a strong emphasis on the relevance of these findings for the practicing surgical pathologist is provided. (coek.info)
  • INTRODUCTION Pancreatic cancer is the fourth leading cause of cancer death in both men and women in the United States.1 There have been significant advances in our understanding of the genetics of pancreatic neoplasms in the past 2 decades, as well as an explosion of information over the past 3 years, largely because of the availability of whole genome and exome sequencing technologies.

  • This article provides a state-of-the-art review of the molecular genetics of pancreatic neoplasms with a strong emphasis on the relevance of these findings for the practicing surgical pathologist. (coek.info)
  • It ranges from a well-differentiated tumor with EPITHELIAL CELLS indistinguishable from normal HEPATOCYTES to a poorly differentiated neoplasm. (lookformedical.com)
  • A small proportion of these tumors show large ducts lined by neoplastic cells, the so-called large-duct variant of adenocarcinoma. (coek.info)
  • Rectal cancer is a common malignancy of the gastrointestinal tract. (bvsalud.org)
  • Immunohistochemical stain for CK7 highlighted the epithelial lining of the cystic spaces with weak, patchy labeling for inhibin (Figures 3 and 4). (pbpath.org)
  • The epithelial neoplasms have occurred in older dogs compared to those of other histogenic origins (mesenchymal and other origins/round cells). (bvsalud.org)
  • The frequency was 48% of epithelial neoplasms, 32% of mesenchymal neoplasms, and 10% of neoplasms with other origins and round cells. (bvsalud.org)
  • This study aimed to quantify nasosinusal neoplasms diagnosed in dogs in 20 years (2000-2019) and characterize the main clinical, macroscopic, and histological aspects of these neoplasms. (bvsalud.org)
  • The main clinical signs were similar between the histogenetic categories, related to the involvement of the upper respiratory tract, sometimes accompanied by nervous signs (when there was brain invasion of nasal neoplasms or vice versa). (bvsalud.org)
  • Through this study, it was possible to establish the frequency of these neoplasms in 20 years and their clinical, macroscopic, and histological characteristics. (bvsalud.org)
  • Figure 1: Multiloculated cyst with intervening hyalinized fibrous stroma, cystic spaces are lined by cuboidal to flattened cells with clear cytoplasm, without nuclear atypia. (pbpath.org)
  • Examination on higher magnification demonstrated focal areas of small glandular/cystic spaces lined by single layer of bland, cuboidal to flattened cells with uniform nuclei and clear cytoplasm similar to those present the resection specimen (Figure 7). (pbpath.org)
  • EUS and CT scan showed a multilobulated cystic lesion (2.5 cm) with a solid component, not in communication with the main pancreatic duct. (pbpath.org)
