  • Chest X-ray revealed (15 mg/kg) was initiated for pulmonary adenocarcinoma a tumor in the left hilar region and left pleural effusion. (deepdyve.com)
  • While FA can be diagnosed via biopsy, bronchial brushings, and immunocytochemistry, examination of the whole tumor is required to rule out biphasic pulmonary blastoma, a mixed tumor of higher aggressiveness, wherein FA occurs admixed with primitive blastoma cells. (wikipedia.org)
  • Similar to other adenocarcinoma, if this tumor is well differentiated (low grade) it will resemble the normal glandular structure. (wikipedia.org)
  • Foci of squamous metaplasia and dysplasia may be present in the epithelium proximal to adenocarcinomas, but these are not the precursor lesions for this tumor. (wikipedia.org)
  • It can sometimes occur within a pulmonary bronchocele, and this tumor entity should be kept in mind after identification of a bronchocele with suspicious or non-prototypical imaging characteristics. (wikipedia.org)
  • mucinous adenocarcinomas
  • The majority of mucinous adenocarcinomas expressed thyroid transcription factor 1, Napsin A, Villin and Cam5.2 proteins. (spandidos-publications.com)
  • Microscopic characteristics of rhabdoid cells include: Oval to polygonal cell shape Eosinophilic, hyaline-like perinuclear agglomerations of intermediate filaments Compressed, eccentric nuclei Prominent central macronucleoli (one or two) Abundant eosinophilic cytoplasm Reticular chromatin pattern The differential diagnosis of LCLC-RP includes secondary metastatic lesions, melignant melanoma of the lung with rhabdoid phenotype, mucinous adenocarcinomas (particularly those featuring signet-ring cells), rhabdomyosarcoma, epitheloid angiosarcoma, pleural mesothelioma, and plasmacytoma.

  • pleural
  • Case presentation: A 76-year-old man was diagnosed with pulmonary adenocarcinoma with pleural dissemination and liver and adrenal metastases. (deepdyve.com)
  • The purpose of this study was to test napsin A as a diagnostic marker of metastatic lung adenocarcinoma in pleural effusions, and to compare its performance with TTF-1. (lu.se)
  • Napsin A and TTF-1 reactivities were determined immunohistochemically on.formalin-fixed paraffin embedded cell blocks from 50 pleural effusion (5 mesotheliomas, 10 mesothelial proliferations, 12 pulmonary, and 23 nonpulmonary metastases). (lu.se)
  • EML4-ALK
  • Methods A series of consecutive 111 lung adenocarcinomas, including 10 cases harboring EML4-ALK fusion, were analyzed using Affymetrix GeneChip and our robust algorithm, CNAG/AsCNAR, to perform sensitive analysis of copy number alteration and allelic composition. (aacrjournals.org)
  • mucin
  • Poorly differentiated adenocarcinoma will not resemble the normal glands (high grade) and will be detected by seeing that they stain positive for mucin (which the glands produce). (wikipedia.org)
  • 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)
  • cancer
  • Two hundred seventy-five patients with pulmonary AD of South China admitted into Zhejiang Cancer Hospital from July 2007 to October 2011 were randomly selected, and their clinicopathological data were collected at the same time. (springer.com)
  • In the respiratory tract, microbiota is associated with many lung diseases, including chronic obstructive pulmonary disease (COPD) ( 12 , 13 ), asthma ( 14 ) and lung cancer ( 15 ). (spandidos-publications.com)
  • Adenocarcinoma is the most common form of lung cancer with poor-prognosis due to late-stage detection and resistance to conventional treatment. (aacrjournals.org)

  • Of the types of non-small cell lung cancer histologies, adenocarcinoma is the type that most often harbors these mutations. (wikipedia.org)
  • however, among people who have smoked fewer than 100 cigarettes in their lifetimes ("never-smokers"), adenocarcinoma is the most common form of lung cancer. (wikipedia.org)
  • smokers
  • IPASS studied 1,217 patients with confirmed adenocarcinoma histology who were former or never smokers. (wikipedia.org)
  • According to the Nurses' Health Study, the risk of adenocarcinoma of the lung increases substantially after a long duration of previous tobacco smoking, with a previous smoking duration of 30 to 40 years giving a relative risk of approximately 2.4 compared to never-smokers, and a duration of more than 40 years giving a relative risk of approximately 5.
