  • Title: Gastrointestinal cytology.
    Author: Geisinger KR, Wang HH, Ducatman BS, Teot LA.
    Journal: Clin Lab Med; 1991 Jun; 11(2):403-41. PubMed ID: 1873965.
    Abstract:
    Since the development of the fiberoptic endoscope, laboratories have received cytologic specimens obtained from all segments of the gastrointestinal tract in increasing numbers to identify infectious agents and neoplasms. Adenocarcinomas generally are easily diagnosed and distinguished from reparative atypia, but their precursor lesions, dysplasia and adenomas, provide greater interpretive challenges. The same is true for such entities as malignant lymphomas. Most mesenchymal tumors remain outside the diagnostic capabilities of most cytologists.
