Gastrointestinal Cytology

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.

Bronchial Tuberculosis

“…Most important is that the brush may retrieve cells from lesions from a large surface area of mucosa. 8 Small, superficial ulcers, plaqueinfiltrated or tumorlike lesions that may not be biopsied may be sampled by the brush. Even when a large number of biopsies are obtained, sampling by the brush is intrinsically more thorough.…”

Ο Ρόλος Της Κυτταρολογίας Υγρής Φάσης Στη Διερεύνηση Των Αλλοιώσεων Του Παχέος Εντέρου

“…Εφαρμόστηκαν διαγνωστικά κριτήρια τα οποία ήδη έχουν περιγραφεί στη βιβλιογραφία. Έτσι αν και υπάρχουν παλαιότερες κυτταρολογικές κατευθύνσεις με κριτήρια διάγνωσης στην κυτταρολογία του παχέος εντέρου όπως παραδείγματος χάριν του Geisinger KR, Silverman JF: Gastrointestinal Cytology αυτές τροποποιήθηκαν προκειμένου τα νέα κριτήρια να είναι πιο εύχρηστα και περισσότερο προσαρμοσμένα στη σύγχρονη πραγματικότητα (89)(90)(91) .…”
