Methods: One hundred and forty one consecutive patients who underwent radiologically guided combined FNA/NCB of abdominal lesions over a four year period were reviewed. Sensitivities were compared using McNemar’s test. The key difference between histopathology and cytology is that histopathology is the study of diseased tissues using a microscope while cytology is the study of individual cells of the body..

For clinicians who are competent at examining aspirated samples of basic lesions (e.g., lipoma, mast cell tumor, septic inflammation), cytology may be provided as a point-of-care test. Biopsy, however, has the advantage of providing the pathologist with much more detailed diagnostic information by virtue of the tissue architecture and associated tissue responses contained within tissue specimens. Results. We have not attempted to relate studies of sputum, obtained either before or after bronchoscopic examination, to the bronchoscopic results, but obviously these patients did not have “positve” findings on examinations of sputum before bronchoscopic examination. Brush cytology vs. endoscopic biopsy for the surveillance of Barrett's esophagus. Histology provides excellent details of tissue architecture while cytology provides excellent cellular details. • Core biopsy,unlike FNA cytology,yields tissue fragments allowing architectural features of the lesion to be identified to determine whether ductal carcinoma in situ (DCIS) or invasive carcinoma is present.
