A four-year prospective study of endoscopic cytology and histology was carried out on 64 patients suspected of having a malignant lesion at the junction of the lower oesophagus and cardia. The final diagnosis was malignant in 18 and benign in 46 cases. Biopsy touch smear cytology was the most accurate technique with a sensitivity of 100% compared with 820% for brush cytology and 89% for biopsy ...

An adenoid cystic carcinoma (ACC) of the lung is a malignant tumor that arises in ducts of bronchial submucosal mucous glands. ACC of the lower respiratory tract constitutes ≤0.2% of all primary pulmonary tumors. A diagnosis of ACC on cytology is uncommon even on exfoliative cytology, as well as fine needle aspiration cytology. To the best of our knowledge, this is the second case of bronchial ...

Urine cytology often is used to identify BK virus in kidney transplant recipients in the cytology laboratory. To assess the usefulness of the shell vial cell culture assay to identify BK virus, urine samples from 42 kidney transplant recipients were tested by the urine cytology and shell vial cell culture assays. The shell vial cell culture assay is just as sensitive and specific as urine cytol...

I this issue, Arbyn et al (see p. 167) update the evidence about the accuracy of liquid-based cytology compared with conventional cytology, and the results are not encouraging.1 In summary, best evidence suggests that liquid-based cytology does not lead to more disease detection and appears to increase false-positive testing, sobering news given that over 80% of U.S. obstetrician–gynecologists ...

OBJECTIVES Traditionally, urine cytology has been considered as the gold standard for bladder cancer screening. However, new methods are playing new roles in these cases. In order to assess the value of cytology of voided urine we performed one comparative study between cytology and biopsy. METHODS We retrospectively analyzed the results of urine cytology and biopsy follow-up in 109 patients....

Diagnostic cytology is a relatively new science. Cytology (Greek word: kytos = hollow vessel) is the study of individual cells and their intrinsic characteristics and functions. George Papanicolaou is considered the father of exfoliative cytology, but cytology was first used in cutaneous disorders by Tzanck in 1947, for the diagnosis of vesiculo-bullous disorders, particularly herpes simplex. S...

The surgical histology report was the standard for confirming the accuracy of the diagnostic FNA cytology classification. The specificity of the FNA cytology was estimated using two approaches. One was to consider the FNA as a diagnostic test if the FNA specimens were interpreted as suspicious of malignancy or positive for malignancy, and the remaining categories were classified as negative. Th...
