Orlandi R, Vallesi E, Calabrò S, Vastolo A, Musco N, Troisi A, Polisca A, Lombardi P, Cutrignelli MI.  |  Although all sites are amenable to cytological sampling, the lower tract is usually the target for the detection of infections, benign lesions, and neoplastic processes. The value of exfoliative cytology in oral cancer screening programmes as a public health measure is discussed. Indications a. The highest diagnostic yield for bronchial brushing and bronchial wash is for squamous cell carcinoma, adenocarcinoma, and small cell carcinoma (in that order). Exfoliative cytology, taking brush biopsies, is advocated for evaluation of macroscopically suspicious lesions of the oral mucosa that are detected clinically by screening. The principal indications for exfoliative cytology of the respiratory tract are as follows: 1. Generally, lung metastases are identified in 30–55 % of all cancer patients. The examination isnotuncomfortable for the patient and can be repeated many times. • Intraoral exfoliative cytology, originally developed by Silverman and Sandler, although eliminates many of the disadvantages of the biopsy, by no means supplants the usual biopsy study. If indicated, microbiological cultures can also be performed concurrently. Would you like email updates of new search results? Oral exfoliative cytology can be a powerful tool for early detection of malignant and premalignant lesions as well as for some viral and fungal infections, if the limitations of the method are thoroughly understood and appreciated by the dental clinician. In this chapter only the lower respiratory tract will be addressed. In anoestrus, predominantly parabasal cells with a large nucleus and homogenous cytoplasm are found. The overall sensitivity increases with a combined use of different sampling modalities. Residual material can be rinsed in collection medium and used to process additional LBP for special stains, immunostains, or cell block preparation, especially if tissue fragments are noted. The indications for oral exfoliative cytology are reviewed and a technique for cell collection and smear examination is presented. conventional exfoliative cytology sample collection 3. Less than half of the dentists (41.7%) had been taught how to obtain a cytologic smear, and only 26.0% knew the clinical indications for doing so. As this phase progresses, the percentage of large intermediate cells and nucleated superficial cells increases. Tracking changes in the morphology of desquamated vaginal epithelial cells provides a convenient means of assaying changes in estrogen levels. The concordance rate of bronchial brushing and TBBx is ~97 %. Vaginal cytology has many practical applications in the evaluation of both the normal and abnormal bitch. According to the American Cancer Society, there will be approximately 225,000 new cases of lung cancer and about 158,080 deaths from the disease (accounting for one of four cancer deaths) in 2016.

The principal indications for exfoliative cytology of the respiratory tract are as follows: Workup of a solitary pulmonary nodule detected on diagnostic or screening CT, Workup of a pulmonary nodule detected on CT in patients with a prior malignancy, Workup of pulmonary infiltrates to exclude infectious etiology. At the time of diagnosis, 25 % of patients have regional metastasis, and 55 % of patients have distant spread of disease. Diagnostic sensitivity of sputum cytology is directly proportional to the number of samples examined, and its accuracy approaches 95 % when five (5) sequential samples are examined. The cells may be obtained by such procedures as aspiration, washing, smear, and scraping, and the technique may also be applied to secretions such as sputum, urine, abdominal fluid, prostatic secretions, and … The value of exfoliative cytology in oral cancer screening programmes as a public health measure is discussed. • The Oral Biopsy – Avoidable Pitfalls.
