Cytology

Cytology

There are various approaches to the procurement of a cytol ogy sample. Some samples are easy to obtain, e.g. urine and sputum, whereas others require more intervention. A conven tional cervical smear is obtained by sampling the cervical trans formation zone with a brush/br oom. Bronchial aspirates and washings and bronchial, gastrointestinal and biliary brushings sample a relatively wide area and may therefore be useful for the diagnosis of malignancy . Fine-needle aspiration (FN A) cytology may sample accessi ble sites such as the breast, thyroid and superficial lymph nodes, while ultrasound or CT guidance assists FNA from deeper and less accessible structures, e.g. liver, pancreas , kidney and lung. Ultrasound-guided transbronchial FNA may allow sampling of mediastinal masses and transmucosal FNA may be appro priate for submucosal gastrointestinal lesions or perivisceral lesions. A biopsy taken at the same procedure may accompany laboratory for cytological assessment. Cytology
