Finally, 65 of the 373 patients (17%) underwent brain biopsy, and an additional 14 patients (4%) were found to have lymphomatous involvement of the CNS that had not been detected by either FCA or cytologic examination
One part of the fluid was routinely analyzed by cytologic examination
Precancerous exfoliated cells can be routinely identified in pathology departments by cytologic examination
of washings or brushings from bronchi, oral cavity, esophagus, stomach, bile and pancreatic ducts, sputum and urine; however, the detection of exfoliated cancer cells by routine cytopathological examination is limited because of the presence of few atypical cells in specimens, the difficulty of distinguishing low grade dysplasias from non-specific reactive or inflammatory changes, and the low sensitivity and specificity of the available diagnostic methodology.
Several studies in dogs with pericardial neoplasia have shown that cytologic examination
of pericardial effusion is an unreliable method for distinguishing between neoplastic and nonneoplastic pericardial diseases.
For their part, Andrew Fischer, MD, et al reassess the diagnostic value of conventional cytomorphology in diagnosis and discuss the role of newer technologies, such as endoscopic ultrasound and endoscopic bronchial ultrasound, in quality sampling for cytologic examination
It has been suggested that cytologic examination
of NAF collected from asymptomatic women might be a useful tool for breast-cancer risk assessment.
of the thoracentesis fluid revealed a mixture of numerous mature lymphocytes and blood consistent with a chylothorax with hemorrhage.
After transthoracic aspiration of 100 mL of pleural effusion, cytologic examination
showed an eosinophil count of 5,800/L without parasites.
All volunteers were afebrile during the cytologic examination
Although cytologic examination
of cells in these fluids remains the accepted standard for detection of many cancers, its sensitivity is typically only 50-75% (Table 1).
of the fluid revealed a nucleated cell population of predominantly monocytes, which are found in normal pericardial fluid.
Cervical screening by cytologic examination
of cells is one such example of medical screening where low target prevalence is a characteristic of the visual search task.
