Cytological studies began with the English scientist Robert Hooke’s microscopic investigations. A cytology report recorded as suspicious is not considered as diagnostic of cancer and unless supported by a positive biopsy (as reported on a pathology report) or by a clinical impression of cancer, these cases should not be abstracted.. In the present study we had compared cytological findings with follow-up histology sections.

Cytology and Histology. Recommended Reading. The medical specialty that provides microscopy and other laboratory services (e.g., cytology, histology) to clinicians. For example, cytology on a neck node that confirms metastatic squamous cell carcinoma from an oropharyngeal primary would be sufficient to direct ongoing management, whereas in lymphoma, a larger biopsy or the entire node may be required to evaluate nodal architecture in order to decide optimal first-line management. Histology is the final analysis of the microscopic anatomy of cells and tissues whereas the cytology is the straightforward analysis of cells solely. The specialist doctor who does the examination under the microscope is called a pathologist. Subject enrollment was carried out using an online central enrollment system. easily by fine needle cytology. The primary objective of pathological techniques is the diagnostic classification of pathologically altered tissue and the assessment of cell morphology ().In addition to post-mortem examination, histological and cytological evaluation of tissue is the main task in pathology.
