Abstract
The commonest site of malignancy in the female genital tract is the cervix. Dysplasia and carcinoma in situ are the final stages of development through which the cervical carcinoma may pass. These two major histological intities are termed cervical intra- epithelia neoplasia (CIN) (Richard 1967, koss 1978). The cervical intra - epithelial neoplasia (CIN) are subdivided into C.I.N. I equivalent to mild dysplasia. C.I.N. II to moderate dysplasia and C.I.N. III to severe dysplasia and carcinoma in situ (C. I .S.) . The lesions of (C.l.N.) are pre-clinical that they can not be recognised by traditional methods of clinical examination. The most important two diagnostic tools available for the clinician for the diagnosis of these lesions, are cervical exfoliative cytology and colposcopy. The increasing accuracy achieved by exfolicative cytology over the past two decades in predicting epithelial neoplastic changes in the uterine cervix had been well recognised. Since the pioneer work of papanicolaou and Traut 1943. The cervical smear became a window through which the change of epithelium from normal to abnormal could be revealed. This change has its inception long before gross lesion becomes present.
