Abstract Carcinomas of the cervix may be categorized on morphological grounds into four main groups: squamous carcinomas; adenocarcinomas; neuro-endocrine tumours; and others including adenosquamous carcinomas. Each group contains several morphological subvariants. Invasive squamous carcinomas and adenocarcinomas are preceded by cervical intra-epithelial neoplasia and cervical glandular intra-epithelial neoplasia, respectively. Each is graded into low and high grade. Micro-invasive carcinomas with stromal invasion less than 3mm in depth have a minimal chance of lymph node metastasis. When there is lymph node involvement, the obturator node may be the most common. Presence or absence of lymph node involvement, tumour size and depth of invasion are the important independent histopathological indicators of prognosis. The presence or absence of vascular space invasion is a valuable prognostic indicator. Small cell carcinomas, large cell neuro-endocrine carcinomas and possibly adenoid cystic carcinomas are aggressive. With these exceptions, it is doubtful whether tumour type is of much clinical significance. Tumour grade, as currently assessed, is of no significant value.
