Clear cell adenocarcinoma of uterine cervix is predominantly comprised of clear cells or hobnail cells articulating distinct architectural patterns as solid, tubulocystic or papillary. Tumour cell cytoplasm is clear, eosinophilic with intracytoplasmic hyaline globules and enhanced nuclear grade. A historic association with intrauterine diethylstilbestrol (DES) exposure is enunciated. Sporadic overexpression of p53 tumour suppressor gene may be observed. Neoplasm manifests with vaginal bleeding, postcoital bleeding or abnormal vaginal discharge. Cytological smears exhibit sheets, clusters or papillae of tumour cells permeated with delicate, vacuolated, glycogen rich or finely granular cytoplasm, enlarged, pale, spherical nuclei with prominent nucleoli or naked nuclei with tigroid background composed of granular, reticulated substance. Clear cell adenocarcinoma appears immune reactive to pan-cytokeratin as AE1 / AE3, CAM5.2, CK7, CK8, CK18, CK19, HNF1β, Napsin A, Ki67 or epithelial membrane antigen (EMA). Tumefaction requires segregation from neoplasms such as microglandular hyperplasia, Arias-Stella reaction, primary alveolar soft part sarcoma, mesonephric adenocarcinoma, metastatic clear cell renal cell carcinoma, endometrioid carcinoma, serous carcinoma, squamous cell carcinoma, urothelial carcinoma, adenosis, endometrioid adenocarcinoma with clear cell or secretory change, gastric subtype of endocervical adenocarcinoma or yolk sac tumours of uterine cervix. Neoplasm may be preliminarily subjected to radical hysterectomy with pelvic lymphadenectomy or fertility sparing radical trachelectomy
