Adenosquamous carcinoma of uterine cervix is a preponderantly high grade neoplasm configured of admixed glandular articulations and squamous epithelium wherein glassy cell carcinoma emerges as an exceptional, aggressive variant. Adenosquamous carcinoma is posited to arise from sub-columnar reserve cells confined to endocervical basal epithelium. Cytological smears depict papillary articulations admixed with bland columnar epithelial cells and high grade squamous intraepithelial lesion. The biphasic tumour is composed of well defined, malignant components of glandular articulations and poorly differentiated squamous epithelium. Glassy cell carcinoma demonstrates solid cell nests comprised of pleomorphic, polygonal tumour cells pervaded with glassy, eosinophilic cytoplasm, enlarged, eosinophilic nuclei, prominent nucleoli and distinct cytoplasmic membrane. Neoplastic cells appear enmeshed within an intense inflammatory cell infiltrate with significant eosinophils. Glassy cell carcinoma appears immune reactive to MUC1, MUC2, epithelial membrane antigen (EMA), CAM5.2 or p63 with focal immune reactivity to carcinoembryonic antigen (CEA). Adenosquamous carcinoma requires segregation from neoplasms such as adenocarcinoma with coexisting squamous intraepithelial lesion (SIL), adenoid basal carcinoma, cervical extension of endometrial adenocarcinoma, and squamous cell carcinoma with focal mucin droplets, large cell non keratinizing squamous cell carcinoma or lymphoepithelioma-like carcinoma. Tumefaction may be appropriately treated by radical abdominal hysterectomy followed by adjuvant chemotherapy and radiation therapy.
