Glassy cell carcinoma of the uterine cervix a rare histology. Report of three cases with a review of the literature.

Glassy cell carcinoma is a poorly differentiated variant of adenosquamous carcinoma of the cervix associated with an aggressive course and a poor prognosis. We present three cases of glassy cell carcinoma of the cervix. Patients presented with a cervical growth which was biopsied. Histology the tumours showed nests of cells with a granular or clear cytoplasm, displaying marked pleomorphism and mitoses. Stroma showed an eosinophilic infiltrate. Two tumours showed a pure glassy cell pattern and one showed glandular differentiation with intracellular and extracellular mucin. Patients were treated with a combination of surgery, radiotherapy and chemotherapy but showed a poor response. Two patients died of the disease of pelvic or distant metastases within two years of diagnosis and one was lost to follow up. Although glassy cell carcinoma runs an aggressive clinical course, an early diagnosis may help in a more effective management and offer a better prognosis.

Diagnostic dilemma in high intracanalar carcinoma of the cervix.

The use of colposcopy for follow up of patients with abnormal cervical smears has considerably increased the rate of detection of cervical malignancies and intraepithelial lesions in recent years. In case the lesion is situated high up in the cervical canal however, the chances of missing out the lesion are considerable. In our case the malignancy was detected only on endocervical sampling, but was missed on scrape as well as on colposcopically directed biopsy. The patient who was in perimenopausal age group, had complaints of post coital bleeding. The initial cervical scrape smear showed only squamous metaplasia. Colposcopically directed biopsy also showed the same findings. On a high index of suspicion clinically, the endocervical sampling was done with a cytobrush, which showed squamous cell carcinoma (SCC) of the cervix. Subsequent hysterectomy of the patient confirmed the diagnosis. Simultaneous endocervical sampling considerably increases the chances of finding an intracanalar lesion, particularly in older women, in whom the transitional zone (TZ) is situated high up in the cervical canal. In such a situation, even a colposcopically directed biopsy may prove inadequate. This was amply proved in our case.
