A Unique Glassy Cell Carcinoma (GCC) of the Cervix Diagnosed during Pregnancy—A Case Report

Glassy Cell carcinoma (GCC) of the cervix is classified as a unique, aggressive neoplasm, with different sensitivity to chemotherapy and radiotherapy. It is such an extremely rare tumor that it is practically not observed during pregnancy. Information on the coexistence of cervical GCC with pregnancy is also unique, so it seems extremely important to disseminate it in order to develop the most effective treatment regimen. Additionally, making any decisions regarding therapeutic methods during pregnancy encounters great ethical problems. We present the case of a 26-year-old pregnant woman, 18 weeks gestation, diagnosed with GCC of the cervix, IB3 grade in the International Federation of Gynecology and Obstetrics (FIGO) scale. Despite the unfavorable prognosis, the use of chemotherapy in a pregnant patient brought on a favorable therapeutic effect, without any negative effects on the fetus. The article also presents a literature review on the epidemiology, pathology, immunohistochemistry, treatment and prognosis of this rare disease.
