Glassy cell carcinoma is a rare clinical entity involving uterine cervix with aggressive course and relatively poor prognosis. It is a poorly differentiated variant of adenosquamous carcinoma. This neoplasm has poor response to radiotherapy and carries worse prognosis than the usual types of adenocarcinoma and squamous cell carcinoma. A case of a 40-year-old female patient is reported and the published literature is reviewed.

| Introduction|| |
Glassy cell carcinoma (GCC) of the cervix is considered a rare tumor involving the cervix and accounts for around 1% of all cervical cancers. It was originally described in the cervix by Glucksmann and Cherry in 1956. It is a poorly differentiated subtype of adenosquamous carcinoma. It is characterized by glassy cells which have abundant glycogen in their cytoplasm. It typically affects young women, with peak incidence between third and fourth decades of life. GCC runs an aggressive course; the disease is already at an advanced stage at the time of diagnosis. Despite a combination of radical surgery, chemotherapy, and radiotherapy, the prognosis is reserved.
| Case Report|| |
A 40-year-old menopausal, multiparous female patient presented with a history of bleeding and discharge per vaginum for 1 month. She was a smoker for the past 25 years and menopausal for the last 3 years. At assessment, local examination and ultrasound examination were performed. Per speculum examination revealed a 4 cm × 4 cm fungating growth involving both the cervical lips. Upper rim of the vagina and parametrium were also involved. Ultrasonography showed a heterogeneous hypoechoic mass of size 6.2 cm × 6 cm × 5.8 cm in the cervix extending into lower uterine segment. The mass was encasing bilateral ureters causing bilateral hydronephrosis, hydroureter, and pyometra.
A biopsy was taken from the mass which revealed tissue fragment comprised nests and sheets of tumor cells surrounded by dense stromal inflammatory infiltrate, comprised lymphocytes, plasma cells, and eosinophils [Figure 1].

The tumor cells were pleomorphic with vesicular nuclei, focally prominent nucleoli, and moderate amount of eosinophilic cytoplasm with well-defined cell boundaries [Figure 2]. Numerous mitotic figures and occasional bizarre tumor cells along with focal keratin pearl formation were seen [Figure 3]. On the basis of the histopathological examination, the diagnosis of GCC of the uterine cervix was made. The patient then received four cycles of radiotherapy till date and is on follow-up. Due to deranged liver function tests, no chemotherapy was given to the patient.

| Discussion|| |
The World Health Organization classifies GCC as a subtype of epithelial tumors, occurring in 1%–5% of all cervical cancers. The mean age is 10 years younger than in other histological subtypes. A strong association has been found with high-risk human papillomavirus (HPV). An association has also been found with recent and current pregnancy.,,
The tumor usually presents as an ulcerated or nonulcerated growth around the squamocolumnar junction. It may grow into the endocervical canal in a barrel-shaped fashion with extension into the vagina and parametrium. It can also present as a cervical polyp or as a microinvasive lesion. Despite a large tumor volume, the cervical stroma is generally involved only superficially.
On histomorphology, the tumor can be missed for large cell nonkeratinizing squamous cell carcinoma, lymphoepithelioma-like carcinoma, and clear cell carcinoma (mesonephroid carcinoma) of the cervix. Abundant glycogen in the cell cytoplasm gives them their characteristic glassy appearance (cytoplasm resembles ground glass, hence the name “glassy cell”). The exact percentage required for diagnosing this lesion is not exactly known; however, anywhere from 30% to 100% of the cells with this “glassy” appearance in a tumor makes it GCC. Based on the criteria established by Gluksmann and Cherry and amplified by Littman et al., there are three main criteria for microscopic diagnosis of GCC: (1) cells with moderate amount of cytoplasm and a ground glass or finely granular appearance; (2) a distinct cell cytoplasm that stains with eosin and periodic acid-Schiff; and (3) large nuclei with prominent nucleoli.
It is important to differentiate it from adeno or squamous cell carcinoma as GCC has a rapid progression rate and a high rate of metastasis outside the pelvis. Local recurrence occurs to apex of vagina, parametrium, and para-aortic lymph nodes. Distant metastasis to lung, liver, spleen, and bones have been observed. Some studies have shown myocardial metastasis on necropsy, thus suggesting both hematogenous and lymphatic spread of metastasis. Jung et al. in their study revealed that GCC has association that high-risk HPV types 18, 16, and 31. Immunohistochemically, GCC expressed markers for both squamous cell carcinoma (p63 and CK34βE12) and adenocarcinoma (CAM5.2, MUC1, MUC2, and CEA). Ki-67 proliferation index was high (≥70%). Owing to its aggressive nature and depending upon the stage of the disease, surgery, chemotherapy, and chemoradiotherapy form the treatment modalities.,
| Conclusion|| |
GCC is a poorly differentiated adenosquamous carcinoma of the cervix, hallmarked by aggressive behavior, occurrence in association with pregnancy, and a poor patient survival rate. It typically occurs in young women. They grow rapidly and may present at an advanced stage. Due to its aggressive course, early diagnosis and treatment are required, but the prognosis still remains dismal.
