Multimodality therapy of endometrial glassy cell carcinoma: a rare type of cancer

Glassy cell carcinoma (GCC) is a rare histologically aggressive cancer subtype of the cervix that is associated with poor prognosis. Only 16 cases of endometrial GCC (EGCC) have been described in the literature to date. The data on prognostic factors and management of EGCC are limited and no optimal treatment protocol has been established. We describe a case of a 67-year-old woman who presented with postmenopausal bleeding and was diagnosed with stage IA EGCC. The patient's risk factors included histology, age and lower uterine segment involvement. The patient was successfully treated with total hysterectomy and bilateral salpingo-oophorectomy with pelvic node dissection followed by adjuvant sandwich chemotherapy and radiotherapy. The patient has no evidence of disease recurrence for 18 months. This is the first case of EGCC management with adjuvant multimodality therapy.

A case of endometrial glassy cell carcinoma: a rare entity which necessitates of better understanding

Endometrial glassy cell carcinoma (EGCC) is a rare neoplasm, accounting for 0.5% of the carcinomas in the endometrium, composed of cells with granular eosinophilic or amphophilic cytoplasm, giving it a ground glass appearance. Till date, only 14 cases of this carcinoma have been reported. In this report, we have described a case of EGCC to help define standard diagnostic criteria and better understand the course, ideal treatment, and accurate prognosis of this disease. We report a case of a 64-year-old woman diagnosed with EGCC after an abnormal pap smear. She underwent a hysteroscopy, which led to the histological diagnosis. Laparotomic total hysterectomy and bilateral salpingo-oophorectomy were performed with pelvic lymphadenectomy and peritoneal and omental biopsies. Final pathological examination confirmed the initial diagnosis. Pelvic nodes removed during surgery and peritoneal and omental biopsies were negative for tumor cells. Treatment was considered appropriate and the patient did not require additional therapies. She was subsequently assigned to clinical follow-up and is alive, with no evidence of the disease.

Cytomorphology of unusual primary tumors in the Pap test

Rare entities in the Pap test, which include neoplastic and non-neoplastic conditions, pose challenges due to the infrequent occurrence of many of these entities in the daily practice of cytology. Furthermore, these conditions give rise to important diagnostic pitfalls to be aware of in the Pap test. For example, cases with adenoma malignum (AM) have been called benign. Recognition of these conditions can help correctly interpret Pap tests as abnormal and thereby ensure that patients get appropriately diagnosed. In this paper, we illustrate and discuss selected uncommon primary neoplastic lesions of the cervix and the vagina that may be seen in Pap test, with a focus on cytomorphology, differential diagnosis and the role of possible ancillary studies. These cases include high-grade squamous intraepithelial lesion cells with small cell morphology; small cell carcinoma; large neuroendocrine carcinoma; glassy cell carcinoma; AM; malignant mixed Müllerian tumor; clear cell carcinoma and primary malignant melanoma. Recognition of these rare variants/neoplasms is important so that involved Pap tests are not diagnosed as benign and that patients with these conditions get additional follow-up.

Glassy cell carcinoma of the endometrium: case report and review of the literature

A szerzők 68 éves FIGO IB stádiumú méhnyálkahártyából kiinduló tejüvegsejtes carcinomás nőbeteg esetét ismertetik, akinél hysterectomia és kétoldali salpingo-oophorectomia, majd sugárkezelés történt. A beteg kétéves utánkövetése alatt daganatmentes volt. Az endometrium tejüvegsejtes carcinomája ritka tumorféleség, eddig 13 esetet közöltek a világon. Mint az adenosquamosus carcinoma rosszul differenciált változata valódi természetének megismerése ma is vita tárgyát képezi. A prognózisának és klinikai jelentőségének tisztázásához újabb közölt esetek és kritikai analízisük szükséges.

Glassy cell carcinoma of the endometrium: A case report and review of the literature

Glassy cell carcinomas are composed of malignant cells showing a "ground glass" cytoplasm, distinct cell membranes, and large nuclei with prominent nucleoli. To our knowledge, only 12 cases of glassy cell endometrial carcinomas (EGCC) have been reported until now. A 63-year-old patient complaining of irregular vaginal bleeding underwent hysteroscopy-guided biopsy revealing a well-differentiated endometrial endometrioid adenocarcinoma. The patient underwent left salpingo-oophorectomy, total abdominal hysterectomy, and pelvic lymphadenectomy. The final diagnosis was FIGO stage IB poorly differentiated endometrial adenosquamous carcinoma with > 90% of glassy tumor cells. The patient is alive, with no evidence of disease for 69 months after diagnosis. We describe an additional case of EGCC and review the data of the literature, emphasizing the need to strictly define the criteria for the diagnosis and the potential usefulness of assessing biologic parameters for the prognostic characterization of this rare entity.

Glassy Cell Carcinoma of the Endometrium

Endometrial glassy cell carcinoma (GCC) is a rare neoplasm, with 11 cases reported in the literature. Although GCC is considered to be a poorly differentiated variant of adenosquamous carcinoma, its real nature is still debatable. We report a case of GCC of the endometrium in a 60-year-old woman and review the literature. The patient presented with vaginal bleeding, and pelvic computed tomographic scan showed a polypoid lesion in the uterine fundus. Histologically, the tumor showed 2 components: a moderately differentiated adenocarcinoma with extensive areas of squamous metaplasia (adenoacanthoma) and a GCC. The clinical stage of the patient's disease was IB as classified by the International Federation of Gynecology and Obstetrics. She was treated by a total abdominal hysterectomy, bilateral salpingo-oophorectomy, and pelvic radiation therapy. The patient was still alive and free of disease at 5 years of follow-up.

Raised serum hCG in a male patient caused by primary jejunal choriocarcinoma

A rare case of primary choriocarcinoma of the jejunum occurred in a 45 year old Chinese man. This tumour was associated with massive melaena and a markedly raised serum human chorionic gonadotrophin (beta-hCG) concentration. Necropsy examination showed no primary lesion in other possible sites including testes, mediastinum, and pineal gland. Histologically, the tumour showed morphology typical of choriocarcinoma with no adenocarcinomatous element identified. The presence of choriocarcinoma in non-gonadal sites may be explained by retrodifferentiation or metaplasia of a conventional carcinomatous component to primitive trophoblasts. Serum beta-hCG level may represent a useful marker in earlier diagnosis and monitoring of this potentially treatable disease.
