Combined signet ring cell and glassy cell carcinoma of the uterine cervix arising in a young Japanese woman: a case report with immunohistochemical and histochemical analyses.
ABSTRACT Signet ring cell carcinoma and glassy cell carcinoma are both rare histological subtypes of uterine cervical cancer. This report is of a case of uterine cervical carcinoma arising in a 29-year-old woman who had major components of signet ring cell carcinoma and glassy cell carcinoma within the same tumor. Histochemical and immunohistochemical analyses, including high and low molecular weight cytokeratins, p63 and MUC5AC, additionally demonstrated the squamous and adenocarcinomatous differentiation in the neoplastic cells, which showed otherwise unclassifiable morphology on the haematoxylin-eosin sections. A wide range of differentiation described above supports the speculation that glassy cell carcinoma may arise from the multipotential immature cells that can differentiate into both squamous and glandular cells. It would be precise to classify this tumor as adenosquamous carcinoma. Although adenosquamous carcinoma is not a rare histological subtype in the uterine cervix, it should be necessary to report the presence of glassy cells and signet ring cells when present because the presence of both components is associated with an unfavorable clinical behavior.

ABSTRACT: Resumen La mayoría de las neoplasias malignas gástricas corres- ponden histológicamente a adenocarcinomas de tipo difuso o intestinal, siendo otras variedades mucho me- nos frecuentes. Reportamos un caso de tumor epitelial maligno, cuyas características histológicas y citológicas corresponden a una entidad inusual aunque bien defi- nida que puede aparecer en el cérvix y menos frecuen- temente en el endometrio, conocido como adenocarci- noma de la variante glassy - cell. No hemos encontra- do ningún reporte previo de este particular tipo de tu- mor en localización gástrica. Se discuten la histogéne- sis y los diagnósticos diferenciales. Summary "Glassy - Cell" like adenocarcinoma: A new variant of gastric tumor Most gastric malignancies correspond histologically to adenocarcinomas, either of the intestinal or diffuse ty- pe, other tumoral varieties being much less frequent. We report a case of a malignant epithelial tumor, who- se histological and cytological characteristics correspond to an unusual, although well defined entity, which may appear in the cervix and less frequently in the en- dometrium, known as adenocarcinoma of the glassy - cell variety. We have not found any previous reports of this particular .

ABSTRACT: To summarize the data on the incidence, clinical behavior and overall survival of patients with Glassy Cell Cervical Carcinoma (GCCC). Twenty-four case series and fifteen case reports identified by searching PubMed database qualified for inclusion in this study. The published cases were combined with data from a retrospective chart review of patients with GCCC in two major teaching hospitals in Brooklyn, NY. A total of 292 cases were collected through our literature and chart review. Median age at diagnosis was 45years old (range 12-87years of age). GCCC incidence ranges from 0.2-9.3% of all cervical cancers and 2-30.2% of cervical adenocarcinomas. The stage distribution is similar to squamous cell carcinoma with 79% of the patients being diagnosed with Stage I or II disease. Most common sites of recurrence for Stage I patients are the vagina and pelvis. In Stage II patients locoregional and distant metastases are equally common. Recurrence rate was higher among patients treated only with surgery (32.7%), as compared to patients treated with surgery followed by radiation (11%) or patients treated with radiation only (10%). Median overall survival (OS) was 25months (95% CI 8.4-41.6). Overall 5-year survival for all stages is lower when compared to all cervical cancers (54.8% vs 75%). There was no interaction between race and OS (p=0.66). GCCC is a rare histologic type of cervical cancer that presents at a younger age, is associated with high risk for distant failure and carries worse prognosis as compared to the squamous cell type. Radiation therapy is associated with decreased risk of recurrence.Gynecologic Oncology 02/2014; · 3.69 Impact Factor

ABSTRACT: Objective To present the case report of a patient with undifferentiated and diffuse signet-ring cell gastric carcinoma in which FDG-PET evidenced recurrent disease.Materials and methodsThe patient was diagnosed of a stage III gastric carcinoma in 1994 and was treated with a subtotal gastrectomy. In February 2003, recurrent disease was detected in mediastinal and left supraclavicular lymph nodes. The patient was treated with chemotherapy and radiotherapy, reaching a complete response. After 6 months free of disease, he presented an elevation of the tumor markers with negative results in conventional imaging methods (upper digestive endoscopy, bone scintigraphy, and CT). An FDG-PET scan was performed to rule out recurrent disease.ResultsFDG-PET detected pathologic findings suggestive of malignant disease in right supraclavicular and mediastinal lymph nodes. These findings were confirmed by clinical follow-up and with another CT scan performed 4 months later.Conclusions In this case report we stress the importance of early recurrence by FDG-PET in a non-intestinal gastric carcinoma. This is of interest given the greater difficulty to detect mucous secreting and/or producing carcinomas with the PET-FDG.Revista Española de Medicina Nuclear 10/2005; 24(5):326–330. · 0.89 Impact Factor
