Item Isolated jejunal metastasis in a patient with cervical cancer: A case report(2015) Onal, Cem; Nursal, Gul Nihal; Torer, Nurkan; Kayaselcuk, Fazilet; 25949229Background: In approximately 8% of cervical carcinoma patients, gastrointestinal tract is involved, most commonly the rectosigmoid portion, because of local extension. Isolated metastases to small bowel are exceedingly rare. Case report: We present a case of a 63-year-old woman with cervical cancer who developed isolated jejunal metastasis 8 months after postoperative chemoradiotherapy. The patient was alive with no evidence of disease 6 months after resection of metastasis. Very few cases have been reported concerning squamous cell carcinoma of the cervix with documented metastases to the small bowel. There is only one published case report of cervical cancer with multiple metastases to the small intestine and jejunum. To our knowledge, this is the first case of cervical cancer with isolated jejunal metastasis, which was initially demonstrated with positron emission tomography and confirmed histopathologically. Conclusion: Although the exact mechanism underlying the isolated metastasis is unknown, hematogenous spread or tumor seeding during surgery may play a role. (C) 2015 Greater Poland Cancer Centre.

They can display benign and malignant clinical behavior. The most common metastasis sites of malignant stromal tumor are liver, peritoneum, lung and bones. Metastasis to breast is extremely rare. Here, we present a case of GIST with liver, bone, lymph node and breast metastasis by reviewing the literature.Item Comparison of three different risk-stratification models for predicting lymph node involvement in endometrioid endometrial cancer clinically confined to the uterus(2017) Haberal, Ali; Kocaman, Eda; Dursun, Polat; Ayhan, Ali; Korkmaz, Vakkas; Meydanli, Mehmet Mutlu; Yalcin, Ibrahim; Sari, Mustafa Erkan; Sahin, Hanifi; Gungor, Tayfun; 0000-0002-1741-7035; 0000-0002-1486-7209; 0000-0002-7869-9662; 29027396; AAI-9331-2021; AAJ-5802-2021Objective: To compare the clinical validity of the Gynecologic Oncology Group-99 (GOG-99), the Mayo-modified and the European Society for Medical Oncology (ESMO)-modified criteria for predicting lymph node (LN) involvement in women with endometrioid endometrial cancer (EC) clinically confined to the uterus. Methods: A total of 625 consecutive women who underwent comprehensive surgical staging for endometrioid EC clinically confined to the uterus were divided into low- and high-risk groups according to the GOG-99, the Mayo-modified, and the ESMO-modified criteria. Lymphovascular space invasion is the cornerstone of risk stratification according to the ESMO-modified criteria. These 3 risk stratification models were compared in terms of predicting LN positivity. Results: Systematic LN dissection was achieved in all patients included in the study. LN involvement was detected in 70 (11.2%) patients. LN involvement was correctly estimated in 51 of 70 LN-positive patients according to the GOG-99 criteria (positive likelihood ratio [LR+], 3.3; negative likelihood ratio [LR-], 0.4), 64 of 70 LN-positive patients according to the ESMO-modified criteria (LR+, 2.5; LR-, 0.13) and 69 of the 70 LN-positive patients according to the Mayo-modified criteria (LR+, 2.2; LR-, 0.03). The area under curve of the Mayo-modified, the GOG-99 and the ESMO-modified criteria was 0.763, 0.753, and 0.780, respectively. Conclusion: The ESMO-modified classification seems to be the risk-stratification model that most accurately predicts LN involvement in endometrioid EC clinically confined to the uterus. However, the Mayo-modified classification may be an alternative model to achieve a precise balance between the desire to prevent over-treatment and the ability to diagnose LN involvement.Item Cloacogenic Adenocarcinoma of the Vulva: A Case Report and Review of the Literature(2018) Tepeoglu, Merih; Uner, Halit; Haberal, Asuman Nihan; Ozen, Ozlem; Kuscu, Esra; 28272666Primary adenocarcinoma of the vulva, unrelated to the native glands of perineum is an extremely rare neoplasm. Despite awareness of this lesion for over 40 years, the origin is not beyond speculation. The most reasonable hypothesis is based on the remnants of cloacal differentiation during early days of life. Here we report the case of a 60-year-old patient with a vulvar mass, who underwent partial vulvectomy and bilateral regional lymph node dissection. The tumor was composed of papillary and complex glandular structures and exhibited diffuse positivity for cytokeratin 20 and polyclonal CEA, CDX2, and focal positivity with cytokeratin 7. Unlike the indolent behavior of this malignant neoplasm according to the literature, we found two metastatic inguinal lymph nodes. She did not receive adjuvant therapy and is still alive, free of disease 38 months after surgery. We present different aspects of vulvar adenocarcinomas with a case report.
