Item Gastric Polyps: A Retrospective Analysis of Endoscopic Biopsies: A Single Center Study in Central Anatolia(2019) Erinanc, Hilal; Unler, Gulhan Kanat; Gokturk, Huseyin Savas; Ozgur, Gulsum TekeObjective: Gastric polyps accounts for %6 of gastrointestinal endoscopy. Geographical differences occur in the prevalence of them. We aimed to determine the spectrum of gastric polyps. Matherial and method: Data including demographics, medical history and histological characteristics of polyps and Helicobacter pylori were obtained retrospectively. Results: Of the 24568 endoscopies performed, 184 patients were identified as having gastric polyps. The most frequently encountered were hyperplastic polyps (62%), followed by fundic gland polyps (19,3%) and adenomatous polyps (3, 8%). The corpus (36,4 %) was the most common site and the antrum (25%) was the second. Female patients were more affected than male patients (64,7%). Majority of the polyps (88%) were smaller than 1 cm in diameter. The mean age was 62,10+13,4 (range:30-90) years. Fundic gland polyps were observed at younger age (mean age: 56,58) compared to other gastric polyps. Intestinal metaplasia was more frequently encountered in hyperplastic polyps than in fundic gland polyps. Conclusion: In this study, hyperplastic polyps are the most common in our population however there was no association between the hyperplastic polyps and H. pylori infection. H. pylori infection ratio was similar in both hyperplastic polyps and fundic gland polyps however all of the patient have chronic gastritis. This findings suggest chronic gastritis also play role in hyperplastic polyps development. The study also showed that H. Pylori infection is still common in our country and further studies need to find efficacy of H.pylori treatment.Item Predictive values of vascular endothelial growth factor and microvessel-density levels in initial biopsy for prostate cancer(2016) Kervancioglu, Enis; Kosan, Murat; Erinanc, Hilal; Gonulalan, Umut; Oguzulgen, Ahmet Ibrahim; Coskun, Esra Zeynep; Ozkardes, Hakan; 26944325Angiogenesis is an important factor in the development and progression of prostate cancer (PCA). We aimed to investigate the values of vascular-endothelial-growth-factor (VEGF) expression level and microvessel density (MVD) in the prediction of PCA diagnosis at repeated prostate biopsy (re-PBx). We retrospectively evaluated 167 patients with re-PBx according to elevated prostate-specific antigen levels, suspicious digital rectal examination, and the presence of premalignant lesions. Patients with PCA on re-PBx were included in the cancer group (n = 17). Patients with benign prostatic hyperplasia or normal tissues on re-PBx were included in the control group (n = 21). The groups were compared according to the expression level of VEGF and MVD in initial prostate biopsy. There was no statistically significant difference between groups according to age and serum prostate-specific-antigen values. The mean VEGF scores of the cancer and control groups were 232.64 +/- 11.14 and 183.09 +/- 14.56, respectively (p < 0.05). The mean MVD of the biopsy samples in the cancer and control groups were 246.47 +/- 17.59 n/mm(2) and 197.33 +/- 16.26 n/mm(2), respectively (p < 0.05). The cutoff values of VEGF scores and MVD were set as 200 and 215, respectively, for PCA detection in our study. Our results showed that the expression level of VEGF and MVD significantly increased in the initial prostate-biopsy samples of patients with PCA diagnosed with re-PBx. The evaluation of VEGF expression level and MVD might have an important value in the prediction of PCA at re-PBx. The expression level of VEGF and MVD should be kept in mind as PCA-related histopathological changes that indicate the increased angiogenesis in prostatic tissue.

Because of potentially malignant findings on ultrasonography and during clinical examination, the patient underwent an excisional biopsy. Histologically, the lesion was composed of spindle to round shaped cells arranged in short bundles in a storiform pattern. Immunohistochemically, the cells were positive for vimentin and SMA and negative for desmin, S100, and CD34. Based on these morphological and immunohistochemical features, a diagnosis of nodular fasciitis was made. We emphasize that nodular fasciitis of the breast may showclinical features and imaging findings similar to those of breast cancer. The histopathologic diagnosis of nodular fasciitis can also be challenging. The purpose of this case report is to highlight the characteristics and the differential diagnosis of this rare neoplasm.Item Recurrence of Primary Vascular Leiomyosarcoma Five Years after Initial Diagnosis in the Lower Extremity(2018) Erinanc, Hilal; Ozulku, Mehmet; Terzi, Aysen; 0000-0003-1401-6356; 0000-0002-1225-1320; 29971175; AAL-1268-2021; F-7546-2013Primary leiomyosarcomas of vascular origin are rare tumors. They frequently arise within the inferior vena cava; however, the peripheral vein was also affected. To date, only a few hundred cases have been reported in the world literature. Although it is an extremely aggressive tumor, the symptoms may be unspecific, especially in the lower extremities. In this report, we present a case of primary vascular leiomyosarcoma, arising from the short saphenous vein, with symptoms mimicking thrombus in the initial diagnosis. The diagnosis of leiomyosarcomas was confirmed by standard H&E staining and immunohistochemical staining. Recurrence of the tumor has been observed five years after surgical treatment. Due to its rarity, experience in the management of this type of tumor is limited. The mainstay of treatment for these tumors is complete surgical resection. The purpose of the presented case is to discuss the clinicopathological features and management options of this tumor, under the light of the most recent literatures.
