Publication Metadata only Granulosa cell tumor presenting with ovarian torsion and de novo borderline mucinous ovarian tumor in the contralateral ovary.(2015-01-01) ATES, SEDA; Sevket, OSMAN; SUDOLMUS, S; SONMEZ, FATMA CAVİDE; DANSUK, RAMAZAN; ATEŞ, SEDA; ŞEVKET, OSMAN; SÖNMEZ, FATMA CAVİDE; DANSUK, RAMAZANPublication Metadata only Malignant Brenner Tumor Of The Ovary Invading The Sigmoid Colon(2016-09-01T00:00:00Z) GÖKMEN KARASU, AYŞE FİLİZ; KIRAN, Gürkan; SÖNMEZ, FATMA CAVİDE; KUNDUZ, ENVER; GÖKMEN KARASU, AYŞE FİLİZ; KIRAN, GÜRKAN; SÖNMEZ, FATMA CAVİDE; KUNDUZ, ENVERPublication Metadata only Search for the G spot: microvessel and nerve mapping of the paraurethral anterior vaginal wall(2020-06-01T00:00:00Z) AYDIN, SERDAR; SÖNMEZ, FATMA CAVİDE; GÖKMEN KARASU, AYŞE FİLİZ; GÜL, Burcu; Arioglu, Cagri; AYDIN, SERDAR; SÖNMEZ, FATMA CAVİDE; GÖKMEN KARASU, AYŞE FİLİZ; GÜL, BURCUIntroduction and hypothesis Orgasm and other sexual responses such as pain, arousal and lubrication may be mediated by nerve fibers and vessels in the lamina propria and muscularis of the vaginal wall, in which case the number of nerve fibers and vessels would be associated with sexual functions. The aim of the study is to map the distribution of nerves and vessels in the anterior vaginal wall along the paraurethral region in a systematic fashion. Methods Specimens were taken from women with anterior vaginal wall prolapse undergoing colporrhaphy anterior repair. All specimens were mapped in a standard way starting 15 mm proximal to the external urethral orifice. Selected blocks of samples were immunohistochemically stained: actin, smooth muscle Ab-1 and S100 Protein Ab-1. The numbers of microvessels and nerves in the lamina propria and muscularis were counted in five consecutive high-power fields of a light microscope. Pairwise comparisons of proximal, distal, right and left paravaginal microvessel and nerve fiber density were analyzed with paired-sample t-test or Wilcoxon signed-rank test. Results Vaginal nerve fibers in the lamina propria and muscularis have a fairly even distribution in the anterior vaginal wall. Vaginal small vessel vascularization and microvascularization are also evenly distributed, with no concentrated site along the paraurethral region of the anterior vaginal wall. Conclusions Nerve fiber, nerve bundle, microvessel and small vessel densities in the lamina propria and muscularis were fairly regular, with no concentrated site on the paraurethral region of the anterior vaginal wall.Publication Open Access Vulvar granular cell tumor(2016-07-01) Sonmez, FATMA CAVİDE; KOROGLU, Nadiye; Guler, BERİL; Arici, DİLEK SEMA; SÖNMEZ, FATMA CAVİDE; GÜLER, BERIL; ARICI, DILEK SEMAGranular cell tumors (GCTs) are rare and approximately half of the all lesions arise from head and neck, especially from the tongue. However, they are rarely seen in the vulva. They can occur in patients of any age, but peak age incidence is in the fourth to sixth decades. They generally occur as small, slow growing, and skin-colored nodule. GCTs are usually benign, but malignant cases were reported. Recurrence can be seen in benign tumors with clear margins, but rates increase with positive margins. The treatment is complete surgical excision. We report a case of benign GCT of the vulva. A 41-year-old patient presented with vulvar mass, and biopsy was consisted with GCT.Publication Metadata only Sinir ve Damar Kökenli Yumuşak Doku Sarkomları(2018-01-01) GÜRKAN, VOLKAN; SÖNMEZ, FATMA CAVİDE; ATASOY, SEZEN; GÜRKAN, VOLKAN; SÖNMEZ, FATMA CAVİDE; ATASOY, SEZENKötü huylu sinir kılıfı tümörleri; Kötü huylu periferik sinir kılıfı tümörü (MPSKT), Kötü huylu granüler hücreli tümör ve Ektomezenkimoma olarak sınıflandırılmaktadır. MPSKT dışındaki tümörler oldukça ender görülmektedir. MPSKT, tüm yumuşak doku sarkomları içerisinde %5 gibi küçük bir orana sahiptir. Tipik olarak 20-50 yaşları arasında görülür ve kadınlar erkeklere oranla daha fazla etkilenmektedir. Alt ekstremiteler lezyonların en sık rastlandığı yerlerdir. Çoğu MPSKT siyatik sinir gibi büyük periferal sinirleri tutar. Hastalarda gittikçe büyüyen kitle varlığıyla beraber nöropatik semptomlar da gözlenebilir. Görüntülemede manyetik rezonans (MR) öncelikli tercihtir. Kötü huylu damar tümörleri ise damar endotelinden kaynaklanan lezyonlardır. Tüm yaşlarda görülmesine rağmen yedinci dekatta daha sık rastlanırlar. Çoğu olguda etyoloji belirsizdir ancak bazı vakaların radyasyonla ilişkili olduğu bilinmektedir. Sıklıkla alt ekstremitelere lokalizedir. Dünya Sağlık Örgütü (WHO) kötü huylu damar tümörlerini farklı alt tiplere ayırmış olmakla beraber ön sırada "anjiyosarkom" gelmektedir. Bu tümörler oldukça agresif olup, yüksek mortalite oranına sahiptir.Publication Open Access Cotyledonoid Dissecting Leiomyoma with Symplastic Features: Case Report.(2017-08-01) SONMEZ, FATMA CAVİDE; TOSUNER, ZEYNEP; KARASU, AFG; Arıcı, DİLEK SEMA; DANSUK, RAMAZAN; SÖNMEZ, FATMA CAVİDE; TOSUNER, ZEYNEP; ARICI, DILEK SEMA; DANSUK, RAMAZANForeign bodies are rare and challenging issues leading to symptoms according to the location. Laparoscopy is a popular and minimally invasive method used for removal of foreign bodies in the abdominal cavity or retroperitoneum. We herein report a case with retroperitoneal foreign body that was removed through retroperitoneal single- port laparoscopy using nephroscope. To our knowledge this is the first case of removal of a retroperitoneal foreign body through single- port laparoscopy using nephroscope.Publication Open Access New Markers in Atherosclerosis: Thrombospondin-2 (THBS-2) and Leukocyte Cell-Derived Chemotaxin-2 (LECT-2); An Immunohistochemical Study.(2016-12-01) AKTHSR, Muhammad Salman; SÖNMEZ, FATMA CAVİDE; YILDIZ, PELİN; TANRIKULU, MEHMET AKİF; AYDIN, CEMALETTİN; KAHRAMAN AY, NURAY; SÖNMEZ, FATMA CAVİDE; YILDIZ, PELİN; AYDIN, CEMALETTİN; KAHRAMAN AY, NURAYBACKGROUND Current research investigating the role of THBS2 and LECT-2 in atherogenesis is very limited. Therefore, we designed this study to demonstrate the role of THBS-2 and LECT-2 in atherosclerosis at the tissue level in fresh specimens. MATERIAL AND METHODS A total of 32 patients who underwent coronary bypass surgery were enrolled. Aortic wall punch biopsies were obtained at the site of proximal aortosaphenous bypass graft anastomosis. A specimen of left internal mammarian artery (LiMA) was taken from the segment just proximal to its anastomosis. The aortic tissue is representive of the atherosclerotic tisue, and LiMA tissue is representative of the non-atherosclerotic area. The specimens were painted with CD68 for macrophage, and THBS-2 and LECT-2 antibodies for immunohistochemical staining. RESULTS Aortic THBS-2 levels were significantly lower, whereas aortic LECT-2 levels were significantly higher when compare to LiMA (14.4±9.9 (5-30) and 36.9±13.0 (5-60) p: 0.0001 and 20.3±15.0 (5-60) and 20.8±13,8 (10-30) p: 0.0001, respectively). CD68+ and monocyte level correlated significantly with AHA atherosclerosis grade (p=0.01, r=0.45 and p=0.001, r=0.56, Spearman's test). CD68+ level correlated significantly with LECT-2 levels in atherosclerotic aortic tissue (p=0.026, r=0.392, Spearman's test), whereas aortic TSBN-2 levels were not. CONCLUSIONS The present study has taken the first steps to highlight new markers in atherosclerosis by using immunohistochemical method. The study results suggest that the tissue levels of THBS2 and LECT-2 may correlate with the stage of atherosclerosis.Publication Metadata only Well-Differentiated Mucinous Cystadenocarcinoma of the Renal Pelvis(2014-01-01T00:00:00Z) SÖNMEZ, FATMA CAVİDE; Esen, Haci Hasan; Tavli, Lema; Kilinc, Mehmet; SÖNMEZ, FATMA CAVİDEAdenocarcinoma arising from renal pelvis is uncommon. A mucinous cystadenoma of the renal pelvis with malignant transformation is a rare entity. We report a case of well-differentiated mucinous cystadenocarcinoma of the renal pelvis with malignant transformation of cystadenoma with mucus-filled kidney (muconephrosis) due to mucin produced by the tumor.Publication Metadata only Should Core Needle Biopsy be Used in the Evaluation of Thyroid Nodules?(2016-12-01) Guler, BERİL; Kiran, TUĞÇE; Arici, DİLEK SEMA; Aysan, Erhan; Sonmez, FATMA CAVİDE; GÜLER, BERIL; KIRAN, TUĞÇE; ARICI, DILEK SEMA; AYŞAN, MUSTAFA ERHAN; SÖNMEZ, FATMA CAVİDEFine needle aspiration (FNA) is the first choice in thyroid nodules suspected of harboring malignancy on sonography in routine practice. However, sampling with core needle biopsy (CNB) is also being used, especially in cases with repeated nondiagnostic/indeterminate diagnoses. The aim of this study was the retrospective evaluation of CNB samples. A total of 604 thyroid CNB samples registered in the Department of Pathology at Bezmialem Foundation University Medical Faculty within the 1-year period between June 2014 and June 2015 were re-evaluated by correlation with previous FNA and later resection results. CNB was divided into diagnostic groups of insufficient, malignant, suspicious for malignancy, no evidence of malignancy/benign, atypia of uncertain significance (AUS)/follicular lesions of uncertain significance (FLUS), and follicular neoplasm (FN)/suspicious for follicular neoplasm (SFN). Among the 604 cases, 15 cases (2.48 %) were classified as malignant and 9 cases (1.49 %) as suspicious for malignancy. No evidence of malignancy was seen in 512 cases (84.76 %). There were 26 (4.3 %) cases in the AUS/FLUS-FN/SFN group, and the sample was inadequate in 42 cases (6.95 %). Resection was performed for 17 of the cases classified as malignant or suspicious for malignancy, and all were found to be malignant. There were also 10 resected cases with a diagnosis of no evidence of malignancy, and all were found to be benign. We think that sampling with CNB may be useful especially in repeating inadequate biopsies or cases diagnosed with AUS/FLUS that have hesitations regarding clinical management. Larger series including comparisons with FNA and resection results are required.Publication Open Access Immunoexpression of TTF-1 in Non-Lung Tumors(2014-12-01T00:00:00Z) TOSUNER, ZEYNEP; ARICI, Dilek Sema; GÜCİN, ZÜHAL; BÜYÜKPINARBAŞILI, NUR; SÖNMEZ, FATMA CAVİDE; YILDIZ, PELİN; TOSUNER, ZEYNEP; ARICI, DILEK SEMA; GÜCİN, ZÜHAL; BÜYÜKPINARBAŞILI, NUR; SÖNMEZ, FATMA CAVİDE; YILDIZ, PELİNObjective: Thyroid transcription factor-1 (TTF-1) immunoexpression is frequently determined in small-cell lung carcinomas, as well as primary lung adenocarcinomas. While dealing with metastatic carcinomas, TTF-1 immunoexpression is a significant indicator of primary lung carcinomas. Recent studies have revealed that TTF-1 immunoexpression is also defined in non-lung cancers, such as squamous cell carcinomas of different sites and certain neuroendocrine tumors. The verified data obtained from these studies indicate that a straightforward diagnosis of primary lung carcinoma in cases with positive TTF-1 immunoexpression can cause diagnostic contradictions. The aim of our study is to investigate the immunoexpression status of TTF-1 in common non-lung tumors. Methods: A total of 85 cases that were diagnosed in our institute between the years 2011-2012 were included in our study. After a review of the pathological slides prepared from these tumors [colon adenocarcinoma (n: 15), renal cell carcinoma (n: 15), prostate adenocarcinoma (n: 15), invasive papillary urothelial carcinoma (n: 15), invasive ductal carcinoma of breast (n: 15), and neuroendocrine tumors (n: 10)] TTF-1 immunohistochemistry was applied. Semiquantative evaluation based on the distribution and intensity of the staining was performed by two pathologists, respectively. Results: Positive immunostaining was evident in only 1 case of colon adenocarcinoma out of 85 cases. Conclusion: Our study demonstrated that TTF-1 immunoexpression is a very rare finding (1%) in non-lung tumors. This result provides that anti-TTF-1 is a reliable antibody in the interpretation of primary lung carcinomas. In fact, further studies with a large number of cases are needed to confirm the sensitivity and specificity of TTF-1.
