OBJECTIVES To investigate the expression of sex-specific hormone receptors in normal bladder urothelium and urothelial carcinomas (UCs) of the bladder, and to analyze clinicopathological features and survival outcomes according to receptor expression. METHODS We evaluated the clinical data and tumor specimens of 139 patients with bladder cancer (BC). In(More)
Prepubertal testicular masses are relatively rare. Sertoli cell tumors account for 2% of prepubertal testicular tumors and very few have occurred in the first decade of life. Gynecomastia can be seen in approximately 5% of patients with testicular mass. We present an 8-month-old boy admitted with bilateral gynecomastia and unilateral testicular mass.
Squamous cell carcinoma arising from a mature cystic teratoma of the ovary is a rare event representing only 1-2% of all mature cystic teratomas. Furthermore, the synchronous occurrence of a second malignancy in this setting is extremely rare. A 63-year-old woman presented with a pelvic mass which was diagnosed as a left ovarian mature cystic teratoma(More)
Proanthocyanidins are potent natural antioxidants which belong to a class of polyphenols. Proanthocyanidin-rich extracts are prepared from grape seeds. The effect of grape seed proanthocyanidin extract (GSPE) on the viability of abdominal skin flaps exposed to warm ischaemia and subsequent reperfusion were studied in 40 male Wistar rats. In the control(More)
Transitional cell carcinoma of the bladder is a rare entity in childhood. We report on a 10-year-old boy with transitional cell carcinoma of the bladder who presented with gross hematuria. Ultrasonography revealed a papillary lesion in the bladder. Cystoscopic evaluation showed a papillary lesion with a thick stalk located just above the right ureteral(More)
PURPOSE The aim of this study was to determine the role of p53, Bcl-2 and Ki-67 expression in the carcinogenesis of cervical carcinoma and aggressiveness of cervical intraepithelial neoplasia (CIN). METHODS The pathology specimens of 63 patients with a diagnosis of normal squamous epithelium (22 cases), CIN I (14), CIN II (5), CIN III (8) and squamous(More)
This paper presents the details of an experimental study of arterial anastomosis, combining suture with the cyanoacrylate tissue adhesive. At the distal end of the vessel, two parallel incisions were made, 180 degrees apart from each other, and two sutures were placed passing from the proximal end to exit from the most distal part of the longitudinal(More)
INTRODUCTION The aim of this study was to assess whether epidermal growth factor receptor (EGFR) overexpression was a significant prognostic factor in clear cell renal cell carcinoma (CRCC) and whether its prognostic significance was affected by immunohistochemical expression patterns. MATERIALS AND METHODS Immunohistochemistry was performed on 100 cases(More)
OBJECTIVES We aimed to assess various bone grafts on bone formation using bone scintigraphy and histology, especially the first study that evaluated the demineralized bone matrix (DBM) + tricalcium phosphate (TCP) + hyaluronic acid (HA) combination. MATERIALS AND METHODS A total of 44 pieces in groups of autogenous bone graft, TCP, DBM, DBM + TCP(More)
Renal angiomyolipoma (AML) is the most common benign renal mesenchymal tumors. AMLs are usually asymptomatic and frequently affect women. Only epithelioid variant has malignant potential. Although life-threatening complications related to retroperitoneal bleeding and massive hematuria are possible, it is often detected incidentally. Pulmonary embolism as(More)
