UNLABELLED Primary pure ovarian leiomyosarcomas constitute a malignant subgroup of ovarian smooth muscle tumors which comprise only 1% of ovarian tumors. Their origin, etiology, histologic features, clinical behavior, and optimal treatment are still obscure. Malignant behavior is almost always associated with any 2 of coagulative necrosis, cellular atypia,(More)
Benign multicystic peritoneal mesothelioma is a rare tumor that occurs mainly in women in their reproductive age. It is characterized by the formation of multiple, thin-walled, multilocular cysts that frequently produce large, intra-abdominal masses. The short follow-ups and possible etiologies based on the published reports make it difficult to draw any(More)
The aim of this study was to determine the effects of pentoxifylline (Ptx) in reperfusion injury of the small bowel as a leukocyte stabilizer, free radical scavenger, and microcirculatory regulator. Ninety-six male Sprague-Dawley rats were used to determine the biochemical, histopathologic and blood flow changes of the reperfused small intestines after 30(More)
BACKGROUND Interventions that reduce the generation or the effects of reactive oxygen species exert beneficial effects in a variety of models of septic shock. We investigated the effect of tempol, a low-molecular-weight membrane-permeable radical scavenger, on mesenteric blood flow and organ injury in a murine cecal ligation and puncture (CLP) model of(More)
Congenital granular cell tumor, also known as congenital epulis, is a very rare lesion seen in newborns. The typical presentation is a solitary nodule occurring on the gingiva of the anterior alveolar ridge of either jaw. Multiple-site involvement is seen very seldom but has been noted on the same or different alveolar ridges. However, tongue involvement is(More)
OBJECTIVE It has been reported in recent studies that nephron-sparing surgery (NSS) is as effective as radical nephrectomy (RN) for pT1a and pT1b renal cell carcinoma (RCC). In order to decrease the rate of tumor recurrence, resection of a small amount of normal parenchyma surrounding the tumor is widely recommended. Although a 0.5-1.5-cm wide resection(More)
PURPOSE The scar tissue that forms after lumbar dissection is a severe complication and a cause of lumbar and radicular pain. It was recently shown that radiotherapy could inhibit peridural fibrosis after laminectomy. In this study, the efficiency of external irradiation was compared with spinal membrane application. METHOD AND MATERIALS Thirty male New(More)
Primary renal non-Hodgkin's lymphoma is very rare in childhood. A six-year-old boy presented with bilateral non-obstructive multinodular nephromegaly and renal failure. Percutaneous needle biopsy showed large-cell lymphoma. The patient was started on chemotherapy. A right nephrectomy was done when systemic hypertension developed in the presence of a(More)
