Background The Ewing sarcoma family of tumors comprises a group of high-grade small round cell tumors, including Ewing sarcoma of bone, extra-skeletal Ewing sarcoma, peripheral primitive neuro-ectodermal tumor (PNET), and Askin tumor (thoraco-pulmonary PNET). They are more prevalent in young children and adolescents. Ewing's Sarcoma is an aggressive tumor majorly described in bones. Primary renal Ewing's sarcoma is an extremely rare entity, characterized by a very aggressive course, with very few reported cases in the literature. Case presentation We present an 18-year-old girl who presented with sudden onset left flank pain and hematuria. The patient had histopathology-proven primary renal Ewing's sarcoma, which was initially misdiagnosed as renal cell carcinoma on imaging. Conclusions Owing to its non-specific radiological appearance, a high index of suspicion and a systematic approach is essential for detection of renal Ewing’s Sarcoma.
Introduction: Aorto-iliac Occlusive Disease (AIOD) involves the infra-renal aorta and the iliac arteries. Recent studies advocate endovascular management in TASC C and D lesions also. It involves balloon angioplasty with or without stent deployment.5 The aim of this retrospective study is to evaluate the results of endovascular balloon angioplasty and primary stenting in patients of AIOD. Methods: Twenty-five patients with Aorto-iliac occlusion disease who met the inclusion criteria during 1-year study period were included. Patients with acute thrombosis, abdominal aorta or iliac artery aneurysm and additional common femoral artery occlusion were excluded. The TASC II classification was used to define the characteristics of the lesions. The baseline data, procedural details and follow-up results were analysed. Results: Amongst 25 patients studied, age ranged from 40-75 years. Self-expanding metallic stent was employed in all patients. Technical success following primary stenting was achieved in all patients. Procedural times for TASC-II A, B, C and D lesions were 90+ 30, 110+ 40, 135+35 and 155+ 45 minutes, respectively. During follow-up, the cumulative primary patency rates at 1 month and 6 months were 100%. Cumulative primary patency rates at 1 year were 91.67%. Conclusion: Short- term outcomes of balloon angioplasty and stenting for Aorto-iliac artery occlusions in terms of primary patency rates were excellent.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
