Urothelial neoplasms in patients younger than 20 years old are extremely rare, and there is no established etiology, treatment guidelines, or surveillance for urothelial carcinoma in the pediatric population. A 17-year-old boy who presented with gross hematuria showed a smooth, round mass on the left lateral wall of the urinary bladder on cystoscopy. Histologic examination showed low grade papillary urothelial carcinoma of the urinary bladder without muscle layer invasion. We report a case of papillary urothelial carcinoma of the urinary bladder in a pediatric patient treated with transurethral resection.

In mitral valve disease, mural thrombus in the left atrium is common, particulary in the atrial appendage in patients with atrial fibrillation. Occasionally, the angiographic sign of "neovascularity" and "fistula" in the region of the left atrial appendage during coronary arteriography has been reported to indicate the presence of thrombus in the left atrium, which might not even be revealed by transthoracic two-dimensional echocardiography. We observed coronary neovascularity and fistula formation in two pateints with mitral stenosis and these findings were due to organized mural thrombus that was adherent to the wall of the left atrial appendage. So we report 2 cases with brief review of literature.
