1/3. Nephron-sparing surgery for multilocular cyst of the kidney in a child.Multilocular cyst of the kidney is an uncommon benign renal neoplasm. Because of its benign nature, this lesion is best managed by nephron-sparing surgery. This report describes a child who underwent a partial nephrectomy for a multilocular cyst of the kidney. After reviewing other cases, we discuss the clinical characteristics of multilocular cyst of the kidney and emphasize the cystic partially differentiated nephroblastoma as a differential diagnosis.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/3. Correlation of radiological and clinical features of metanephric neoplasms in adults.The main objective was to determine the clinical and radiological features of metanephric neoplasms. The tumors were diagnosed on histopathological examination. The clinical data and imaging features were retrospectively analyzed. Between 1998 and 2003, 3 patients underwent radical nephrectomy for renal masses turning out as metanephric neoplasms on histopathology. Two of these tumors were metanephric adenoma (MA) and one was metanephric adenofibroma (MAF). Clinical and radiological features were reviewed. All patients were adult females who presented with flank pain. Tumor was detected on screening ultrasound as a hyperechoic lesion. In all cases CT showed a hyper-attenuating exophytic lesion with cystic areas that enhanced with IV contrast. Based on combination of clinical and imaging features it may be possible to prospectively identify metanephric neoplasms and thus avoid unnecessary radical nephrectomy in favor of conservative surgery.- - - - - - - - - - ranking = 7keywords = neoplasm (Clic here for more details about this article) |
3/3. Papillary thyroid cancer with an initial presentation of abdominal and flank pain.PURPOSE: Well-differentiated thyroid cancer typically presents as a thyroid mass. Common sites of metastases upon presentation include cervical lymph nodes, lung, and bone. Well-differentiated thyroid cancer with clinically apparent kidney metastases is rare, with fewer than 20 cases reported in the literature. In the vast majority of these cases, the patients had known thyroid neoplasms at the time the renal metastases were identified. We report a case of papillary thyroid carcinoma that presented with abdominal pain in a 25-year-old woman with no previous history of thyroid disease. STUDY DESIGN: This study is a case report. RESULTS: The patient underwent radical nephrectomy for a right renal mass, which was diagnosed as papillary thyroid carcinoma follicular variant. During subsequent evaluation, metastatic disease was also identified in the patient's lungs. The patient was treated with total thyroidectomy and iodine 131. CONCLUSIONS: Papillary cancer, which ordinarily behaves in an indolent manner, can have unusual presentation, including disseminated metastasis on presentation. Renal metastases are extremely rare.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
