| Abstract |
|
Mesoblastic nephroma is an uncommon congenital tumor of infancy that rarely occurs in adults. We report an adult case of mesoblastic nephroma. A 38-year-old man was incidentally found to have a right renal mass by abdominal ultrasonography. Computerized tomography revealed a relatively homogeneous tumor with hypervascularity. Radical nephrectomy was performed. The tumor was an encapsulated whitish-yellow and myxoid solid mass. Microscopically, the tumor was composed of spindle cell proliferation. Atypia and mitosis were not identified. Among the tumor cells, there were tubular arranged epithelial components. Mesoblatic nephroma is benign, so that survival following nephrectomy alone is excellent but local recurrence and metastases have been reported. Regular postoperative follow-up is mandatnry. |
