Myxoma of the kidney.
ABSTRACT A 62-year-old man had a right renal mass incidentally diagnosed by ultrasonography. Magnetic resonance imaging revealed a well-defined right renal mass with homogenous low-signal intensity on the T(1)-weighted pulse sequence and heterogeneous high-signal intensity on the T(2)-weighted pulse sequence. A right nephrectomy was performed. The histological examination showed a myxoma, which is a very uncommon neoplasm in the kidney. Eight cases have been reported previously.

ABSTRACT: Myxomas are uncommon soft-tissue neoplasms, which are extremely rare in the kidney. In the present case, a right nephrectomy was performed because of suspected presence of a malignant renal tumor. In the macroscopic examination, the kidney contained a well-circumscribed, yellowish, and gelatinous tumor. The tumor was measured 6 cm in diameter. It was composed of fibroblast-like, slender spindle cells with myxoid stroma. With these histopathological findings, the case was diagnosed as renal myxoma. The case was discussed in the light of literature.Turkish Journal of Urology. 01/2010;
