Myxoma of the Kidney Associated with Hemorrhage

Myxomas are relatively rare tumors and most of them occur in the heart, skin, and soft tissues and bones. Renal myxomas are extremely rare neoplasms and very few cases have been reported in the literature. A review of medical literatures reveals no previous description of renal myxoma complicated with extensive areas of hemorrhage. So, we report such a case in a 43-year-old female. She had a left renal mass incidentally discovered during ultrasonography at a regular health checkup, and further computed tomography scan showed 4.9 × 3.1 cm mass with circular septal enhancement and ill-defined margin with the left psoas major muscle. Radical nephrectomy was performed because of suspected malignant renal tumor. Postoperative histopathology of resected specimen revealed the typical appearance of a myxoma associated with extensive hemorrhage.
