title: Synovial sarcoma of the hand.
abstract: We report on a 23-year-old woman with a poorly differentiated synovial sarcoma on the palm of her hand which presented as a painless nodule. The MRI findings are presented along with the clinical and pathologic features. Because of similar morphological features, these tumors can be confused with benign lesions such as aggressive fibromatosis or ganglion cysts, especially when very small. The possibility of a synovial sarcoma mimicking a benign lesion needs to be considered when the mass does not have an unequivocal benign diagnosis on MR imaging. Following wide resection and reconstruction, our patient has been disease free with good function for 28 months.
