title: Sarcomatous change in granulosa cell tumor.
abstract: Granulosa cell tumors have a tendency for indolent growth and late recurrence. The present case of granulosa cell tumor in a 67-year-old woman is the first, to the authors' knowledge, to be reported as showing sarcomatous transformation with a rapid fatal course. Both the granulosa cell and fibrothecomatous elements appear to have undergone sarcomatous change with some evidence to suggest rhabdomyosarcomatous differentiation. The sarcomatous component was present in metastatic deposits.
