title: [A case report of phylloides tumor of the prostate: review of the literature and analysis of bizarre giant cell origin].
abstract: A case of phylloides tumor of the prostate in a 58-year-old male is presented. The tumor was composed of columnar cystic folds and pleomorphic stromal elements including bizarre giant cells. Electron microscopic examination, which was performed using specimens embedded in paraffin blocks, revealed that the bizarre giant cells originated from the smooth muscle. The postoperative course was uneventful, with no evidence of local recurrence or metastasis for more than 2 years after operation.
