title: Leiomyosarcoma arising in atypical fibromuscular hyperplasia (phyllodes tumor) of the prostate with distant metastasis.
abstract: An extremely rare neoplasm of the prostate, commonly known as phyllodes type of atypical prostatic hyperplasia, is described in a 57-year-old man. Over a 2-year period, the atypical smooth muscle component has transformed into leiomyosarcoma, and eventually metastasized to the bones and the lungs. Such an evolution has never been documented for this tumor.
