title: Malignant transformation of polyostotic fibrous dysplasia.
abstract: We have described an unusual case of polyostotic fibrous dysplasia in a 25-year-old white woman who had malignant transformation into a mesenchymal tumor with widespread metastases and features of rhabdomyosarcoma. Masculinization also occurred with high plasma testosterone levels. A mechanism for the development of masculinizing features is discussed.
