[Breast metastases from embryonal rhabdomyosarcoma: apropos 2 cases and a review of the literature].
The presence of breast metastases is uncommon in oncology. In children and young adults, the most common type of primary tumour is rhabdomyosarcoma, and primary breast rhabdomyosarcomas are exceptional. Two cases are reported of breast metastatic rhabdomyosarcoma in two adolescents with several atypical characteristics in their presentation forms: the embryonal variety and the primary location at maxillary sinus. The cases reported in the literature up to now were reviewed, with a special emphasis on epidemiologic, clinical, diagnostic, and therapeutic data of this rare entity.
