title: Primary extraskeletal Ewing's sarcoma/primitive neuroectodermal tumor of breast.
abstract: Extraskeletal Ewing's sarcoma (EES) is a rare soft tissue tumor that is morphologically indistinguishable from skeletal ES. We report a case of a 25-year-old female with recurrent EES/primitive neuroectodermal tumor of right breast with imaging findings on mammogram, ultrasound, magnetic resonance imaging breast, and positron emission tomography-computed tomography.
