Pre-Sacral Chordomas, about Two Cases and Review of the Literature

Abstract

The World Health Organization (WHO) defines chordoma as a malignant tumor of intermediate or low grade, developing at the expense of embryonic remnants of the notochord. These tumors represent 8.4% of all malignant bone tumors. We report 2 cases collected in the medical oncology department at the CHU Hassan II in Fes. In whom the clinical examination revealed a mass and/or signs of loco-regional compression. The tumor was located in the sacrum in both patients. The diagnosis was based on the data of the anatomopathological examination showing the association of a lobulated architecture with classic physaliphore cells and a mucoid intercellular substance. Immunohistochemistry was performed for both patients. The principle of therapeutic management was based on radiotherapy and targeted therapy since surgery was difficult given the local tumor extension.
