Sacral Chordoma with Bilateral Inguinal Lymph Node Metastasis and Metachronous Tumor of the Clivus: A Case Report.

INTRODUCTION: Chordoma is a malignant neoplasm that arises from notochord remnants. Its incidence is highest above the age of 50 and behaves as a locally aggressive tumor with a slow growth rate. In most cases, complete surgical resection followed by radiotherapy offers the best chance of control. Developing metachronous tumors or distant metastasis is uncommon. CASE REPORT: A 56-year-old male patient of sacral chordoma was treated by surgery and radiotherapy. He developed later bilateral inguinal lymph node metastasis and metachronous clivus chordoma. CONCLUSION: Chordomas are rare. Multiplicity of primary disease and distant metastasis could happen, so regular follow-up is warranted and more effective therapeutic modalities are needed.
