A Parapharyngeal Soft Tissue Chordoma Presenting with Synchronous Cervical Lymph Node Metastasis: An Unusual Presentation

Abstract

A 63 year old male presented with a three month history of dysphagia, neck swelling and an oropharyngeal swelling on examination. Initial fine needle aspiration cytology and magnetic resonance imaging (done at a peripheral hospital) suggested a salivary gland neoplasm with lymph node metastasis. An infra-temporal approach was employed to excise the tumour mass and a modified radical neck dissection undertaken to remove the cervical metastasis. Histopathological examination with immunohistochemistry confirmed this to be a soft tissue chordoma. To the best of our knowledge, this is the first documented report of an extra-axial soft tissue chordoma presenting with synchronous metastatic disease. Though rare, this adds to the list of differential diagnoses for complex parapharyngeal lesions. A multidisciplinary approach between head and neck surgery, histopathology, radiology and sarcoma teams is paramount for arriving at the correct diagnosis and to deliver optimal treatment.
