Chordoma of the Oropharynx.

Abstract

Background: Chordoma is a rare malignant neoplasm that predominantly arises from the axial skeleton, but can also develop in unusual locations. However, there are also rare cases of "NOS" chordoma involving the oropharyx and epithelial-myoepithelial carcinoma of the parotid gland in the same patient. According to contemporary research, chordoma is a rare malignant neoplasm that arises from the embryonic remnants of the notochord. and typically involves the clivus, sacrococcygeal bones or vertebrae. Studies have shown that the incidence of chordoma has been estimated to be one per one million people per year. Chordoma can occur at any age, but most commonly it is diagnosed in the 40-60 year old age group with the male predominance.

Objective: The aim of this article was to review the case of a 74-year-old female patient with epithelial-myoepithelial carcinoma of the parotid gland and a case of "NOS" chordoma involving the oropharyx.

Methods: Diagnostic methods were used to examine a female patient with two primary malignant tumors: CT neck scan, CT of paranasal sinuses, ultrasound examination, scintigraphy and operative finding.

Case presentzation: Due to the anatomy complexity, complete resection of the tumor through a transoral-transpharyngeal approach was not possible. Intraoperative palpation of the mass revealed well defined submucosal lesion 20x43x46mm beginning at the level of the oro- and hypopharynx and extending superiorly to the nasopharynx, and posteriorly into the spinal canal and intervertebral foramen causing near complete occlusion of the oro and hypopharynx. The patient also underwent extracapsular dissection of the parotid tumor. Postoperative palliative radiotherapy was performed.

Conclusion: Surgical treatment remains the mainstay of treatment for EMC and radiation is imperative for patients who refuse surgery and for those with advanced or inoperable diseases.
