title: Giant undifferentiated oropharyngeal sarcoma: a case report and review of the literature.
abstract: We report on a patient who presented to the Ear, Nose and Throat (ENT) clinic with swelling of the neck, dysphagia, headache, dyspnea and stridor. Imaging studies revealed an expansive heterogeneous process to the left retropharyngeal region. The mass was ovoid in shape, displaying moderate enhancement after intravenous contrast administration. Subsequently, a biopsy revealed the presence of undifferentiated sarcoma. The patient was treated with chemotherapy followed by radiation therapy, but follow-up exams at 6 months posttreatment revealed that while the tumor was stable, it persisted. Consequently, the patient was enrolled in a palliative care and pain control program and is currently being followed.
