Pleomorphic Liposarcoma of the Parapharyngeal Space: A Rare Case Report

Pleomorphic liposarcomas (PLS) are the rarest subtype of liposarcomas, representing only 5-10% of liposarcomas. Pleomorphic liposarcomas are extremely aggressive and have a poor prognosis. Here, we present the case of a 66-year-old female who presented with difficulty swallowing, talking, and hearing. An extensive investigation revealed the presence of an aggressively growing parapharyngeal space mass. The patient underwent a left parapharyngeal space exploration and left deep lobe parotidectomy by the cervicoparotid approach. Histopathological evaluation of the surgical specimen further confirms the presence of pleomorphic subtype of liposarcoma. The patient received adjuvant radiotherapy following the procedure. At 6 months postop, the patient is in good health and shows no evidence of recurrence. In addition to this treatment, we discuss the radiologic and histologic findings of this current case.
