Pleomorphic liposarcoma of the head and neck: Presentation of two cases and literature review

Background: Pleomorphic liposarcoma(PL) is an exceedingly rare tumor of the head and neck. This aggressive liposarcoma variant portends a poorer prognosis compared to more typical sarcomatous tumors. Methods: Multi-institutional study including two cases of PL, the first case occurring in the post-auricular region and the second in the cheek with later recurrence within the parotid bed. Results: Both patients were treated surgically with wide local excision. One patient required reoperation to obtain negative margins. The other patient underwent a total parotidectomy with neck dissection for recurrent intraparotid nodal disease. Both patients underwent adjuvant radiotherapy. No patient had evidence of recurrent disease with minimum one year follow-up. Conclusion: Although the literature is sparse on this disease, wide surgical extirpation with negative margins and adjuvant radiation is recommended. Increased reports of this pathology can be helpful in providing practitioners with experienced -based information that can aid in early detection and treatment. We present the first case series of PL of the head and neck in the literature.(C)2017 Elsevier Inc All rights reserved.
