 Liposarcomas are rare malignant mesenchymal neoplasms in the head and neck region, especially in the parotid gland. Based on a thorough search English literatures, there were only 6 cases reported.

 A 47-year-old man presented with a pre-auricular tumor in the right side and subsequently he underwent the right partial parotidectomy. The histopathological findings revealed the presence of atypical and hyperchromatic stromal cells, and varying number of mono- or multi-vacuolated lipoblasts. Finally the diagnosis was made as well differentiated liposarcoma. There was no recurrence in 5 years postoperatively.
