Liposarcoma is a very rare tumor in the head and neck region. Approximately 3-6% of all liposarcomas occur in the head and neck region. They usually present as a slowly growing, painless mass
lesion. Imaging studies usually reveal, depending on the differentiation of the tumor, a variable amount of intralesional fat (

Fig. 2).
The preferred treatment is wide surgical resection.
