Liposarcoma of the tongue: case report and literature update

Liposarcoma is an exceedingly rare tumor in the oral cavity. We report a case of a 70-year-old man with liposarcoma that presented as a lump on the tongue. The excised tumor was diagnosed as a well-differentiated lipoma-like liposarcoma. The majority of cases of well-differentiated liposarcoma follow a relatively benign course, but the disease has a high recurrence rate. It appears that accurate clinical and histopathologic diagnosis of this lesion is difficult. The prognosis seems to depend on the histologic type, size, and location of the lesion. Wide surgical excision is important for successful management of these liposarcomas.
