[Liposarcoma of the infratemporal fossa. Apropos of a case].

The authors report about one female patient with a liposarcoma of the right infratemporal fossa. Such tumors are rare, making up 10 to 12% of all soft-tissue sarcomas. Their occurrence in a cervical site is rare, unlike that in the inguinal region, the retroperitoneum or the lower limbs. Their diagnosis is mainly established by the histopathological study. Computed tomography and magnetic resonance imaging are particularly useful to choose the surgical approach. The technique chosen for this infratemporal tumor was a transmandibular cervical approach. Evolution was favorable, and the patient has currently had no reoccurrence after two years.
