title: Liposarcoma of temporal bone: a case report.
abstract: This is the third case report of liposarcoma of the temporal bone. A 69-year-old man complained of left otalgia, left otorrhea, and dizziness for several months, with a past history of tympanoplasty for cholesteatoma 28 years previously. Otoscopy revealed debris in the attic. We performed tympanoplasty for recurrent cholesteatoma. The postoperative pathological diagnosis was well-differentiated liposarcoma. Palliative resection of liposarcoma was performed 3 months after the first surgery. Neither local recurrence nor distant metastasis has been detected for 24 months after the first surgery. The favorable outcome in this patient was probably due to the histological type of his liposarcoma.
