  • Abstract
  • Look Inside

 A 70-year-old woman who was previously diagnosed as having lipoma or liposarcoma and recurred five times after excision in the last 30 years is reported.

 Histologically, the tumor was diagnosed as lipoma until the fourth excision was done and diagnosed as well differentiated liposarcoma during the fifth and sixth excision.

 However, the tumor was found to have the same histological findings when reexamined in detail.According to the WHO classification, it was classified as well differentiated lipoma-like liposarcoma, although a decision was made to classify the tumor as atypical lipoma according to the classification proposed by Kindblom and Evans.

 In the sixth operation, a parapharyngeal tumor was excised by the transcervical approach with mandibulotomy.
