Abstract

Although liposarcoma is the second most common soft tissue sarcoma in adults, the incidence of liposarcoma in the head and neck is low. The histologic nature of liposarcoma is correlated clinically with treatment outcome, but histologic classification of liposarcoma is controversial. Well-differentiated liposarcoma and atypical lipoma are pathologic synonyms because they are identical lesions both morphologically and karyotypically. They represent the lowest grade lesions in the spectrum of liposarcoma. The terms "atypical lipoma" were introduced specifically to describe well-differentiated liposarcomas occurring in the extremities, because of their better prognosis in comparison with their retroperitoneal counterparts. We present 1 case of atypical lipomatous tumor of the neck.
