Abstract

Liposarcoma is one of the most common malignant mesenchymal neoplasm, comprising approximately 15% of all soft tissue sarcoma. This is a tumor with an incidence peak between age 40 and 60 years, and is slightly more common in men than women. Although all body region may be involved, the most frequent sites are lower extremities and retroperitoneum but rare in the head and neck region. Liposarcoma can be classified to four subtypes ; myxoid, well-differentiated, round-cell, pleomorphic. The myxoid type is the most common and accounts for almost one half of all liposarcoma. Wide surgical excision with or without radiation therapy has been used to manage this lesion. We report a case of 50-year old man with soft tissue swelling on the left cheek, previously diagnosed as myxoid liposarcoma in the left lower extremity. After radiologic and ultrasonic study and surgical excision with biopsy, the lesion of cheek was diagnosed as myxoid liposarcoma with round cell differentiation.

지방육종은 주로 근간 간엽조직으로부터 발생되어지며, 중년이상의 남성에서 호발하고 주된 발병부위는 하지 및 후복막강이고 구강 주위조직에 이환되는 경우는 극히 드문 악성종양이며, 본 증례에서는 4년 전 좌측 하지에서 발생되어 우측 하지 및 좌측 협부에 전이된 것으로 생각되어지는 점액양의 지방육종으로 종물의 외과적 절제술 및 화학요법을 시행하였고 장기적인 관찰이 요구된다.
