영남대학교 의과대학 성형외과학교실에서 흔히 사지의 골격근내에서 발생되는 intramuscular lipoma중 매우 드물게 관골부 근육에서 발생된 근육내지방종 1례를 치험하였다. 근육내지방종은 성숙된 지방세포가 위축되어 있는 근육속에 불규칙하게 생기는 양성종양으로 지방종의 완전절개만이 재발을 방지하고 완치 시킬 수 있는 유일한 치료방법이다.
Lipomas are common soft tissue tumor that are usually located in the subcutaneous tissue. And intramuscular lipomas commonly arise in the upper and lower extremities, where they usually involve the large muscles. Intramuscular lipoma, also referred to as an infiltrating lipoma. is an unusual benign slow growing tumor composed of mature fat cell interdigitating with skeletal muscle. However, intramuscular lipomas are exceedingly rare in the face. We have been experienced a case intramuscular lipoma that located in the malar area. Because of the rarity of these tumors and their propensity to recur without adequate surgery, the case report is presented here. Achievement of surgical margin is essential as the recurrent rate may be as high as 15% to 62.5% without complete excision.
