Abstract

Lipoma arborescens is a rare intra-articular lesion consisting of villous lipomatous proliferation of the synovium that tends to occur in the knee joint, especially in the suprapatellar pouch. The lesion has been observed in other locations, including the glenohumeral joint, subdeltoid bursa, hip, and elbow. We report a case of a lipoma arborescens of a unilateral hip joint in a 34-year-old man. MRI and a whole body bone scan were performed. In addition, a surgical synovectomy was performed and microscopic examination of the tumor revealed multiple variable-sized villous masses composed of mature fat tissue and lined by synovial cells which confirmed the diagnosis of lipoma arborescens.

수목상지방종은 활액막의 융모성 지방 증식을 동반한 드문 관절 내 병변으로 슬관절 주위, 특히 상슬개골와에 생기는 경향이 있다. 이 병변은 다른 부위, 예컨대 견관절, 삼각근하낭, 고관절 그리고 주관절 등에서도 관찰될 수 있으나 매우 드문 편이다. 우리는 34세 남자환자에서 편측으로 발생한 수목상지방종 증례를 보고한다. MRI와 전신 골주사검사가 시행되었고 수술적 활액막 제거가 이루어졌다. 병리조직학적 검사에서 수목상지방종으로 진단되었다.
