Abstract

Lipoma arborescens is an infrequent cause of long-lasting arthritis affecting a single joint, with few cases reported in the literature. Although it commonly appears in the knee, instances have been observed in other joints such as the wrist, shoulder, and elbow. This condition is marked by widespread villous proliferation and the replacement of sub-synovial tissue with mature adipocytes. The use of magnetic resonance imaging (MRI) aids in refining and precisely identifying the potential diagnosis.
