Lipoma arborescens (diffuse articular lipomatosis).
Lipoma arborescens (LA) (diffuse articular lipomatosis, synovial lipomatosis, Hoffa disease) is a rare intra-articular lesion of unknown etiology. This article presents three patients who had LA, which was diagnosed in the knee in two patients and in the wrist of the third patient. Details of the clinical and histomorphological examination and treatment, in addition to a review of the literature, are discussed. The article concludes that in patients with a slow increase in painless swelling of the joints, unresolving articular pain with or without limited motion, or intermittent effusions following a minor trauma, LA should be considered in the differential diagnosis. It should be remembered that LA occurs in joints other than the knee, such as the elbow, shoulder, and wrist. Although recommended surgery involves arthrotomy and synovectomy, arthroscopic synovectomy may be a useful treatment modality, particularly in the larger joints as the recurrence rate is low.
