Lipoma Arborescens of the Elbow: Case Report

“…Although laboratory tests are usually normal in patients with LA, ESR and CRP levels might be elevated mildly. 1,2,5 Similarly, ESR and CRP were elevated in our patient.…”

“…Joint pain and motion restriction might develop due to intermittent effusion. 1,2,5 In our patient, the elbow was painful, swollen, and tender; in addition, joint motion was restricted. Although laboratory tests are usually normal in patients with LA, ESR and CRP levels might be elevated mildly.…”

“…1,4,7 Some researchers have proposed the hypothesis that the reason of the transformation of synovial tissue may be the chronic inflammation of the synovium. 2 The knee is the most affected joint. 3,4,7 It might present bilaterally but monoarticular involvement is more common.…”

“…1 The term "arborescens" means "tree-like appearance" describing the villous morphology. 2 It has been considered to be a reactive process of the synovial tissue; however, the etiology is still unclear. 3 It usually presents as a painless and slowly progressive swelling in joint which is commonly monoarticular; however, bilateral and polyarticular involvement were also reported.…”

“…3 It usually presents as a painless and slowly progressive swelling in joint which is commonly monoarticular; however, bilateral and polyarticular involvement were also reported. [1][2][3][4][5] Laboratory test results are usually normal, but mildly elevated erythrocyte sedimentation rate (ESR) and slightly increased C-reactive protein (CRP) levels may be seen. 5 Magnetic resonance imaging (MRI) and synovial biopsy have importance for precise diagnosis.…”
