“…All patients had single lesion; one has a bilateral presentation [ 26 ]. Eleven lesions (50%) were located in the shoulder [ 1 – 3 , 22 , 24 , 28 , 30 , 32 , 33 , 35 , 36 ], seven (31.82%) in the elbow [ 13 , 23 , 25 , 26 , 29 , 34 ], and four (18.18%) in the wrist [ 14 , 27 , 31 , 37 ]. All patients but one had preoperative MRI scans during the diagnostic assessment [ 27 ].…”

“…Clinical manifestations of LA are nonspecific and frequently resemble osteoarthritis, inflammatory arthritis, or infection [ 4 , 6 ]. Monoarticular swelling or pain of insidious onset, intermittent joint effusion episodes or a slowly growing subcutaneous mass are common in patients with LA [ 1 , 7 ]. Magnetic resonance imaging (MRI), using fat suppression or short tau inversion recovery (STIR) sequences point to the diagnosis in most patients with LA [ 8 ].…”

“…Magnetic resonance imaging (MRI), using fat suppression or short tau inversion recovery (STIR) sequences point to the diagnosis in most patients with LA [ 8 ]. Although its etiology remains unknown [ 1 ], it has been hypothesized that LA may result from reactive differentiation of synovial cells towards adipocytes [ 9 ]. Two aetiological types have been described.…”

“…The secondary type is more common in the elderlies, and is associated with pathological conditions or lesions causing chronic irritation [ 7 , 12 ]. The knee is the most frequent location of LA [ 1 – 3 ]; however, lesions of the wrist, elbow, shoulder, ankle, and hip joints have been reported [ 2 , 10 , 13 – 16 ]. For LA in the knee, arthroscopic synovectomy demonstrated excellent short-term results and a low rate of recurrence [ 15 ].…”

Surgical management of upper limb lipoma arborescens: a systematic review

Background Lipoma arborescens (LA) is a rare benign synovial tumour characterized by the proliferation of mature adipocytes within the synovial cells. Given its rarity, current evidence is mainly based on case reports and case series, and no guidelines are available. The present study investigated the current surgical management and related outcomes of LA in the upper limb. Methods This systematic review was conducted following the PRISMA guidelines. PubMed, Scopus, and Virtual Health Library were accessed in September 2021. Clinical studies evaluating patients with LA undergoing surgical treatment were considered eligible for this systematic review. Only studies which reported data on LA located in the upper limb with histopathological confirmation were considered. Articles that reported data from nonsurgical management were not considered. Results A total of 21 studies reporting 22 lesions in 21 patients were assessed. The mean age of the patients was 48.48 years (range 22–77). Most studies evaluated the restoration of range of motion and symptom resolution for the functional outcome assessment. Open or arthroscopic excision and synovectomy were the most common surgical procedures for LA. The concomitant lesions were treated in a single-stage procedure. All patients had satisfactory outcomes after open or arthroscopic excision and synovectomy without recurrence at a mean follow-up of 21.14 months (range 2–60). One patient developed postoperative cellulitis (4.55%). Conclusion Open and arthroscopic excision combined with synovectomy should be considered the standard treatment option of upper limb LA. Concomitant pathologies can be addressed in a one-stage procedure. Although LA was recognized as a clinical entity decades ago, there is a lack of evidence based guidelines and long term outcome data are unavailable.
