“…A systematic review on the arthroscopic treatment of LA of the knee revealed a satisfactory short-term outcome [ 15 ]. The present study supports similar findings: patients may benefit from less invasive arthroscopic procedures when feasible, as arthroscopic treatment of shoulder [ 2 , 3 , 28 , 35 , 36 ] and elbow lesions [ 13 ] led to promising short-term outcomes. Although LA was recognized as a clinical entity decades ago, the evidence is scarce and long term outcome data are unavailable.…”

“…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 ].…”

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.

Introduction:Lipoma arborescens is a tumor-like lesion that occurs inside joints and synovial bursae, especially in knee joints. It rarely occurs in the shoulder joints and this disease usually causes severe shoulder pain. This study aims to report a rare case of lipoma arborescens occurring in the subdeltoid bursa with severe shoulder pain. Case Report: A 59-year-old woman with severe pain and restriction of range of motion (ROM) for her right shoulder consisting for 2 months was referred to our hospital. Magnetic resonance imaging (MRI) findings revealed that a tumor-like lesion exists in the subdeltoid bursa in her right shoulder and blood examinations revealed no abnormal findings. Surgical resection of the tumor-like lesion was performed and the rotator cuff was repaired because this tumor-like lesion invaded the rotator cuff partially. Pathology examination of the resected tissues was consistent with lipoma arborescens. One year after surgery, the patient’s shoulder pain was diminished and its ROM recovered. There was no significant difficulty in activities of daily living. Conclusion: Lipoma arborescens should be considered when patients present with complaints of severe shoulder pain. Even if their physical findings do not suggest rotator cuff injuries, MRI should be performed to rule out lipoma arborescens. Keywords: Lipoma arborescens, shoulder, subdeltoid bursa.
