Lipoma arborescens in a 16‐year‐old male: A case report

Abstract

Lipoma arborescens is a benign intra‐articular tumor characterized by joint effusions, pain, and reduced range of motion. It is rare in adults and children. We present a case of lipoma arborescens in a 16‐year‐old male. The work up involved plain radiographs, MRI, incisional biopsy, and laboratory analysis.

Successful use of adalimumab as a conservative treatment for bilateral knee lipoma arborescens in patient with psoriatic juvenile idiopathic arthritis – case report and review of literature

“…Although the etiology and pathogenesis of LA has not yet been well defined, according to most authors, it is primarily related to chronic synovial irritation, particularly in cases of osteoarthritis or previous trauma as the triggering factors ( 1 – 7 , 15 ). During the last decade a growing number of reports advert the inflammatory diseases, such as rheumatoid arthritis, psoriatic arthritis or psoriasis, autoimmune uveitis and different types of JIA, as possible underlying conditions related to the development of LA ( 2 , 4 – 6 , 10 , 14 , 15 ).…”

“…The incidence of LA among children and adolescents, particularly with inflammatory diseases, is extremely low ( 10 , 11 ). A couple of dozen childhood cases have been reported to date; however, all authors have described only one or two patients for each study ( 7 – 18 ). Among these, there are only a few explicit cases of commonly unsuccessful conservative therapy of LA in children with JIA ( 11 – 16 ) ( Table 1 ).…”

“…Despite its obscure etiology, it is considered a nonspecific reactive response to chronic synovial irritation ( 1 – 6 , 8 , 10 , 15 ). LA is usually unilateral, with the suprapatellar pouch of the knee as the most common site of involvement ( 1 – 7 , 9 – 11 ). It may also affect other joints, as well as extra-articular sites such as periarticular bursae and tendon sheaths ( 1 , 2 , 4 – 6 , 9 , 10 ).…”
