Abstract
This case report describes a juxta-articular myxoma(JAM) in an uncommon location, demonstrating an unusually aggressive local growth pattern.
Highlights
Myxomas are benign mesenchymal tumours characterised by the production of mucinous material in a scant spindle cell matrix.[1]
Juxta-articular myxoma (JAM) is most commonly associated with large joints, with a male preponderance
Postoperative recurrence is seen in approximately 30% of JAMs within five years of excision.[3,4]
Summary
Myxomas are benign mesenchymal tumours characterised by the production of mucinous material in a scant spindle cell matrix.[1] Juxta-articular myxoma (JAM) is a rare form of myxoma in the vicinity of a joint.[2] JAM has an association with trauma or joint arthrosis. It is may be locally aggressive and commonly recurs after surgical excision.[3]. The MRI showed recurrence of the thenar eminence JAM, marked progression of the erosive intraosseous components, prominent flexor and extensor tenosynovitis, and radiocarpal and intercarpal synovitis (Figure 8)
