A Juxta-Articular Myxoma of the Thumb

Abstract

Benign hand tumors Myxoma Juxta-articular myxoma Soft tissue tumors Juxta-articular myxomata are benign tumors that are mostly encountered in the vicinity of larger joints. Few cases in the hand have been reported. We present a case of a juxta-articular myxoma at the metacarpophalangeal joint of the thumb in a 40-year-old man. The preoperative diagnostic work-up included 4-dimensional magnetic resonance angiography and ultrasound. The histochemical examination of the resected tumor established the diagnosis definitively. Follow-up magnetic resonance imaging scheduled with no clinical suspicion of tumor recurrence 9 months after surgery revealed no obvious recurrence. At 14 months, the patient had full motion without pain and declined further imaging.

The Viscous Juncture-Juxta Articular Myxoma

“…Disease Characteristics Juxta-articular myxoma is commonly associated with large joints such as the knee which is incriminated in a majority (88%) of instances. Additionally, elbow, shoulder, ankle, wrist, hip or joints of the hand may be implicated [2,3]. Tumour magnitude generally varies from 0.6 centimetres to 12 centimetres although a majority of neoplasms are beneath <5 centimetres.…”

“…Tumour magnitude generally varies from 0.6 centimetres to 12 centimetres although a majority of neoplasms are beneath <5 centimetres. The neoplasm is frequently associated with conditions such as meniscal tear and osteoarthritis (2,3). Disease emergence usually occurs within the third to fifth decades.…”

“…Children are exceptionally incriminated wherein the neoplasm is usually discerned within the knee joint or wrist. A male predominance is observed with a male to the female proportion of nearly 3:1 [2,3]. Although the tumefaction is non-destructive or locally destructive, an estimated one third (34%) of neoplasms are associated with localized tumour reoccurrence.…”

“…Although the tumefaction is non-destructive or locally destructive, an estimated one third (34%) of neoplasms are associated with localized tumour reoccurrence. Of controversial genesis, juxta-articular myxoma may be engendered as a posttraumatic consequence or an arthritic disease [2,3]. Clinical Elucidation Pain can occur in the absence of clinically evident neoplasm although tumefaction can arise in the absence of pain.…”

“…Clinical Elucidation Pain can occur in the absence of clinically evident neoplasm although tumefaction can arise in the absence of pain. On account of localized tissue destruction associated with the neoplasm, pain or nerve palsy can manifest [2,3]. The occurrence of a painful lesion requires differentiation from localized or referred hip pain arising due to concomitant disorders of knee or foot.…”
