Intraosseous ganglia occur most frequently in the long bones of the lower limbs, particularly in the medial malleolus of the tibia. They usually appear as radiographically well circumscribed juxta-articular cystic lesions, containing myxoid fibrous tissue histologically. Intraosseous ganglia in the hand are very rare. Most reported cases have involved the carpal bones, in particular the lunate and scaphoid. To our knowledge, the present case is the third report of an intraosseous ganglion appearing in the first metacarpal bone; it arose in a patient who had been on dialysis for 25 years, mimicking amyloidosis of bone.
