title: Aneurysmal bone cyst of the hand.
abstract: Diagnosis of aneurysmal bone cyst in the hands is confused by rarity (2%) and overlapping characteristics of other lesions, especially benign osteoblastoma and giant-cell tumor. Pseudosinusoidal vascular channels create interfaces between liquid blood (maintained by fibrolysin) and connective tissue cells. The role of trauma is inexplicable.
