Résumé :	Unicameral bone cysts (UBC) and aneurysmal bone cysts (ABC) are benign cystic lesions of bone which are easily diagnosed. However, unusual locations may lead to a false diagnosis. Therefore the aim of this retrospective study was to determine the frequency of unusual localizations. The authors studied 451 cases with histopathologically confirmed diagnosis of UBC or ABC, seen between 1981 and 2012. In the UBC group (352 cases) humerus, femur and calcaneus were found to be the most common sites, while acetabulum, scapula, scaphoid, lunatum, metacarpals, metatarsals, toe phalanges and ulna each accounted for less than 1%. In the ABC group (99 cases) the most common sites of involvement were femur, humerus and tibia, while finger phalanges, ilium, acetabulum, pubis, calcaneus, cuboid, and toe phalanges each accounted for only 1%. The differential diagnosis of cystic bone lesions should include both UBC and ABC. Pain complaints plead for the latter, except in case of fracture.
