Popis:	In solitary bone cysts (SBC), the level of intra-cystic alkaline phosphatase (ALP) has been reported to be obviously high compared with that of serum in the past, however, only a few reports on its origin and effectiveness are available. We report the results of a comparative study of the roentgenographic appearance and levels of serum/intra-cystic ALP in 12 patients operated for primary SBC. All patients were classified into the Non-sclerotic (NS) group (7 cases) and Sclerotic (S) group (5 cases) based on the marginal sclerosis and clear definition on plain roentgenograms. In the NS group, the level of the intra-cystic ALP was extremely high compared with that of serum, and also with intra-cystic ALP in S group. Histologically, osteoid formation with numerous osteoblasts rimmings and marked calcification on the osteoid and amorphas fibrin were recognized, and this is suggested to bo the origin of the elevation of the intra-cystic ALP in SBC.
