Solitary bone cysts in children

Abstract

Solitary bone cyst (SBC) is one of the most common childhood pathologies of the skeleton. According to different authors, SBC represents 21 % to 57 % of the benign tumors and tumor processes in the bones of children. SBC usually consists of a single chamber cavitary formation filled with a transparent liquid with a straw colored lining of varying thickness, which consists of connective tissue and single giant cells. There is no consensus on the etiopathogenesis of SBC, and the choice of treatment. There are no clear indications for conservative and surgical treatment of SBC. Some authors are inclined to use puncture (minimally invasive) treatments, while others choose more radical surgical methods. Both methods have the same relapse rate at up to 27 %. In this article, we analyzed the published data on the etiology, pathogenesis, diagnosis, and methods of treatment of SBCs in children.
