title: Solitary bone cyst of the radius containing Liesegang's rings.
abstract: The authors describe the case of a 33-year-old man with a solitary cystic lesion of the left distal radius with central radiodensities that radiographically suggested a chondroid matrix. Curettage of the lesion revealed numerous calcospherites with a lamellar structure. This lamellar pattern is thought to be a result of alternating precipitation and diffusion of supersaturated solutions. This biochemical process has been called the Liesegang's phenomenon, and the structures have been termed Liesegang's rings. The presence of these structures in this benign lesion contributed to atypical roentgenographic and pathologic findings.
