title: [Clinicopathologic analysis and genetic investigation of two families with cherubism].
abstract: OBJECTIVE
  To study genetic feature, clinical and histopathological characteristic of two Chinese kindreds with cherubism (CBM).
  
  
  METHODS
  Two Chinese kindreds with CBM were investigated. The affected individuals of two families were analyzed with medical history, clinical manifestations, classified grading system, radiographic assessment, histopathological findings, and hereditary nature.
  
  
  RESULTS
  There were 2 individuals affected with CBM in family A and 3 patients involving three generations in family B. Two probands were diagnosed aggressive form cherubism and classified as grade IV. In histopathological findings, besides varying numbers of multinucleated giant cells in a stroma of fibroblasts and the eosinophilic cuffing surrounding some vessels, actively proliferating areas with clear mitoschisis and relative dormant areas with loose fibrous tissue and bone were also presented in microscopic fields of the lesion.
  
  
  CONCLUSIONS
  Cherubism is caused by autosomal dominant inheritance. The diagnosis should be based on the genetic, clinical, radiological, and pathological aspects of the disease.
