Abstract
Three cases of multiple enchondromatosis including an Ollier's disease were reviewed in this report. Clinical featurees of multiple enchondromatosis were variable and subclassifications were thought to be necessary.
Case 1: a 59-year-old man with his onset of tumor formation of both hands at 23 years old. Deformity or shortening of long bones were not seen. The pathohistological examination revealed no malignancy.
It was subclassified as a neoplastic type in multiple enchondromatosis.
Case 2: a 11-year-old girl with her onset at 8 years old. The tumors were localized in the right fingers and both toes. Clinical features showed both neoplasma and developmental anomaly, and is was subclassified as an intermediate type.
Case 3: a 8-year-old boy wiht his onset of limping due to limb discrepancy at 5 years old. Roentgenographically the tibia showed shortening deformity and cartilage nests which were charactaristic in Ollier's disease. It was caused by failure of normal enchondral ossification and subclassified as a developmental anomaly.
