A rare neoplasm of bone which shows great resemblance to that referred to in the literature as chondromyxoid fibroma is described. Two new cases are reported and three similar ones previously published are mentioned in brief.
The characteristics of the neoplasms that differentiate them from chondromyxoid fibromata are: onset in childhood, pronounced symptomatology, rather rapid course, predominance of myxoid tissue, metachromasia in the ground substance, and invariable recurrence after simple curettage. In view of these traits it is proposed that this tumor be called myxoma of bone. Surgeons are advised to treat these tumors by radical local resection.
