NEONATAL OSTEOFIBROUS DYSPLASIA - REPORT OF 2 CASES

Skeletal neoplasms of the newborn and neonatal period are infrequently encountered and often misdiagnosed. Osteofibrous dysplasia is a tumor of childhood that may be seen in the newborn. Because of its unique n atural history, with and without surgical treatment, and the similarit y in radiographic appearance of this tumor to other lesions, a high in dex of suspicion must be maintained when a tibial lesion is encountere d in the newborn. We present two additional cases of neonatal osteofib rous dysplasia and discuss the differential diagnostic considerations.
