Adamantinoma of the long bones. The experience at the Istituto Ortopedico Rizzoli

Abstract

All cases of adamantinoma seen at the Istituto Ortopedico Rizzoli were retrospectively reviewed. Although this tumor is exceedingly rare, nine cases were collected. The tumor is composed of four histological patterns: spindle, basaloid, squamoid, and tubular. The prognosis of this tumor depends on the adequacy of therapy. Surgery that is expedient and adequate tends to offer the best prognosis.
