Periosteal chondroma of the fifth toe--a case report.
A case of a periosteal chondroma arising in the fifth toe is reported. A 19-year-old man presented a palpable mass of his left fifth toe with pain for 2 years. Plain radiographs showed mild irregularity of the cortical bone of the fifth proximal phalanx. Magnetic resonance imaging revealed a tumour attached to the fifth proximal phalanx with low signal intensity on T1-weighted images and high signal intensity on T2-weighted images without intramedullary extension. The tumour was enhanced heterogeneously after intravenous injection of gadolinium diethylene triamine penta-acetic (GD-DTPA). The tumour was removed, together with the covering periosteum. It was diagnosed as periosteal chondroma histologically.
