ADAMANTINOMA OF THE OLECRANON - A REPORT OF A CASE WITH SERIAL METASTASIZING LESIONS

Adamantinomas are slow-growing, invasive malignant tumors. Although th e majority of cases have arisen in the tibia, these aggressive tumors have been reported in most of the long bones. This is the first known report of a patient with adamantinoma of the olecranon, an unusual sit e for this lesion. However, the patient not only had a novel site of a ppearance of the tumor and local recurrence of the disease, but also h ad a series of distant, isolated, bony tissue metastases before a fata l metastasis to the lung within a 9-year period. Although metastasis t o other bony sites has been reported, a series of metastases to bony a nd soft tissues is unusual.
