Adamantinoma

Adamantinoma is a rare bone cancer, making up less than 1% of all bone cancers. It predominantly arises in bone in a subcutaneous location (85% are in the tibia). Most commonly, patients are in their second or third decade, but it can occur over a wide age range.

Treatment

Treatment consists of wide resection or amputation. Metastases are rare at presentation but may occur in up to 30% of patients during the disease course. Prognosis is excellent, with overall survival of 85% at 10 years, but is lower when wide surgical margins cannot be obtained.
