Adamantinoma - Diagnosis, Surgical Management and Prognosis

Primary Bone Tumors

A 32-year-old man presents with a slowly enlarging, painless mass on the anterior aspect of his right leg that he first noticed 2 years ago.

Radiographs show an eccentric, intracortical lytic lesion in the anterior tibial cortex with a "soap-bubble" appearance and surrounding sclerosis.

The tumour board discusses the diagnosis and recommends wide resection. Regarding adamantinoma of bone:
