Traumatic bone cyst, aneurysmal bone cyst, and central giant cell granuloma--pathogenetically related lesions?

Three central bone lesions, a traumatic bone cyst, an aneurysmal bone cyst, and a central giant cell granuloma are reported. Comparisons of the clinical, radiographic, and histological features were made. Although these lesions are recognized as separate and distinct pathological entities, a common pathogenesis is suggested by similarities in certain features. Diagnostic aids are suggested to assist in a differential diagnosis.
