CGCG is a rare lesion, behaving in a way which is often unpredictable, varying from a slowly swelling to a highly aggressive, painful lesion. Opinions differ on whether it is neoplastic or reactive. This study was a retrospective examination of 26 patients with CGCG seen in a German hospital over a 24 year period. The lesions were classified as non-aggressive (NA; mean age and range: 8.6 yrs, 4.8-14.0) or aggressive (A; 15.3, 6.0-57.4), and their characteristics compared.

Females accounted for 2/3 of all cases, and 2/3 also were in the mandible. Group A lesions appeared much larger at diagnosis (mean diameter 56 v. 33 mm). In group A, pain, rapid growth, root resorption and displacement were common; in group NA, these features did not occur. There were no recurrences in group NA, but 4 in group A. Surgical removal was undertaken in all cases: curettage in 5 cases, curettage with ostectomy in 20, and extra-oral block resection in one. The authors consider that the clinical and histological features may help predict the behaviour of the lesions.
