title: [Primary oral peripheral chondrosarcoma. Anatomo-clinical aspects and presentation of 2 cases with periodontal onset].
abstract: After a brief analysis of the anatomoclinical aspects of chondrosarcoma in general and of the characteristic and particular aspects of the forms with maxillofacial onset (lower age of onset, elective sites of onset anterior in the maxillary and posterior in the mandible, often insignificant standard X-ray pictures, high percentage of error in clinical and histological diagnosis) two cases of peripheral periodontal onset, with low degree of malignity (grade 1), with aspecific clinical and radiological aspects, both locally recurrent several times after nonradical surgery are reported.
