about that its origin be traumatic, malformation of neoplasm. The radiographic appearance may to show from a diffuse image up to a well defined image very
similar to the other maxillary lesions turning wide the differential diagnosis. With
destruction of the bon cortex it is possible to create a reaction image of periosteum
in sunbeams characteristic of malignant lesion. This is the case of a female patient
aged 17 seeking help in the Bucco-maxillofacial Surgery and Traumatology Service
of the São Vicente de Paulo Hospital RS, presenting with pain and an increased
mandibular volume. She manifested that around one year she began to feel a
discomfort next to he right mandibular angle, which was progressively increasing
the volume. The radiographic appearance resembled a malignant lesion. After the
histopathology verification of ABC, treatment choosed for this case was of type
conservative surgical with bone cavity curettage and was maintained under
systemic postoperative control for 6 and 18 months. In the taken panoramic
radiographies is verified the bone neoformation and the cure of case.
