Simultaneous occurrence of facial fibrous dysplasia and ameloblastoma.

BACKGROUND

Both fibrous dysplasia (FD) and ameloblastoma are benign but locally aggressive tumours of the craniofacial region. In this case report, we present the unique synchronous occurrence of these two tumours in the facial skeleton.

CASE REPORT: A 16-year-old woman presented with complaints of swelling of the upper right face and at the inferior border of the mandible. She was diagnosed as FD of the maxilla, temporal bone and sphenoid sinus together with ameloblastoma of the mandible after surgery and histopathological evaluation.

CONCLUSION

The case that we present here is unique in that two separate pathological conditions, FD of the upper face, and ameloblastoma of the mandible coexisted. Although cases of synchronous or metachronous occurrence of FD and ameloblastoma with other pathology have been previously described, this to our knowledge, is the first reported case of true coexistence of FD and ameloblastoma.
