Background - Desmoplastic ameloblastoma is a rare benign
odontogenic tumour with an aggressive growth potential and
a high recurrence rate. The tumour occurs mainly in middleaged
patients as a painless hard and slowly growing swelling
in the incisor and premolar region. Radiographically, a diffuse
ill-defined mixed radiolucent and radiopaque lesion is seen.
The tumour has an infiltrating growth pattern in the cancellous
bone for which reason radiographical demarcation is difficult.
Desmoplastic ameloblastoma is treated with surgical
resection. Because of the high recurrence rate, prolonged
clinical and radiological control regime is necessary.
Case study - A 63-year-old female was referred from her
dentist to the Department of Oral and Maxillofacial Surgery,
Aalborg University Hospital, for diagnosis and treatment of
a hard painless and slowly growing swelling in the anterior
region of the mandible. Radiographic examination revealed
a diffuse ill-defined mixed radiolucent and radiopaque lesion
from the region of mandibular right canine to the left
lateral incisor. Histological examination of a biopsy revealed
changes compatible with desmoplastic ameloblastoma. The
tumour including the associated teeth was resected.
Conclusion - Desmoplastic ameloblastoma is a rarely occurring
odontogenic tumour which has many comparable clinically
and radiologically characteristics of other pathological
jaw lesion Histological examination and diagnosis is necessary
in order to choose the appropriate treatment.
