RESUMO
Ameloblastic carcinoma is an uncommon malignant odontogenic tumor of jaws and is a highly aggressive tumor with rapid growth and also a high potential for distant metastasis. Th e most common site of occurrence is posterior mandible. Clinically, it is aggressive and has potential for local destruction. Th e majority of the cases arise de novo, while few cases arise from a pre-existing ameloblastoma. Th e radiological feature of the ameloblastic carcinoma is usually similar to that of ameloblastoma except for the presence of focal radiopacity, which apparently refl ects dystrophic calcifi cation. Herein, we report a case of ameloblastic carcinoma in the left mandible of a 60-year-old female patient.
RESUMO
Odontogenic keratocyst was the first illustrated by Phillipsen in 1956 and is unique as it is aggressive locally, and rate of recurrence is high along with histological appearance which is very characteristic. It is a benign neoplasm of jaw with the diverse origin and its occurrence in maxilla is uncommon. We present a case of 30-year-old male with aggressive keratocystic odontogenic tumor (KCOT) in the right maxillary molar region. On radiological examination, radiolucent area, mimicking radicular cyst, was found in relation with maxillary first molar. A final diagnosis of KCOT was confirmed after histopathological findings. The clinical, radiological, and histopathological features of this tumor along with surgical management have been discussed.
