Ameloblastic carcinoma of the maxilla: A case report

Abstract. This study aims to present the clinical features and treatment of a case of maxillary ameloblastic carcinoma. Ameloblastic carcinoma is a rare malignant odontogenic carcinoma that has metastatic potential. Due to its rare incidence, there are few studies focusing on its radiological characteristics. When ameloblastic carcinoma demonstrates an aggressive appearance, it may be diagnosed as a malignant tumor; however, in cases showing a non-aggressive appearance, it is difficult to distinguish ameloblastic carcinoma from ameloblastoma. We report a case of ameloblastic carcinoma of the maxilla in a 59-year-old male patient, including the clinical signs, radiological images and pathological features. A partial area was surgically excised under local anesthesia and the material was sent to the Laboratory of Oral Pathology. The histological sections revealed a fragmented odontogenic tumor of epithelial origin, consisting of solid parenchyma and also revealed basal cells resembling ameloblasts, occasionally arranged in palisades. Certain parts of the architecture resembled that of an ameloblastoma; however, the cytology of other areas confirmed the diagnosis of ameloblastic carcinoma of the maxilla. The patient was scheduled for definitive surgery, including a right maxillectomy and radiotherapy. The patient was followed up every 3 months. After 2 years follow-up, there were no clinical or radiological signs of recurrence.

“…2 Ameloblastic carcinoma is a term given to tumours that display histologically malignant features in both primary and metastatic sites with a pattern otherwise resembling ameloblastoma. 2 A review of the literature from 1927 to 2006 revealed 66 cases of ameloblastic carcinoma: 20 cases reported metastases, the majority to the lung; 3 with only 1 case of ameloblastic carcinoma arising from the anterior skull base; 4 1 case of direct extension to the skull base; and 2 case reports, on the same patient, of metastasis to the skull. 5 Review of the literature reveals there is very little written regarding the MRI and 18-fluorodeoxyglucose positron emission tomography-CT (PET-CT) features of ameloblastic carcinoma.…”

Ameloblastic carcinoma is a very rare malignant odontogenic tumour with characteristic histopathological and clinical features, which requires aggressive surgical treatment and surveillance and, therefore, differs from ameloblastoma. Metastasis typically occurs in the lung. Only one patient with metastasis to the skull has previously been described and no prior case reports have presented MRI and positron emission tomography-CT (PET-CT) imaging findings. We describe a case of ameloblastic carcinoma with metastasis to the skull and lung with emphasis on imaging features including MRI and PET-CT.
