A Rare Case of Ameloblastic Carcinoma

Abstract

Ameloblastic carcinoma is a rare type of ameloblastoma that has received little mention in the literature. While a number of cases have been published over many years, no institution has been able to produce a substantial case series. Ameloblastic carcinoma originates in the embryonic tooth components. It is believed to be an aggressive tumor that can metastasize; once metastasis occurs, the prognosis tends to be poor. Ameloblastic carcinoma is primarily a surgical condition that is best treated with resection; there has been little indication that other modalities are helpful. We present the case of a 40-year-old woman who was found to have a mandibular lesion by a dentist. After surgical resection, the tumor was found to be an ameloblastic carcinoma. The patient recovered without complication, and she was recurrence-free 18 months postoperatively. We also briefly review the available literature on the natural history of and management options for this rare tumor.

Ameloblastic carcinoma of the mandible: a case report

“…Furthermore, the diagnosis rate of preoperative AC is reported, invasion as low as 39%, and preoperative diagnosis is considered difficult [14]. In the past 10 years, 13 (61.9%) of 21 cases of AC in the area of the bone of the jaw were diagnosed as benign tumors (Table 1) [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. On the other hand, 7 cases (33.3%) led to a diagnosis of a malignant tumor.…”
