Presented here is a rare occurrence of ameloblastic carcinoma located in the maxilla of a pediatric patient. The patient's chief complaint is a large mass protruding from the right maxillary area diagnosed as ameloblastic carcinoma before consulting the nuclear medicine section for whole-body bone scintigraphy. Whole-body bone scintigraphy was performed with cranial SPECT imaging. The maxillary tumor appeared to have decreased radiotracer uptake with intense activity in the anterior and anteromedial aspects of the tumor. There was also a focus of uptake in the lateral border of the tumor, radiating to the angle of the right mandible. Mandibular X-ray series was also acquired, with findings that correlate with those of the bone scintigraphy.
