Abstract
Ameloblastoma is the most common odontogenic tumor, but the incidence of its metastasis is low. We report a case of recurrent ameloblastoma metastasizing to the cervical lymph node. This patient presented with a radiolucent cystic lesion in the left mandibular region. Segmental mandibulectomy along with cervical lymph node dissection was performed. Histopathological features revealed an ameloblastoma with single lymph node metastasis. The patient had two previous instances of lesion at same site which were diagnosed to be ameloblastoma on histopathology. Metastasizing ameloblatomas are different from ameloblastic carcinomas and lymph node metastasis is especially rare. The case is presented as it exhibits this peculiar feature.References
