Mandibular Metastasis of a Recurrent Poorly Differentiated Urothelial Bladder Carcinoma

What is it about?

Metastatic lesions to the oral cavity are uncommon; they represent between 1 and 3% of all malignant oral neoplasms. In this article, we report a rare case of metastatic urothelial bladder carcinoma in the mandible detected on oral radiographic images and confirmed with multiple imaging modalities. A 67-year-old woman presented to our clinic suffering from pain in the right side of the mandible with a mild swelling. Panoramic radiograph revealed an ill-defined relatively radiolucent lesion in the right mandibular premolar-canine region presenting with permeative changes. Cone-beam computed tomography showed a relatively hypodense lesion with demineralization, interruption of the buccal cortices, and slight thickening and sclerosis of the buccal cortical bone. e patient was referred for further evaluation including additional advanced imaging radiographic techniques (MRI and PET scan) and clinical and histopathological examinations that lead to a final diagnosis of metastatic lesion from an underlying urothelial bladder carcinoma.
