ARTICLE HIGHLIGHTS
Research background
Metastatic adenocarcinoma of the jaw (MAJ) is a rare disease that accounts for 1%-3% of all oral and maxillofacial malignant tumours. To date, few studies have focused on the diversity of imaging features, and no study has classified the computed tomography (CT) findings of MAJ.
Research motivation
Oral and maxillofacial pain may be the first symptom of metastatic spread of an occult primary tumour. Therefore, early identification of oral and maxillofacial pain by dental professionals is important.
Research objectives
To explore the clinical and CT features of MAJ with oral and maxillofacial pain as the first symptom.
Research methods
Fourteen cases of MAJ from 2006 to 2020 in our hospital were collected, and clinical and the CT features were analysed retrospectively.
Research results
MAJ occurs predominantly in middle-aged and elderly men, with the most common site being the posterior mandible. MAJ is marked by numb chin syndrome (NCS), as well as rapidly progressive osteolytic bone destruction with periosteal reaction and a localised soft tissue mass, usually without jaw expansion on CT.
Research conclusions
MAJ has complex clinical and CT features. Oral and maxillofacial pain may be the first sign of a primary tumour affecting other sites. When middle-aged and elderly patients present with NCS, and CT images reveal rapidly progressive osteolytic bone destruction with moth-eaten and permeative margins, clinicians should be aware of the possibility of MAJ and attempt to identify the primary lesion early to improve survival.
Research perspectives
Further studies with larger sample sizes are required to confirm our results.
