Bronchogenic adenocarcinoma metastatic tumour mimicking a dentoalveolar abscess in maxilla

Intra-osseous metastatic tumours (IOM) in maxilla are less frequent than the soft tissue metastatic tumours. Lung and bronchogenic metastatic tumours are uncommon in the maxilla. We present a maxillary bronchogenic metastasis with a rare clinical appearance. IOM was misdiagnosed as a dentoalveolar abscess and treated with antibiotics for three weeks. After not responding to antibiotics, the patient's doctor of dental medicine (DMD) forwarded the patient to the Department of Oral and Maxillofacial Surgery. The associated tooth was extracted and the patient was summoned a week later. There were no signs of improvement observed and thereby cytology, biopsy and radiology diagnostics were performed. Cytological results and biopsy could not differentiate a metastatic tumour from a salivary duct carcinoma. Ultimately, negative androgen receptors immunohistochemistry spoke in favour of bronchogenic metastatic adenocarcinoma. This case report stresses the importance of taking a thorough medical history. To our knowledge, this is the third bronchogenic IOM to the maxilla reported, mimicking a dentoalveolar abscess. DMDs are placed to be among the first in contact with oral metastatic tumours and it is thereby important to report unusual clinical cases, as they present a diagnostic challenge for both the clinician and the pathologist.
