Role of positron emission tomography in primary carcinoma ex pleomorphic adenoma of the bronchus: A case report.

BACKGROUND

Primary carcinoma ex pleomorphic adenoma arising from the tracheobronchial system is rarely reported.

CASE SUMMARY: We present a patient with primary carcinoma ex pleomorphic adenoma of the bronchus and review the associated literature for further comparison, including age, clinical manifestations, and diagnostic process. This patient had no history of neoplasms of the salivary gland.

CONCLUSION

Positron emission tomography played an important role in the staging work-up of primary carcinoma of ex pleomorphic adenoma. Long-term follow-up was necessary for further prognosis analysis.
