Abstract
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.

Keywords: Primary carcinoma ex pleomorphic adenoma, Positron emission tomography, Bronchus, Lung, Metabolically active region, Case report

Core Tip: Positron emission tomography plays an important role in defining the size of the malignant component of primary carcinoma ex pleomorphic adenoma and affects its clinical staging.
