Abstract

Jonathan Danaraj, Andras Khoor and Isabel Mira-Avendano

Mixed squamous and glandular papilloma of the lung is uncommon. Current literature demonstrates that there are less than 20 cases documented worldwide, though likely underreported. We present a case of a 58 y.o. female with history of COPD who was found to have mixed squamous and glandular papilloma, confirmed by histology. This case highlights an unusual etiology of endobronchial lesion that can mimic a malignancy. Clinicians should be aware of this entity because resection can be curative and prognosis is good.
