Abstract
Papilloma of the lung is a rare benign entity and can be solitary or multiple. Solitary papilloma is subclassified into three categories: squamous papilloma, glandular papilloma, and mixed squamous and glandular papilloma. Glandular papilloma is the rarest subtype among them and occurs mostly in the sixth decade without any relation to smoking, syndrome, or infection. Histology is characterized by mixture of pseudostratified, columnar, nonciliated, mucinous epithelium-lined papillary fronds without any mitoses, necrosis, or atypia. The differential diagnosis can be broad depending upon the histologic features present in a particular case and may include both benign and malignant entities. We present here a patient with glandular endobronchial papilloma showing unusual clinical history and atypical histologic features, which required extensive immunohistochemical evaluation to establish a final diagnosis.
