Solitary endobronchial glandular papilloma: a report of two rare cases.

Glandular papillomas are the rarest type of solitary endobronchial papillomas of the lung, which are in themselves extremely uncommon, and are mainly described in the literature as case reports. These tumours generally arise from the epithelium of central lobar or segmental bronchi and are thought to be benign, with only a single documented case of malignant transformation to date. Diagnosis may be challenging, and there is no consensus on treatment; however, surgical resection with a parenchymal-sparing approach is an accepted treatment option. In this report, we present two cases of solitary endobronchial glandular papilloma in young females who underwent surgical resection. In one case, we also describe an associated diagnosis of a concurrent pulmonary adenocarcinoma. We aim to contribute to the growing body of literature on these rare neoplasms and highlight the importance of a considered approach to their treatment.
