The glandular papilloma, as seen in our patient, represents a very rare subtype of pulmonary papillomas.3 We performed a MEDLINE search, restricted to the English language from 1954 to the present, and found only 13 case reports of pulmonary glandular papillomas.3,7–12 The mean age (± SD) of patients was 60 ± 13 years, with eight pulmonary glandular papillomas found in men, and five in women. Eleven of the 13 patients (84.6%) presented with endobronchial disease and had associated clinical symptoms, such as hemoptysis, wheezing, and recurrent pneumonia. Only one patient (7.7%) presented with an incidental peripheral pulmonary nodule. The patient in the remaining case had no information on the location of the lesion. As opposed to the squamous and mixed papillomas, the glandular papilloma tends to occur in nonsmokers and in an older patient population.3 Basheda and colleagues11 initially reported a right-sided predominance for glandular papillomas as demonstrated in our case, but a later study by Flieder and colleagues3 could not confirm this observation. Our review revealed five cases of left-sided lesions and eight cases of right-sided lesions, including our case. Seven of the eight right-sided solitary glandular papillomas were found in the lower lobe. Little is known about the growth rate of papillomas. The calculated doubling time for our patient’s tumor was 220 days, a growth rate that is commonly observed for malignant disease (50 to 500 days). As opposed to the stated literature on squamous papillomas, there have been no reports of the malignant transformation of glandular papillomas, although the number of reported cases remains limited. Six patients in the previously reported cases of glandular papilloma underwent lobectomy, and four glandular papillomas were removed through endobronchial interventions. No recurrence was reported after either treatment modality, with follow-up periods ranging between 1 year and 11 years.
