“…In the oral cavity, it appears as a white-coloured, exophytic, papillary lesion of the mucosa [1,7]. In the three reports analysed, the macroscopic appearance is similar, being described as a well-demarcated, white, papillary or verrucous, sessile to a pedunculated lesion of the trachea or the bronchus [3][4][5]. It shows a histopathological biphasic growth with an exophytic papillary squamous component and a solid/cystic part.…”

“…The described findings are consistent with a cystic papillary neoplasm of undetermined malignant potential (probably, low), most likely originating from bronchial glands. The final dia-gnosis was sialadenoma papilliferum (SP), a rare subset of ductal papilloma of minor salivary gland origin, also described in the bronchi [3][4][5]. In our opinion, this tumour could be considered as a "salivary gland type bronchial neoplasm".…”

Sialadenoma papilliferum is a benign salivary tumour which rarely occurs in the bronchial tree. Up to now, only four cases of pulmonary papillary sialadenoma have been reported in the literature. We discuss the case of a male patient with an accidental finding of a middle lobe nodule. The patient underwent a minimally invasive anatomical resection of the lobe to remove the lesion; the postoperative course was regular, and he was healthy at the last follow-up.

Sialadenoma papilliferum (SP) is a rare salivary gland tumor mostly reported in the oral cavity. Here we describe a bronchial SP in the left upper lobe bronchus of a 10-year-old boy. At bronchoscopy, a well-circumscribed polypoid lesion protruding into the bronchial lumen was identified. The tumor was excised, but eventually, the patient had to undergo a sleeve resection after 2 recurrences. Pathology revealed a papillocystic lesion with exophytic and endophytic components. The cells lining the exophytic surface and papillary structures were columnar and squamous, and the cells lining endophytic cystic and papillary structures were cuboidal to columnar, all of which were diffusely reactive with antibodies to SOX10 protein. The presence of basal cells was demonstrated by p63 immunoreactivity. The cells failed to immunohistochemically express BRAF V600E. Fluorescence in situ hybridization analysis revealed no MAML2 or RET gene rearrangement. The patient is alive 24 years after resection with no additional recurrences. Bronchial SP needs to be recognized and distinguished from other benign and malignant salivary gland and pulmonary neoplasms so that patients can receive appropriate treatment and follow-up.
