“…Sialadenoma papilliferum has been considered to be a benign tumor with limited potential for local aggressiveness. Based on 20 reported cases with adequate follow up, two lesions recurred at 3 years: one from the buccal mucosa 22 and one from the junction of the hard and soft palate 23 . An extremely rare case, however, of sialadenoma papilliferum of the palate with epithelial–myoepithelial carcinoma and high‐grade carcinoma has recently been reported 24 .…”

Presented herein is the second case of sialadenoma papilliferum of the bronchus in a 75-year-old man. The bronchial tumor had an exophytic papillary lesion protruding into the lumen of the ostial region of the right superior lobe bronchus on chest CT and bronchoscopy. Grossly, the resected tumor was pedunculated, 5 x 3 x 3 mm in size and consisted of both an exophytic papillary lesion protruding into the bronchial lumen and a glandular component in the bronchial submucosa. Histologically, the papillary structures were lined by ciliated or non-ciliated columnar epithelium and metaplastic non-keratinizing stratified squamous epithelium. The submucosal glandular components were well circumscribed beneath and in continuity with the papillary lesion. The glandular components of cysts and duct-like structures were lined by a double-layer epithelium composed of luminal cells and basal cells. Sialadenoma papilliferum is a rarely recognized salivary gland tumor, mostly occurring at intraoral mucosal sites including the hard and soft palate and buccal mucosa. There have been sporadic cases of sialadenoma papilliferum of the esophagus, nasopharynx and nasal cavity. To the authors' knowledge only one case of sialadenoma papilliferum of the bronchus has been reported previously.

“…It is both an exophytic and endophytic papillary lesion histologically resembling syringocystadenoma papilliferum of sweat gland. The tumor is considered benign although rare recurrent cases have been reported [2, 3]. Three cases of malignant transformation of sialadenoma papilliferum have been described in the literature [4–6].…”

Sialadenoma papilliferum is a rare tumor, primarily of minor salivary gland origin, first described by Abrams and Finck (Cancer 24:1057–63, 1969). It is both an exophytic and endophytic papillary lesion histologically resembling syringocystadenoma papilliferum of sweat gland. The tumor is considered benign although rare recurrent cases have been reported. Three cases of malignant transformation of sialadenoma papilliferum have been described in the literature. We report a high grade mucoepidermoid carcinoma arising in a background of sialadenoma papilliferum, at the base of the tongue, an unusual location for minor salivary gland neoplasms. Eleven months after excision and nodal dissection, there is no evidence of recurrence or metastasis.

“…The surface of the tumor is covered by acanthotic stratified squamous epithelium, which merges into the papillary fronds formed by the ductal proliferation in the deep areas. According to the approximately 50 reported cases, SP is considered to be a benign tumor with an exceptionally good prognosis, although post-operative recurrence was observed in two cases [23,24]. Solomon et al [27] reported an intra-oral malignant neoplasm as a possible malignant SP, but subsequent studies have discounted their interpretation [3,9].…”

Malignant transformation of sialadenoma papilliferum of the palate: a case report

et al. 2004

View full text Add to dashboard Cite

We report a case of a 79-year-old woman with an unusual salivary gland tumor that developed at the junction between the soft and hard palates. The tumor consisted of sialadenoma papilliferum (SP) with areas of an epithelial-myoepithelial carcinoma (EMC) component and a high-grade carcinoma component. There were also transitional regions among the SP, the EMC and the high-grade carcinoma components. The high-grade carcinoma component, which was similar to invasive micropapillary carcinoma of the breast, infiltrated into the right parapharyngeal space and metastasized to the lungs and cervical vertebrae. The high-grade carcinoma cells were positively immunostained for p53 protein. SP has been considered to be a benign tumor with exceptionally good prognosis, and, to the best of our knowledge, there has never been a confirmed case of malignant SP. This is the first report of SP with a definite malignant component.
