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...

Sialadenoma papilliferum is a rare benign salivary gland tumor. We present an unusual case of sialadenoma papilliferum of the parotid gland, discuss clinical presentation, diagnostic challenges, and review of the literature. A 65-year-old male smoker presented with a large, exophytic, fungating, painless mass in the tail parotid for 8 years. The tumor developed an exophytic component 2 years be...

Sialadenoma papilliferum is a rare salivary gland tumor clinically resembling papilloma originating probably from the excretory duct. It is characterized by a biphasic growth pattern of exophytic squamous component and endophytic glandular component. We report a rare case of sialadenoma papilliferum in the floor of the mouth with epithelial dysplasia with pertinent review of literature. The pre...

Background. Sialadenoma papilliferum (SP) is a rare benign epithelial tumor of salivary gland origin, its diagnosis being potentially challenging. It was first described by Abrams and Finck in 1969 as an analog the cutaneous syringocystadenoma papilliferum. The aim this comprehensive review to highlight clinical histopathological diagnostic aspects intraoral SP, analyzing cases previously repor...

Ductal papillomas have unique papillary features arising from the salivary gland duct system. They comprise three rare benign adenomas, namely, inverted ductal papilloma, sialadenoma papilliferum, and intraductal papilloma. Intraductal papilloma is an extremely rare benign salivary gland tumor that occurs most commonly in the minor salivary glands. Here, we are presenting a case report of intra...
