Intraductal papilloma of salivary gland (also known as an inverted ductal papilloma or sialadenoma papilliferum) is a benign relatively rare salivary gland tumor. '
Epidemiology
They typically arise in adulthood and there may be a slight male predilection.
Pathology
They may show a characteristic endophytic growth pattern and are composed of bulbous papillary projections of basaloid cells dilating and filling the superficial portion of the excretory duct. Histologically, inverted ductal papillomas resemble inverted papilloma of the nose and paranasal sinuses.
Location
They are more commonly encountered in minor salivary glands.
