“…Benign papillary or papillary/cystic neoplasms arising from the excretory duct epithelium of the minor salivary glands are uncommon, 1,2 and few reports have focused on their molecular characteristics 2 . Recently, three groups have genetically studied a series of sialadenoma papilliferum (SP), SP‐like intraductal papillary tumor (SP‐like tumor lacking an exophytic squamous papilloma component), 3 exophytic ductal papilloma (EDP), 4 intraductal papillary mucinous neoplasm (IPMN), intraductal papilloma (IP) and/or cystadenoma, 3–5 although no cases of inverted ductal papilloma (IDP) were included. Here, presenting a new case of oral IDP, we would like to extend the list of salivary gland tumors harboring an activating mutation in HRAS .…”
