Sialadenoma Papilliferum - 30/01/21

Abstract |
Sialadenoma papilliferum (SP) is a rare, benign salivary gland neoplasm sharing similar histopathologic features and harboring the same genetic alterations, BRAF V600E or HRAS mutations, with syringocystadenoma papilliferum. SP most commonly occurs in the hard palate and in older adults. Clinically, SP is most likely to be diagnosed as a squamous papilloma. Microscopically, SP shows an exophytic papillary epithelial proliferation and a contiguously endophytic ductal proliferation. Two distinct subtypes are identified: classic SP and oncocytic SP. Conservative surgical treatment seems to be adequate with a low recurrence. SOX10 immunohistochemistry and BRAF analysis may be useful in differential diagnosis.
