Idiopathic gingival papillokeratosis with crypt formation (IGPC) is a new and a very rare benign entity, clinically characterized by white-yellowish plaques with papillary architecture located in the upper labial gingiva of adolescent patients. The condition generally exhibits a bilateral symmetrical distribution and is asymptomatic. We report two new cases, one with a classic presentation and the other in an older individual.

Material And Methods: 20 oral medicine specialists from the national registry of specialists in Chile and 20 general dental practitioners were invited to participate. Each participant reviewed 33 cases with digital images of oral mucosa lesions and was asked to submit diagnostic hypotheses.
Nearly 90% of oral cancers are characterized as oral squamous cell carcinoma (OSCC), representing the sixth most common type of cancer. OSCC usually evolves from oral potentially malignant disorders that, in some cases, are histologically consistent with a oral dysplasia. The levels of 1α,25 dihydroxyvitamin D3 (1,25-(OH)2D3; calcitriol), the active form of vitamin D3, have been shown to be decreased in patients with oral dysplasia and OSCC.

We recently reported that oral dysplasia is associated with aberrant activation of the Wnt/β-catenin pathway, due to overexpression of Wnt ligands in a Porcupine (PORCN)-dependent manner. Pharmacologic inhibition of PORCN precludes Wnt secretion and has been proposed as a potential therapeutic approach to treat established cancers.
