Oral focal mucinosis: review of the literature and two case reports.

Oral focal mucinosis is a rare condition, clinically characterized by an asymptomatic swelling, without distinct, specific features, which occurs predominantly in adults of the female gender. Its clinical aspect leads to various differential diagnoses, and final diagnosis is only possible by means of histopathological exam, in which a well-delimited myxomatous area containing mucinous material is observed. In the present study, a review of the English-language literature about the lesion, was conducted, covering the period from 1974 to March 2015. We report two new cases, thereby contributing to the knowledge and differential diagnosis of this entity.
