Oral focal mucinosis of the tongue: A rare clinical entity?

Oral focal mucinosis (OFM) is regarded as a very rare clinical entity with only 62 cases previously reported in the literature. The majority of these cases have been present on gingiva and only 3 cases have been diagnosed on the tongue. The clinical appearance of OFM is relatively non-specific and resembles other and more prevalent conditions like fibroepithelial hyperplasia or other reactive mucosal lesions. The present case report describes OFM in the tongue in an 88-year-old woman. The report addresses the diagnostic considerations of OFM, but also if the lesion is really as rare as the literature indicates.
