Sclerosing hemangioma of the tongue: report of case.

An instance of a large sclerosing-type hemangioma of the tongue is reported with the pathogenesis of the lesion. A review of the literature suggests that the process is part of the natural evolution of hemangiomas and merely represents a regressive phenomenon. In the oral cavity where there are no areas that are free of repeated trauma, chronic irritation may incite the fibrosis and other retrogressive features that have been described.
