Rare vascular proliferations of the oral mucosa

Benign vascular lesions-malformative, reactive, and neoplastic-are fairly common in the oral soft tissues; nevertheless, extravascular papillary endothelial hyperplasia and sinusoidal hemangioma have not been reported in this location. To our knowledge, a single case of intraoral spindle cell hemangioma has appeared in the literature. This report deals with histopathological features of these rare vascular proliferations involving the oral mucosa.
