Caliber-Persistent Labial Artery about a case

Abstract

The labial artery of persistent caliber is a relatively rare lesion that can be found in different organs such as the stomach, jejunum or lips; which appears as an arterial branch of abnormally large diameter for its superficial situation. The persistence of the caliber of the labial artery usually occurs in the lower lip, but there are reports of its location in the upper lip, palate and buccal vestibule. It is an entity of controversial etiology, clinically manifested as a swelling or erosion that must be taken into account whenever an intraoral examination is performed to avoid invasive treatments that cause profuse bleeding. The objective of this publication is to report the case of a patient who presented persistent arterial caliber in the upper lip.
