Caliber-persistent Artery: A Case Report

The caliber-persistent labial artery (CPLA) is a vascular anomaly in which a main branch of the artery penetrates the submucosal area of the lip without loss of caliber. It commonly presents as an elevated soft tissue mass and is often pulsatile on manual palpation. Clinical suspicion is important, given the risk of bleeding, either from slight trauma or accidentally if lack of awareness leads to excision of the lesion owing to an incorrect diagnosis. CPLA should be considered in the differential diagnosis of any lesion affecting the lip, especially to differentiate from mucocele or squamous cell carcinoma. This particular case of CPLA in the upper lip of a girl presents a both unusual and interesting clinical picture and could provide essential diagnostic and procedural information.
