Resumo: Caliber-persistent artery (CPA) is a vascular malformation in which a branch of the labial artery penetrates into the submucosal tissue maintaining its original caliber. It can be pulsatile and affect various parts of the body, but only a few cases are in the oral cavity. Here we report two cases of CPA on the lower lip. The first one is a 45-year-old female presenting a whitish sessile papule with a clinical diagnosis of mucocele. The second one is a 68-year-old male presenting with a soft sessile nodule with a clinical diagnosis of fibroma. In both cases an excisional biopsy was performed, and significant bleeding was observed in the second one. Microscopically, a thick-walled artery was present in the lamina propria. The final diagnosis of CPA was assigned, and the patients were lost to the follow up. Knowledge of this lesion by clinicians can avoid misdiagnosis and difficulties during biopsy.
