Objectives: One case of caliber persistent artery is reported in a facial area where it has not been previously described in the literature. The importance of ultrasonography in the diagnostic confirmation of this entity is emphasized. An analysis of previously reported cases on oral and facial caliber persistent artery was also conducted. Methods: A case of a patient with caliber persistent artery in the buccal region of the face, studied by ultrasonography is described. Also, a MEDLINE, EMBASE and SCOPUS search was conducted from 1973 to 2019 using the terms “caliber persistent artery”, “vascular anomalies” “vascular lesions”, also together with “oral” and “facial”. A total of 34 articles have been reviewed. Results: At the age of 62 years old, a male patient presented a pulsatile swelling in the left buccal region of the face. Gray-scale ultrasound evaluation showed a luminal structure in the subcutaneous tissue. The spectral Doppler mode showed a systolic diastolic waveform, determining its arterial nature. The reviewed literature reveals that up to date, there are 275 cases of caliber persistent artery published and 305 diagnosed lesions related to the oral and facial structures, with males and females being affected quite symmetrically. Almost all reported cases in the literature correspond to caliber persistent artery affecting the lips mucosa and just seven cases were related to other structures. The affectation was almost equal between upper and lower lip, being the former affected in 49.6% of the cases, meanwhile the latter in 50.4% of the cases published. Conclusions: This is the first case reported of caliber persistent artery in the buccal region of the face, which is predominantly seen in the lips. Other few cases of oral and facial caliber persistent artery have been reported affecting the oral buccal vestibule, and also palate, nasal vestibule and eyelids. Ultrasonography should be considered as the imaging modality of choice for confirming its diagnosis instead of unnecessary surgical procedure and biopsy. *Correspondence to: Jorge Pinares Toledo, Área de Radiología, Departamento de Patología y Medicina Oral, Facultad de Odontología, Universidad de Chile, Sergio Livingstone Polhammer 943, Independencia, Santiago, Chile, Tel: +56 9 62401137; E-mail: jpinares@odontologia.uchile.cl
