Caliber persistent artery is a rarely reported lesion which prefers, given the underpinned literature, the labial arteries. This paper reports a very rare case of an isolated palatal ulcerative lesion in a non-insulin dependent diabetic patient. The patient refused to run any radiological tests, other than the periapical radiograph, but consented the incisional biopsy. Therefore, histochemical and immunohsitochemical stains were ushered to establish, non-invasively, a diagnosis. Accordingly, this paper explores the diagnostics and differential diagnosis of caliber persistent artery and reviews briefly the previously reported cases.
