title: Interrelationships of calibre persistent artery, chronic ulcer and squamous cancer of the lower lip.
abstract: Calibre persistent arteries come close to internal and external body surfaces without ramification or reduction of their calibre. In the stomach and jejunum they may give rise to fatal haemorrhage and in the lower lip to a chronic ulcer simulating cancer. In the present case the histological findings suggest a causal connection between an artery of persistent calibre, a chronic ulcer, and squamous cancer of the lower lip.
