This document discusses aphthous ulcers, also known as canker sores, which are characterized by recurring, painful ulcers in the mouth. It describes the three main types: minor aphthous ulcers, which are less than 10mm and heal within 2 weeks; major aphthous ulcers, which are larger than 10mm and can take over 6 weeks to heal, often leaving scars; and herpetiform ulcers, which present as multiple small ulcers that may join together into larger ones and persist for 1-3 years. The document provides details on symptoms, locations in the mouth, appearances, durations, and histopathology of the different types of aphthous ulcers.
