This document provides descriptions and distinguishing characteristics of various white and red lesions that may appear in the oral cavity. It describes conditions such as leukoplakia, lichen planus, oral thrush, hairy leukoplakia, chemical burns, and more. For each condition, it outlines where in the mouth they typically appear, their appearance (color, texture, etc.), potential causes, how to diagnose, and important histopathological findings. The goal is to differentiate between these various oral lesions based on clinical and microscopic examination.
