What is a Lesion?

A lesion refers to any visible or palpable change in the skin. Understanding basic lesion types helps you describe what you are seeing and guides your clinical thinking.

Common lesion types include macules (flat areas of colour), papules (small raised bumps), and nodules (deeper, larger lesions). While you are not expected to diagnose complex dermatological conditions, recognising these basic categories allows you to communicate findings clearly.

Describing lesions accurately also helps identify patterns and differentiate between common conditions such as acne, rosacea, or benign growths.

This forms the foundation for more advanced dermatological assessment.
