Flat Lesions: Macules and Patches
Macules are small, flat color changes in your skin less than 1 cm across. Larger flat areas are called patches. These can be lighter or darker than your normal skin tone. Common examples include freckles, age spots, and some birthmarks. While many are harmless, sudden changes or new spots should be checked by a doctor.
Raised Lesions: Papules, Plaques, and Nodules
Papules are small raised bumps less than 1 cm wide. When papules group together or grow larger, they form plaques. Nodules are larger, deeper bumps. These raised lesions can have various causes, from acne to more serious conditions like skin cancer. The size, shape, color, and feel of these bumps provide important clues to their cause.
Fluid-Filled Lesions: Vesicles, Bullae, and Pustules
Some skin lesions contain fluid. Small fluid-filled bumps are called vesicles, while larger ones are bullae. These often occur with viral infections like chickenpox. Pustules contain pus and are common in conditions like acne. Any sudden outbreak of fluid-filled lesions warrants medical attention.
