For green, blue and violet conditions, a review can be found here. For black and white conditions, a review can be found here. For brown and grey conditions, a review can be found here. Note that any color can be a normal variant for an individual or is physiologic for a given state. The skin is the largest organ of the body. It can be easily examined but for many clinicians continues to be difficult to describe what they are seeing. Analogies and comparisons are often used such as “It sort of looks like XXX,” or “It looks like atopic dermatitis but also YYY.” Skin lesions are described in many terms including morphology, size (using standard measurements), demarcation (well- or not well- demarcated), location, distribution and color. Morphologically lesions may be uniform or not uniform. Primary morphology terms include: “Macule – flat lesion less than 1 cm, without elevation or depression Patch – flat lesion greater than 1 cm, without elevation or depression Plaque – flat, elevated lesion, usually greater than 1 cm Papule – elevated, solid lesion less than 1 cm Nodule – elevated, solid lesion greater than 1 cm Vesicle – elevated, fluid-filled lesion, usually less than 1 cm Pustule – elevated, pus-filled lesion, usual...
