Identification and classification of a patient's skin lesions are important steps in the diagnosis of any skin disorder. The numerous descriptive terms used in dermatology can be overwhelming and at times confusing as there are some variations in the use and meaning of these words in the literature.1 However, a few simple terms can be used to describe the cutaneous findings in most skin diseases. Using proper terminology to describe skin findings is essential for both documentation and communication with other clinicians. The effort to use precise descriptive terms also encourages a clinician to look with more care and more closely at a patient's skin lesions. The key features of skin lesions are (1) the type of lesion, (2) secondary changes to the surface of the lesion, (3) the color of the lesion, (4) the shape of the lesion, and (5) the arrangement and distribution of the lesions.
