Lesion Morphology

Secondary lesions are those lesions that are characteristically brought about by modification of the primary lesion either by the individual with the lesion or through the natural evolution of the lesion in the environment. Tasneem Poonawalla, M. Core Concepts of Pediatrics. Secondary lesions Secondary lesions are those lesions that are characteristically brought about by modification of the primary lesion either by the individual with the lesion or through the natural evolution of the lesion in the environment. Atrophy : localized shrinking of the skin which results in paper-thin, wrinkled skin with easily visible vessels.

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. 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.

Written and peer-reviewed by physicians—but use at your own risk. Read our disclaimer. Dermatology is the branch of medicine concerned with the skin , hair , and nails , as well as the conditions associated with them. In the United States, the most common conditions seen by dermatologists include acne , actinic keratoses , non- melanoma skin cancers, benign tumors , and contact dermatitis. Skin lesions may be primary or secondary.


Primary: Macule – flat, circumscribed skin discoloration that lacks surface elevation or depression. (freckle, café au lait). Papule – elevated, solid lesion <​ cm.


An extensive language has been developed to standardize the description of skin lesions, including. Lesion type sometimes called primary morphology. Lesion configuration sometimes called secondary morphology. Location and distribution. Macules represent a change in color and are not raised or depressed compared to the skin surface.

Primary skin lesions are those which develop as a direct result of the disease process. Secondary lesions are those which evolve from primary lesions or develop as a consequence of the patient's activities. This classification is naturally artificial; the same lesion type might be a primary lesion in one disease but a secondary lesion in another eg alopecia is a primary lesion in canine hypothyroidism [direct consequence of lack of thyroxine] but a secondary lesion in feline flea allergy [caused by the patient: hair removed by the itchy cat]. Do not confuse the term "secondary lesion" with "secondary pyoderma". The latter term implies a bacterial infection which is complicating an underlying skin disease common examples in dogs include allergy or demodicosis but that secondary pyoderma may present with primary lesions such as papules and pustules.

    Primary skin lesions are present at the onset of a disease. In contrast, secondary skin lesions result from changes over time caused by disease progression.
