Discrepancies in the terminology of elementary lesions persist when texts from Dermatology and Semiology books are compared, which can cause some confusion in both the teaching of undergraduate medical students and the learning acquired by professionals in the field. This review aims to compare and clarify the differences in the description of elementary lesions by many authors, used as references for specialists in dermatology. As regards elementary lesions, used in the teaching of semiology within the Dermatology course, historically, two semantic models were initially described: the Essentialist model, proposed by Robert Willan , followed by Thomas Bateman at the end of the eighteenth century, and the Nominalist model, proposed by Ferdinand Hebra in the nineteenth century. The Essentialist model considers the description of the lesion, taking into consideration its morphological characteristics, such as elevation, consistency, size, and depth, as well as its clinical evolution, that is, the transformation of the lesion in its lifespan and not only the description of the lesion at the exact moment in which it is observed. By contrast, in the Nominalist model, Hebra excluded the morphological evolution of the elementary lesion and objectively considered a clear meaning referent to the terminology of known criteria found in the lesion upon observation "status praesens".

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.

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.

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].

    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.

    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.
