The terminology of skin disorders

Accurate diagnosis of skin disorders is essential for primary care physicians; studies have shown that dermatologic diagnosis by primary care trainees and attending physicians could be improved. Careful attention to the history and a systematic approach to the physical examination are essential to our diagnostic skills. Thorough description of the history and physical findings are valuable for reference as the condition evolves and for communication when referral to a dermatologist is needed. This article reviews the lexicon of skin disorders, beginning with description of the component of skin affected, the primary lesion, the extent and distribution, the characteristics of the lesions, and secondary or special lesions. Careful description of skin color, moisture, turgor, texture, and temperature are emphasized, and definition of skin lesions follows.
