They are: Primary skin lesions: These lesions are present at the time or birth or acquired during the lifetime. If there is an added significance to regions within the tissue—such as in neural injuries where different locations correspond to different neurological deficits—they are further classified by location. Primary skin lesions are present from birth or are acquired during a person’s lifetime. Of the 5,127 patients referred to our dermatology clinic, 48 patients with generalized pruritus without primary skin lesions were evaluated. Skin Lesions: Definition A skin lesion is a superficial growth or patch of the skin that does not resemble the area surrounding it. Common benign skin lesions of melanocytic origin include the ephilis, lentigo simplex, and melanocytic naevus (mole). Primary skin lesions are present at the onset of a disease. epidermolysis bullosa, bullous impetigo). Skin lesions are areas of skin that look different from the surrounding area. These 2 types A skin condition, also known as cutaneous condition, is any medical condition that affects the integumentary system—the organ system that encloses the body and includes skin, hair, nails, and related muscle and glands.
