Skin manifestations refer to visible changes or abnormalities on the skin that can indicate underlying health issues. These changes can include rashes, lesions, discoloration, or swelling. Common causes of skin manifestations include infections, allergies, autoimmune diseases, and environmental factors. Diagnosis of skin manifestations often involves a physical examination and may require additional tests, such as skin biopsies or allergy tests. Treatment varies based on the underlying cause and may include topical medications, systemic treatments, or lifestyle modifications. Understanding skin manifestations is essential for early detection and management of potential health concerns.
