The medical term for depigmented patches of skin interspersed with normal skin is vitiligo. This condition is characterized by the loss of pigment in the skin, resulting in white patches that can appear anywhere on the body. Vitiligo is an autoimmune disorder where the immune system attacks melanocytes, the cells responsible for producing melanin, leading to the characteristic depigmentation.
The fibrous protein that fills cells in the epidermis is called keratin. Keratin is a hard, fibrous protein that provides structural integrity and protection to the skin, hair, and nails. It plays a crucial role in the epidermis by forming a protective barrier against environmental damage and maintaining the skin's hydration.
The medical term for excessive epidermal cells and silvery scales is psoriasis. Psoriasis is an autoimmune skin disorder characterized by thick, red patches covered with silvery scales, often appearing on the scalp, elbows, and knees. It is caused by the rapid proliferation of skin cells, leading to the buildup of these scales.
Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease that can affect various systems in the body. Common symptoms include fatigue, joint pain, and rashes, particularly across the nose and cheeks. While there is no cure for SLE, treatments are available to help manage symptoms and improve quality of life. The disease is characterized by the formation of autoantibodies that attack healthy tissues, leading to inflammation and damage. SLE is the most prevalent form of lupus, affecting approximately 70% of individuals diagnosed with lupus.
