Causes of Lichen planus
Lichen planus is caused by an abnormal immune response in which the body’s own defenses, especially T lymphocytes, attack cells in the skin, mucous membranes, hair follicles, or nails. In most cases, it is not caused by a single factor but by a combination of immune dysregulation, genetic susceptibility, and one or more triggers such…

Causes of Jaundice
Jaundice is treated by addressing the biological cause of bilirubin buildup rather than by treating the yellow color alone. The main treatment approaches depend on whether the underlying problem is excessive red blood cell breakdown, liver cell dysfunction, impaired bilirubin conjugation, or obstruction of bile flow. Management may involve medical treatment of liver disease, relief…

Causes of Contact dermatitis
Contact dermatitis is caused by direct contact between the skin and a substance or physical agent that either damages the skin barrier or provokes an immune response in the skin. In practical terms, the condition develops when the outer protective layer of the skin is disrupted by an irritant, or when the immune system identifies…

Causes of Chickenpox
Chickenpox is caused by infection with the varicella-zoster virus (VZV), a human herpesvirus that spreads from person to person and then enters cells in the skin and nervous system. The illness develops when the virus is transmitted, replicates inside the body, and triggers the characteristic rash and systemic immune response. In practical terms, chickenpox does…

Causes of Carbuncle
What causes carbuncle? A carbuncle develops when a bacterial infection, usually involving Staphylococcus aureus , spreads through several adjacent hair follicles and the surrounding skin, producing a larger, deeper pocket of inflammation and pus than a simple boil. The condition does not arise from one single event; it reflects a sequence of biological processes in…

Causes of Bullous pemphigoid
Bullous pemphigoid is caused by an autoimmune reaction in which the immune system mistakenly attacks proteins that anchor the outer layer of the skin to the deeper layers beneath it. This attack weakens the connection between skin layers, allowing fluid to collect and form large, tense blisters. The condition develops through a combination of biological…

Causes of Basal cell carcinoma
Basal cell carcinoma develops primarily because of damage to the DNA of basal cells in the skin, most often from long-term ultraviolet (UV) exposure. When these cells accumulate genetic errors that disrupt normal growth control, they can begin dividing in an uncontrolled way and form a cancerous tumor. The condition does not arise from a…
