Arsenic Dermatitis

Arsenic dermatitis is a skin condition caused by exposure to arsenic, a toxic element found naturally in the Earth’s crust and some human activities. This dermatitis can occur when the skin comes into contact with arsenic-containing substances, such as certain pesticides, industrial chemicals, or contaminated water. Arsenic dermatitis can lead to discomfort, itching, and redness on the affected skin areas. Understanding its causes, symptoms, and treatment is essential to manage this condition effectively.

Types of Arsenic Dermatitis

  1. Acute Arsenic Dermatitis: Acute arsenic dermatitis occurs shortly after exposure to high levels of arsenic. This type of dermatitis can lead to sudden and severe symptoms, including redness, itching, and blistering of the skin. In extreme cases, acute arsenic dermatitis can result in systemic toxicity, affecting other organs and leading to life-threatening conditions.
  2. Chronic Arsenic Dermatitis: Chronic arsenic dermatitis develops over a prolonged period of low-level arsenic exposure. The symptoms may not be as intense as in acute cases, but they can persist for an extended period. Chronic arsenic exposure can lead to a variety of skin manifestations, such as hyperpigmentation (darkening of the skin), hyperkeratosis (thickening of the skin), and skin lesions.

Causes

Causes of arsenic dermatitis
