Abstract:
Chronic arsenism usually occurs after a long-term unawareness of arsenic exposure from environment, occupation, food, and water. We here reported 3 cases with diffused arsenic keratosis and skin cancers derived from long-term arsenic medication ingestion. In these cases, hyperkeratotic skin lesions were initially found on palms and soles, slowly progressed to every part of the skin and lasted maximally for over 30 years. Skin cancers were diagnosed and removed intermittently within decades, but with no malignancies in other organs. Oral retinoids combing with topical 5- fluorouracil and photodynamic treatment yielded a desirable outcome.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
