Irritant contact dermatitis is the most common form of contact dermatitis and the most common occupational skin disease. This review provides a comprehensive summary of the endogenous and exogenous factors that play a role in the pathogenesis of irritant contact dermatitis.
Recent Findings
In conjunction with avoidance of irritants, barrier protection, and regular application of moisturizers, management now emphasizes the importance of primary prevention through educational initiatives in high-risk workplaces.

Cinnamon is derived from the bark of cinnamon tree, with cinnamic aldehyde being the main constituent as well as trans-cinnamic acid and cinnamic alcohol. Allergic contact dermatitis (ACD) to cinnamon is rare, usually presenting as a localized dermatitis; however, systemic dermatitis 1 and urticaria 2 have been reported.We report an unusual case of ACD following daily ingestion of cinnamon in a chai-tea drink in a 38-year-old female with an 18-month history of persistent cheilitis affecting both lips. Past medical history included allergic rhinitis. Before her ACD, she had been diagnosed with actinic cheilitis; however, this had cleared with a course of Efudix cream. There was no improvement with cessation of
