Chronic arsenic poisoning: a woman with multiple Bowen's disease and palmoplantar keratosis

JTHT Yu 余浩德 and WY Lam 林偉業

Abstract
A 62-year-old Chinese lady presented with non-itchy, asymptomatic scaly plaques on trunks and limbs for eight years together with palmoplantar keratosis. She was treated with Chinese proprietary medicine for asthma 30 years ago. A diagnosis of multiple Bowen's disease with arsenic keratosis was made based on clinicopathological findings. Regular follow-up will be given to detect any cutaneous malignant changes.
