A case of psoriasis with arsenic poisoning is reported. The clinical manifestations included hyperpigmentation on the trunk, limbs, face and neck, and hyperkeratosis on palms and soles. The laboratory tests showed abnormal hepatic function and a high level of urine arsenate. Based on the clinical manifestations, laboratory tests and the effective treatment responses to sodium dimercaptopropane sulfonate, the patient was diagnosed as psoriasis accompanied with arsenic poisoning. The present case and literature review demonstrate that arsenate has beneficial effects by suppressing keratinocyte proliferation and inducing apoptosis. At same time arsenate could cause accumulation poisoning. In order to maximize the therapeutic efficacy and mini- mize the side effects, more basic and clinical studies should be conducted to determine the best dose of arsenate. In addition to closely monitoring the administration of arsenate containing medication, a standard for its clinical usage should be established.
