A Case of Multiple SCCs in situ and BCC Induced Probably by Chronic Exposure to Arsenic-containing Pills (Hwan-Yak) / 대한피부과학회지

ABSTRACT

Not legally, arsenic has been used for various medical purposes. Chronic exposure to arsenic can induce different kinds of cutaneous diseases, including arsenic keratosis, Bowen's disease, squamous cell carcinoma (SCC), basal cell carcinoma (BCC), and other pigment disorders. Also, arsenic induces internal malignancies, including tumors of the pulmonary and urogenital systems. To prevent these malignancies, the use of arsenics should be strictly prohibited. We describe a 72-year-old man who developed SCC in situ and BCC after chronic exposure to arsenics.
