Sulfur mustard or mustard gas has been widely used as a chemical weapon in the first world war and Iraq-Iran war. It causes acute and chronic complications in lungs, eyes and skin. In skin, mustard is toxic, mutagenic, and carcinogenic via alkylation of cellular proteins in enzymes, cell membranes, cytoplasm and particularly cell nucleus as well as in DNA components of the epidermis, dermis and skin appendages. Herein, we report a 37-year-old man who developed widespread blistering on his right thigh after sulfur mustard exposure in 1988. Now multiple cherry angiomas, decreased hair growth and pigmentary disorder are visible at the site of previous injury.
