ANGIOSARCOMA, PORPHYRIA-CUTANEA-TARDA, AND PROBABLE CHLORACNE IN A WORKER EXPOSED TO WASTE OIL CONTAMINATED WITH 2,3,7,8-TETRACHLORODIBENZO-P-DIOXIN

A worker developed angiosarcoma, porphyria cutanea tarda, and skin les ions characteristic of mild chloracne. About 10 years earlier he had b een employed at a truck terminal in Saint Louis, Missouri, at a time w hen it was sprayed with waste oil contaminated with 2,3,7,8-tetrachlor odibenzo-p-dioxin (TCDD). The occurrence of these three rare condition s in a single exposed worker supports the aetiological relation betwee n environmental exposure to TCDD and the subsequent development of sof t tissue sarcoma and porphyria cutanea tarda.
