Abstract
This is a human case report of documented exposure to polybrominated biphenyls (PBBs), with serial PBB determinations, obtained over an 11 year period, and signs and symptoms characteristic of PBB exposure, culminating in cancer. No epidemiological studies of PBB and cancer are available, but structure- activity relationships and animal studies were predictive of malignancy. The patient did not have the risk factors of alcoholism or cigarette smoking.
