Abstract
A case of a subacute, distal, symmetrical polyneuropathy in a housewife is reported. The fact that the polyneuropathy affected almost only the motor fibers led us to suspect an exogenous intoxication. Blood Pb level and the urinary excretion of Pb after i.v. EDTA were very high. The blood Pb levels were normal in the husband and children of the patient. A glazed cup used only by the patient to keep tea with lemon juice released toxic amounts of Pb with acidic solutions. The manufacturer of the cup was not identified by the inquiring authorities and therefore almost certainly other Pb-releasing cups are still in use. The importance of suspecting Pb intoxication in individuals not professionally exposed is stressed.
