[The authors describe a patient’s case, who was hospitalized with stomach pain. During the study of the patient, a microscopic examination of the blood vessel helped the diagnosis. Basophil eruptions of red blood cells raised the suspicion of lead poisoning, which was confirmed by a high lead level in the serum. The source of the lead poisoning was a lead covered jug, in which the family stored a homemade syrups that is popular among Hungarians. At several members of the family, who had been consumed the syrup, we measured high non-symptomatic lead levels. The patient and his family were successfully treated with a chelating therapy. The au-thors summarize the symptoms of lead poisoning through a case report. Call the attention that excessive lead exposure in Hungary is rarely recognized, and the symptoms are often misleading.]
