Inorganic lead poisoning in an adult.

Lead poisoning is uncommon in the adult population, but must be considered in the differential diagnosis of patients with abdominal pain of obscure etiology. In this paper we present a 38-yr-old male with abdominal pain, a history of alcohol abuse, and exposure to the virus responsible for acquired immunodeficiency syndrome. The cause of pain was elusive until his occupation as a housepainter was appreciated. The diagnosis of lead poisoning then was considered and confirmed by an elevated blood lead level and symptomatic response to therapy. With the increase in renovation of old buildings, it is likely that the incidence of lead poisoning will become more common.
