Although Todd and Thompson had recorded methemoglobinemia in chronic copper poisoning in sheep in 1961 (1), the occurrence of methemoglobinemia in man has been reported only recently in two patients who, it was suspected, had had lethal acute copper intoxication during hemodialysis (2). The evidence of copper intoxication in these patients was circumstantial and retrospective; blood copper levels were not measured in either of them. We wish to report a case of methemoglobinemia in acute copper sulfate poisoning in a patient who came under our observation recently, with direct evidence of copper poisoning.
