Methemoglobinemia is an alteration of the oxidative state of hemoglobin. When methemoglobin values rise above 10%, the symptoms and signs related to this condition appear, such as cyanosis, respiratory problems, fatigue and headache. Acquired methemoglobinemia is characterized by the sudden onset of cyanosis in a previous healthy child, which can be due to exposure to medications or chemical substances including nitrates, copper, sulfates, chlorites, chloramines and chlorates which can be present in food and water. We illustrate two cases of acquired methemoglobinemia related to nitrate ingestion from a vegetable source.
