Methemoglobinemia is caused by a congenital or acquired increase of methemoglobin (MetHb).
A 11-months-old child came for episodes of peripheral cyanosis. The only altered exam was MetHb level, but
non-pathogenic homozygous mutation of cytochrome B5-reductase gene.
Our patient had begun to show cyanosis since the assumption of vegetable broth. Our case report is a warning
to investigate the children’s environmental conditions
