Congenital sulfhemoglobin and transient methemoglobinemia secondary to diarrhoea.

Sulfhemoglobinemia and Methemoglobinemia are common causes of cyanosis arising due to accumulation of abnormal heme pigment. We present an unusual case of congenital sulfhemoglobinemia along with diarrhoea induced methemo-globinemia in a neonate. A high index of suspicion and a proper diagnostic approach is needed to determine the true frequency of their occurrence together.
