"Porcine bronchus" diagnosed in neonatal period.

"Porcine bronchus" is a right upper lobe bronchus arising directly from the trachea. This is an infrequent congenital abnormality and it usually represents the displaced origin of a normal bronchus. We herewith report a case of a child who was diagnosed to have tracheal bronchus in neonatal period and followed subsequently until 13 months of age.
