Paediatric plastic bronchitis in an atopic child; A case report from East Africa.

Paediatric plastic bronchitis (PB) is a rare disease characterized by the presence or expectoration of branching airway casts usually in children with cardiac conditions and allergy. It is thought to be due to obstruction or altered drainage of the lymphatics in those with cardiac conditions. Obstruction can be diffuse and thus fatal if untreated.
