Background: Chengal is a resistant rainforest hardwood that is commonly used in South-East Asia for the construction of boats, bridges, house structures and furniture. It contains oligostilbenoids, phenolics, quinones and resins.

Aims:  To describe a case of occupational asthma (OA) related to chengal wood dust.

Methods:  The patient was evaluated clinically for asthma in relation to occupational history, serial peak flow monitoring and specific inhalation challenge (SIC) test.

Results: Peak flow monitoring showed significant deterioration during exposure to chengal wood dust at work. SIC test resulted in an isolated immediate asthmatic reaction.

Conclusions: Exposure to chengal wood dust can lead to OA and possibly rhinitis. The underlying mechanism should be investigated.
