 Abstract


We describe a case of occupational rhinitis and asthma in a 46-year-old carpenter who presented nasal and bronchial symptoms after cedrorana (Cedrelinga catenaeformis Ducke) wood dust exposure. Skin prick tests (SPT) with a battery of common allergens and different kinds of wood, were positive to cedrorana and grass pollen and negative to the other wood extracts. Nasal provocation and exposure challenge tests with
Cedrorana wood dust also gave a positive reaction. IgE-immunoblotting showed two bands of 45 and 78 kDa respectively. This is the fi rst reported case of occupational rhinitis and asthma due to Cedrorana wood dust where an IgE mediated mechanism has been found.

Key words: Allergy. Cedrorana. Occupational rhinitis. Occupational asthma. Wood dust.
