Occupational asthma due to exposure to African cherry (Makore) wood dust

Abstract

A 35-year-old man who had been a carpenter and a cabinet worker for over 15 years, was referred to our clinic with a 4-month history of cough, chest tightness and difficulty in breathing which occurred within minutes of exposure to African cherry wood (Makore). He developed a dual asthmatic reaction on specific challenge test with an extract of African cherry wood dust. Thus, the diagnosis of occupational asthma due to exposure to African cherry wood dust was confirmed by the specific challenge test. The mechanism of asthma due to African cherry wood dust exposure is not clear.
