title: [Diagnostic image (4)(Bronchoalveolar lavage fluid)].
abstract: Two apparently healthy male volunteers, 28 and 32 years old, were examined before participation in a drug trial. Bronchial fluid was obtained. The lavage fluid from the second volunteer who had smoked 20 cigarettes a day for the past 16 years showed marked brownish discolouration, as compared to the transparent fluid of the non smoking first volunteer.
