Introduction: We report a case of occupational hypersensitivity pneumonitis in a patient handling chicory leaves.
Case report: The diagnosis was based symptoms of broncho-alveolitis with pyrexia, positive precipitins to moulds present on chicory, especially Fusarium, and the disappearance of the clinical and radiological manifestations following cessation of exposure to chicory.
Conclusion: "Chicory worker's lung" is an occupational disease which should be considered in cases of respiratory symptoms suggestive of hypersensitivity pneumonitis and chronic exposure to chicory leaves.
