[Bronchiolitis obliterans with secondary pneumoconiosis]

A seven year old girl developed recurrent bronchitis since three month of life. Chronic wheezing remain between exacerbations. Pathological examination of her lung biopsy disclosed bronchiolar obstruction due to peribronchiolar fibroses. Storage of anthracoid material, compatible with pneumoconiosis in relation to impairment on mucociliary function, was present. This is an unusual picture in childhood.
