Foreign body aspiration diagnosed by microscopy.
We report a rare case of foreign body aspiration diagnosed by microscopic analysis of a sample of the foreign body. A 50-year-old man presented with a 5-month history of 40 pound weight loss and a nonresolving right lower lobe pneumonia. Medical history, radiographic studies, direct visualization of the foreign body by flexible fiberoptic bronchoscopy, and gross examination of a sample of the foreign body retrieved by a forceps biopsy catheter failed to yield the diagnosis. Moderate bleeding associated with the bronchoscopic "biopsy" procedure contributed to a preliminary misdiagnosis of endobronchial tumor. Microscopic analysis of the "biopsy" specimen demonstrated vegetable matter. The patient underwent rigid bronchoscopy and a peanut was retrieved from the bronchus intermedius. He was maintained on antibiotics for an additional 8 weeks and had complete clinical and radiographic recovery. The epidemiology, presentation, and management strategies of foreign body aspiration in the adult are briefly reviewed.
