title: [Benign fibrous histiocytomas as a differential diagnosis in cavitary lung disease].
abstract: Benign fibrous histiocytomas (BFH) are uncommon pulmonary tumours. These lesions usually present as slow-growing, solid masses. We report the rare case of a young man with cavitary BFH. The 20-year-old patient, a non-invasive drug abuser, had suffered from hemoptysis for two months. The chest X-ray showed a solitary pulmonary nodule with a diameter of 2 cm in the left lower lobe with central cavitation. Fiberoptic bronchoscopy showed a normal bronchial system, biopsies were not diagnostic and no acid fast bacilli were found. Considering the patient's history and the cavitary process, a non-specific abscess was suspected and an antimicrobial treatment was started. Since no treatment effect was observed, biopsies from a second bronchoscopy were suspicious of a malignant mesenchymal tumour. Lower lobe resection with lymphadenectomy revealed a benign fibrous histiocytoma. This is--to our knowledge--the first reported case of a BFH presenting with cavitation.
