title: [Tracheo-bronchial granular cell tumors. Apropos of 4 cases].
abstract: We have seen four cases of granular cell tumor (Abrikossoff's tumour) and it is recalled that these tumours are most often discovered fortuitously by bronchoscopy in the tracheo-bronchial region because they have a non specific clinical presentation. The cytological and histological characteristics enable an accurate diagnosis but there are problems posed as to the histogenesis of these tumours. With a tumour with a slow progression regular surveillance with regular biopsies seems preferable as in certain cases the tumour regresses spontaneously or disappears after ablation with the forceps. A good alternative approach is destruction of the tumours with a laser in certain complicated forms which enables one to avoid surgical excision.
