“…The majority of the primary tracheal tumours are malignant (Pearson et al, 1984) and most of these are squamous and adenoid cystic carcinomas (Olmedo et al, 1982). Among the benign mesenchymal tumours the reported entities have included fibromas (Gilbert et al, 1953;MacLachlan, 1968), fibromyxoma (Pollak et al, 1985), fibrous histiocytoma (Sandstorm et al, 1978), granular cell tumour (Mikaelian etal., 1984), leiomyoma (Harris et al, 1967), and neurilemmoma (Horovitz etal., 1983). Paraganglioma (Liew etal., 1981), haemangiopericytoma (Ballard and Yarington, 1981) and hamartoma (Engelking, 1959) are also exceedingly rare lesions.…”
