Nasopharyngeal neoplasia is not common in horses. Tumours previously reported at this site include lymphosarcoma (Meschter and Allen, 1984; Lane, 1985), squamous cell carcinoma (Schuh, 1986) and undifferentiated adenocarcinoma (Baker, 1975). Equine mast cell tumours, both solitary and generalised, are usually confined to the skin and subcutis (Altera and Clark, 1970; Riley, Yovich and Howell, 1991).
Epistaxis has several well recognised causes including exercise induced pulmonary haemorrhage (Mason et al., 1983), progressive ethmoid haematoma (Cook and Littlewort, 1974; Boles, 1979; Haynes, 1984 and Greet, 1985) and guttural pouch mycosis (Cook et al., 1968). Less common causes include ulcerative rhinitis, nasal polyps and turbinate bone necrosis (Cook and Littlewort, 1974). Nasal and nasopharyngeal tumours form an unusual cause of epistaxis.
