The oral cavity is the most frequent location but it is also reported in the larynx, pyriform sinus, nasal cavity, external auditory meatus, esophagus, genitals, uterine cervix and skin. In the oral cavity, it is more common on the buccal and alveolar mucosae, than on the tongue, lip and palate.1 The pathogenesis of oral cavity verrucous carcinoma is uncertain. Some studies report the association with chronic use of inhaled or chewable tobacco, alcohol and a potential role of human papillomavirus infection, particularly through downregulation of oncosuppressor genes.2

The main predisposing factors are neck dissection, radiation therapy, local infection, tissue necrosis, vascular exposure and pharyngocutaneous fistula. Materials and Methods: The authors present a clinical case and bibliographic review contemplating the predisposing factors, clinical presentation, treatment and prognosis of this entity. The rupture of the carotid artery was observed on a patient with retromolar trigone carcinoma, exposed to radiation therapy and after surgical treatment Results: Bleeding was controlled with carotid ligation. Other solutions for preservation of carotid lumen were considered inappropriate or unavailable. In spite of the expected high rate of cerebrovascular events, there were no neurological deficits observed in the postoperative period. Conclusion: Because of its severity, the carotid blowout syndrome must be considered in pa...

Os Profissionais de Saúde devem estar preparados para uma correcta e atempada resolução destes casos. Os autores apresentam uma revisão bibliográfica sobre lesões por arma de fogo em Otorrinolaringologia (ORL), do diagnóstico à terapêutica, a propósito de vários casos observados no Serviço de Urgência ORL do Hospital Garcia de Orta. Os autores pretendem salientar a necessidade do Otorrinolaringologista estar familiarizado com os procedimentos a ter nestes doentes, pois as lesões na face e pescoço podem condicionar elevada morbilidade e mesmo mortalidade, na medida em que existem múltiplas estruturas vitais nestas áreas anatómicas.
