Malignant tumours

Malignant tumours

The most common malignant tumours to occur within the nasal cavity and paranasal sinuses are squamous cell carcinomas ( Figure 51.57 ), adenoid cystic carcinomas and adenocarcinomas. Adenocarcinoma has been linked to exposure to hard wood dust in the furniture industry . Adenoid cystic carcinomas arise from minor salivary glands, which can be found in the nose. Suspicious signs of invasion of neighbouring tissues include diplopia, proptosis, loosening of the teeth ( Figure 51.58 ), trismus, CN palsies and regional lymphadenopathy . Figure 51.59 shows invasion of a left maxillar y antral carcinoma into adjacent structures, including the orbit, on an MRI scan. Patients with sinus or intranasal malignancy are best managed in a combined clinic where the expertise of ENT surgeons, maxillofacial surgeons and oncologists can be employed.
