The aim of this article is to review, discuss, and illustrate the role of endoscopy in the management of nasal neoplasia. We have reviewed our own experience and illustrate this with four cases. We discuss the role of endoscopy in the diagnosis, biopsy, resection, posttherapeutic surveillance, and palliation of these tumors. Tumours of the nasal septum are rare. They mostly concern squamous cell carcinomas.
Verrucous carcinomas are exceptional, with only three well-documented cases in the literature.
We operated such a tumour, localized both on the columella and nasal septum. The difference in clonal selection among the L1-L3 lines further shows that genetic convergence during in vitro growth in stable conditions is dependent not only on the clones' ability to adapt to the culture conditions, but also on the nature of the neighboring cells with which they collaborate and compete.
