[Neuroendocrine carcinoma of the nasal fossa. An independent entity?].

We present one case of a neuroendocrine carcinoma of nasal fossa and paranasal sinuses, of aggressive behavior, which has been controlled with chemo-radiotherapy after a double postsurgical recurrence. We do a literature revision emphasizing the anatomopathologic differentiation of these tumors with the olfactory neuroblastomas, and the therapeutic controversies in advanced stages.
