ABSTRACT
Developing in a limited space, rare tumors located at the nose and paranasal sinuses are sometimes difficult to diagnose due to their modest clinical presentation, which is uncorrelated with anatomopathological diversity. This limits the preoperative diagnosis without added immune histochemical study; for that reason, we present our experience with these tumors with the intention of raising awareness. The patient included in our study was investigated by our department through clinical and endoscopic examination, imaging investigations, and an anatomic-pathological study. The selected patient gave consent for participation and inclusion in this research study in compliance with the 1964 Declaration of Helsinki.

We report on an unusual case of laterocervical bilateral metastatatic masses with unknown clinical, radiological or computer tomographicic detected primary site of origin. Cancer of an unknown primary site is a clinical syndrome, accounting for 2%-5% of patients with cancer. The peculiarities of our case are its evolution as fast-growing bilateral tumor masses with involvement of other neck structures and its unexpected origin from the lung, certified by complementary immunohistochemical tests following surgery, in the absence of any other clinical signs or any detectable lung tumor mass by radiological or computer tomographic tests.
