The Differential Diagnosis of Sinonasal/Nasopharyngeal Neuroendocrine/Neuroectodermally Derived Tumors

Olfactory neuroblastoma (ONB) is a malignant neoplasm thought to arise from the olfactory membrane of the sinonasal tract.

The second opinion was that the specimens represented an invasive, poorly differentiated NEC, probably a large-cell variant, with the differential diagnosis lying at a point somewhere between poorly differentiated large-cell NEC and high-grade olfactory neuroblastoma.
