Margin status is a major predictor of the patient´s outcome, histologically free margins of ≥ 5 mm are demanded.

Kaplan-Meier analysis revealed no significant differences for OS or DFS if R0-status was achieved by initial resection or immediate re-resection.

Among them, neuroendocrine and undifferentiated tumors are rare but noteworthy, because of their distinctive features, aggressive nature, and diagnostic complexities. A literature search was conducted in the PubMed/MEDLINE and the Scopus databases from 2019 until inception. The keywords \"neuroendocrine\", \"undifferentiated\", \"nose\", \"sinonasal\", \"paranasal\", \"skull base\" were used. Thirty-eight articles referring to neuroendocrine and undifferentiated tumors of the nose, paranasal sinuses and the skull base were finally included and analyzed. Neuroendocrine and undifferentiated tumors of the nose, paranasal sinuses and the skull base are infrequent malignancies, most commonly affecting middle-aged men. They usually present with non-specific symptoms, even though ocular or neurologic manifestations may occur. Prognosis is generally poor; however, novel targeted and immunological therapies have shown promising results. Sinonasal Neuroendocrine Carcinomas (SNECs) carry distinct histological and immunohistochemical features. Management consists of surgical resection coupled with systematic therapy. Sinonasal Undifferentiated Carcinomas (SNUCs) lack specific squamous or glandular features. They typically stain positive for pancytokeratin and INI1 antibody. Treatment includes induction chemotherapy, followed by a combination of chemotherapy and radiotherapy. Olfactory neuroblastomas (ONBs) have neuroepithelial or neuroblastic features. They show diffuse positivity for various markers, including synaptophysin, chromogranin, and neuron-specific enolase (NSE). Surgical resection plus radiotherapy is considered the treatment of choice. In conclusion, neuroendocrine and undifferentiated tumors arising from the nose, paranasal sinuses and the skull base represent a unique group of malignancies. A thorough understanding of their clinical features, molecular changes, diagnostic approaches, treatment modalities, and prognostic factors is critical for providing optimal patient care.
