Sinonasal undifferentiated carcinoma is a rare and aggressive type of cancer originating in the epithelial layer of the nasal cavity or paranasal sinuses. It was first diagnosed in 1987. The aggressive nature of the cancer coupled with the advanced stage of disease upon presentation lead to a poor survival rate.
Biphenotypic sinonasal sarcoma is a newly recognized, very rare, low-grade malignant tumor of the nasal cavity, which was formerly probably included in fibrosarcoma and synovial sarcoma cases. It was incorporated into the fourth edition of the World Health Organization Classification of Head and Neck Tumours , published in 2017.
Globally, head and neck cancer accounts for 650,000 new cases of cancer and 330,000 deaths annually on average. In 2018, it was the seventh most common cancer worldwide, with 890,000 new cases documented and 450,000 people dying from the disease. [12] The risk of developing head and neck cancer increases with age, especially after 50 years.

NUT carcinoma (NC; formerly NUT midline carcinoma (NMC)) is a rare genetically defined, very aggressive squamous cell epithelial cancer that usually arises in the midline of the body and is characterized by a chromosomal rearrangement in the nuclear protein in testis gene (i.e. NUTM1 gene). [2]
Esthesioneuroblastoma can resemble small blue cell tumors like squamous cell carcinoma, sinonasal undifferentiated carcinoma, extranodal NK/T cell lymphoma, nasal type, rhabdomyosarcoma, Ewing/PNET, mucosal malignant melanoma and neuroendocrine carcinomas (NEC) that occur in the intranasal tract.
