However, about 60% of mucosal melanomas arise in the upper aerodigestive tract, with sinonasal
tract accounting for 66%, oral cavity about 25%, and the remaining in the nasopharynx, oropharynx, and larynx; mucosal melanoma represents about 4% of all sinonasal
To study the sinonasal
anatomical variations and their prevalence in patients with chronic rhinosinusitis with the help of computerized tomography.
Renal cell carcinoma (RCC) metastatic in the sinonasal
cavity is rare.
tuberculosis is rarely encountered even in developing and endemic countries, and it is usually secondary to pre-existing foci elsewhere in the body.
It was first described in the sinonasal
region by Chowdhuri and his colleagues in 19651 and later in 1972 Oloffson et al.2 reported a laryngeal SCNEC.
Cancers involving the sinonasal
region are fairly uncommon representing approximately 0.2% to 1% of all cancers and 3% to 5% of all upper airway malignancies , exhibiting diverse histological subtypes, biology, and therapeutic response.
Carcinosarcoma may arise from any squamous epithelium (e.g., salivary glands, respiratory tract, upper aerodigestive tract, and female reproductive organs) , but its occurrence in the sinonasal
region is extremely rare .
tract is affected by a diverse spectrum of neoplasms, which may be epithelial, mesenchymal, or neuroectodermal in origin .

To settle the long-standing battle on the nomenclature of NP, the WHO in 1991 has given directive that any NP encountered in the sinonasal
area should be labeled depending upon the histopathology under three headings: (i) IP, (ii) EP, and (iii) oncocytic papilloma.
Aims: To assess the rate of C-KIT positivity and its effect on survival of surgically treated sinonasal
malignant melanoma patients with other histopathological biomarkers and clinical features.
