PURPOSE OF REVIEW: Sinonasal mucosal melanoma (SNMM) is an aggressive cancer with a poor prognosis. Although there is significant study surrounding the treatment of sinonasal malignancies and cutaneous melanomas, the rarity of this tumor has largely precluded robust outcomes analyses. The authors of this review seek to provide an overview of the recent literature related to the treatment of SNMM with added context from our institutional experience with this disease. RECENT FINDINGS: In the surgical management of sinonasal malignancies and SNMM specifically, resection via endoscopic endonasal technique appears to offer comparable oncologic outcomes versus an open approach...

Nuclear protein in testis (NUT) carcinoma is a rare malignant neoplasm with an undifferentiated morphology. Its diagnosis is often difficult, especially as the sinonasal tract gives rise to many tumors with undifferentiated morphologies. Not many cases of sinonasal NUT carcinomas have been reported, and its clinicopathological features have not been sufficiently clarified. In this study, we performed a clinicopathological study of 4 patients with sinonasal NUT carcinoma, including wide-ranging immunohistochemical tests and cytogenetic analyses using fluorescence in situ hybridization and DNA sequencing...

INTRODUCTION: Inverted papillomas (IP) are benign sinonasal neoplasms, which account for 0.5-4% of all nasal tumors. IPs have been known to transform into squamous cell carcinoma in 5-15% of cases. Rarely, transformations to other malignancies have been reported. Here we report a unique case of malignant transformation of an IP into sinonasal undifferentiated carcinoma (SNUC). METHODS: A case report with a literature review; institutional review board exempted. The clinical presentation, radiographic features, surgical intervention, histopathologic analysis, treatment, and outcome of the case were examined...

BACKGROUND: Squamous cell carcinoma (SCC) is the most common malignancy in the sinonasal tract. We present the first population-based analysis that examines geographic differences in demographic and clinical characteristics, socioeconomic factors, treatment modality, and disease-specific survival (DSS) of this entity. METHODS: All cases of sinonasal squamous cell carcinoma (SNSCC) were queried using the U.S. Surveillance, Epidemiology, and End Results (SEER) registry from 1973 to 2013...

Importance: Sinonasal mucosal melanoma (SMM) is a rare malignant neoplasm characterized by a poor prognosis despite aggressive intervention including wide surgical resection. Margin status has previously been cited as an important prognostic factor for local control and overall survival (OS) in patients who undergo either an open or endoscopic surgical approach. No comparisons have been made, however, in patients who have undergone gross total resection with or without positive margins...

Inverted papilloma of the nasal cavity is a benign neoplasm, although it can be locally invasive and has the potential for malignant degeneration. Inverted papilloma of the temporal bone is extremely rare. We describe a case of a 44-year-old woman who was treated for nasal inverted papilloma and was later found to have inverted papilloma of her temporal bone. The patient required several procedures to remove the inverted papilloma from the nasal cavity and temporal bone, and she is currently free of recurrence...

NUT midline carcinomas (NMCs) are rare, poorly differentiated tumors with aggressive biological behavior and a characteristic molecular signature. Availability of NUT antibody has facilitated diagnosis of NMC without molecular testing. We report a series of head and neck NMCs diagnosed using NUT IHC at our institute, including one case with an unusual course. Immunohistochemistry for NUT was performed in nasal and sinonasal tumors with diagnoses of undifferentiated carcinoma, poorly differentiated squamous cell carcinoma and malignant neoplasm, not otherwise specified, to identify cases of NMC...

Patients may face functional, aesthetic, and social distress because of the palatal defects. Prosthetic rehabilitation of maxillectomy or developmental defect can be challenging for prosthodontists. Prognosis of the prosthetic appliances can be affected not only by patients' own ability to adapt to the prosthesis but also by the factors like the remaining teeth, bony structure, and existing mucosa. Maxillary defects are usually developed by surgical intercession of the benign or malignant conditions and trauma cases...

Primary sinonasal melanoma is a rare disease. We present a case of melanoma in sinuses without abnormal F-FDG activity anywhere in the scanned portion of the body. In further assessment, C-choline PET/CT revealed high activity in the paranasal sinuses, skull base, and adjacent brain, in agreement with the high signal on contrast-enhanced T1-weighted MRI scan, which suggested the residual tumor.

The management of sinonasal cancer is a challenge due to its low occurrence and anatomical and significant diversity of histological types. The therapeutic modality used should be tailored individually according to the histology, tumour stage, molecular profile and previous treatments. The clinical management of sinonasal cancer has improved greatly owing to developments in endoscopic surgery and precision radiotherapy. Complete surgical resection is the mainstay of sinonasal malignancies' management but multimodality therapy is associated with improved outcomes in certain histologies...

REVIEW
P Blanchard, S J Frank
The absence of exit dose and the sharp lateral penumbra are key assets for proton therapy, which are responsible for its dosimetric superiority over advanced photon radiotherapy. Dosimetric comparisons have consistently shown a reduction of the integral dose and the dose to organs at risk favouring intensity-modulated proton therapy (IMPT) over intensity-modulated radiotherapy (IMRT). The structures that benefit the most of these dosimetric improvements in head and neck cancers are the anterior oral cavity, the posterior fossa, the visual apparatus and swallowing structures...

Sinonasal undifferentiated carcinoma (SNUC) is a rare malignancy of the upper airways and anterior skull base that carries a poor prognosis. The tumor is known to be invasive into the surrounding structures of the skull base and brain. To date, there is only one existing case report documenting drop metastasis to the intradural extramedullary spinal cord. To the best of our knowledge, we present the second case of metastatic SNUC to the spine. This report describes a 59-year-old male with a history of head and neck SNUC who presented with thoracic back pain and bilateral lower extremity paresis...
