We present cytologic data from multiple samples from two cases of inverted sinonasal papilloma (ISP). These samples displayed the entire spectrum of squamous cell changes, including benign squamous papilloma, variable degrees of dysplasia, and invasive squamous cell carcinoma. In all instances, the cytologic impression coincided with the final diagnosis based on frozen and/or permanent histologic sections from the same samples. We suggest that cytologic examination be viewed as a useful initial approach in the diagnosis of ISP, and in the differential diagnosis of other tumors that occur in the same sites.

Chronic rhinosinusitis (CRS) is a common inflammatory disease of the paranasal sinuses with a yet unknown etiology. As studies continue to elucidate the disease's heterogeneity inflammatory profile and presentation, there is a growing interest in the influence of the nasal microbiome on disease pathogenesis and chronicity. The sinus microbiota appear dominated by the and genera; known upper airway pathogens, such as , are present in the upper airways of healthy individuals, though at relatively lower abundances than in CRS patients.

squamous cell carcinoma is a recently recognized entity characterized by a non-viral-related non-keratinizing squamous cell carcinoma with chromosomal rearrangement between on 6p22.3 and on Xq28. This neoplasm is associated with an aggressive clinical behavior, particularly regarding local recurrences and distant metastases even with its deceptively bland histomorphology.

Article Synopsis
- Sinonasal inverted papilloma (SNIP) has a high recurrence rate and the potential to become malignant, but its specific metabolic pathways and biomarkers are not fully understood.
- RNA sequencing identified significant gene alterations related to the estrogen biosynthesis pathway and highlighted five key biomarkers (AKR1B10, CYP1B1, CYP2C19, CYP3A5, and HSD17B13) that were correlated with SNIP pathogenesis.
- Functional analysis indicated that these biomarkers are involved in epithelial cell proliferation and EGFR signaling regulation, suggesting their potential as diagnostic and therapeutic targets for managing SNIP.

Background: Hyperostosis is a common radiographic feature of inverted papilloma (IP) tumor origin on computed tomography (CT). Herein, we developed a machine learning (ML) model capable of analyzing CT images and identifying IP attachment sites.
Methods: A retrospective review of patients treated for IP at our institution was performed.
