Published: December 1997

A 63-year old man presented with urinary frequency and urge. An IVU showed a tumour in the lower right ureter. Partial ureterectomy was done with a uretero-ureterostomy. Pathological investigation showed an inverted papilloma. Inverted papilloma of the ureter should always be considered in the differential diagnosis before major surgery is done. There is an association between inverted papilloma and urothelial carcinoma. Our patient developed an invasive bladder tumour 6 years after the operation on the inverted papilloma.

Inverted papilloma is a rare, benign epithelial tumor of the nasal and sinus cavities with an unclear etiology. It usually presents as unilateral nasal obstruction. Diagnosis is histological, and treatment is primarily surgical.

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.

Objective: Prior studies have been contradictory on the role of human papillomavirus (HPV) infection in sinonasal inverted papilloma (SNIP) recurrence. This systematic review and meta-analysis was performed to further evaluate this potential association.

Rationale And Objectives: Nasal polyps (NP) and inverted papilloma (IP) are benign tumors within the nasal cavity, each necessitating distinct treatment approaches. Herein, we investigate the utility of a deep learning (DL) model for distinguishing between NP and IP.

Materials And Methods: A total of 1791 patients with nasal benign tumors from two hospitals were retrospectively enrolled.
