MMP11 as a Prognostic Indicator for Inverted Papilloma Histologic Grade and Recurrence. [PDF]

Laryngoscope
Matrix metalloproteinase‐11 (MMP11) expression increases with inverted papilloma (IP) histologic grade and is significantly higher in patients who develop recurrence. Quantitative immunohistochemistry revealed that elevated MMP11 predicts both increased recurrence risk and shorter time to recurrence, independent of dysplasia.

Multimodal management of PD-L1 positive sinonasal inverted papilloma with malignant transformation. [PDF]

World J Otorhinolaryngol Head Neck Surg
Abstract Inverted papillomas (IP) are rare sinonasal tumors (Schneiderian papillomas) characterized by local invasion, with high recurrence rates and potential for malignant transformation into squamous cell carcinoma (SCC ex‐IP). Traditionally, the mainstay of treatment has been surgical resection, often challenging due to invasion of the skull base ...
