Inverted papilloma (IP) is a common proliferation of squamous epithelial cells of the sinonasal tract. Although considered benign, IP is known to cause local destruction, has a high rate of recurrence, and a low, but significant rate of malignant transformation. Differentiating an IP from its histologic mimickers is essential for appropriate risk stratification and long-term surveillance. A classic case of sinonasal inverted papilloma is discussed.
内翻性乳头状瘤(IP)是鼻腔鼻窦通道鳞状上皮细胞的常见增生。虽然被认为是良性的,但 IP 已知会引起局部破坏,复发率高,恶性转化率虽然低,但显著。将 IP 与其组织学模拟物区分开来对于适当的风险分层和长期监测至关重要。讨论了一个经典的鼻腔鼻窦内翻性乳头状瘤病例。
