Abstract：
This report presents a case of a rarely occurring inverted squamous papilloma, which shows papillary proliferation in squamous epithelium. Inverted papillomas (IPs) are benign epithelial growths that occur in the underlying stroma of the nasal cavity and paranasal sinuses. While viral infections, allergies, and chronic sinusitis have all been proposed as potential causes, the pathophysiology of this lesion is still unknown. Most of the time, IP reflects residual disease, yet the recurrence rates are extremely high. A 60-year-old male patient has chief complaints of right-sided nasal congestion and excessive sneezing and discharge from the nose, which cause discomfort to the patient and make him unable to sleep at night. Computed tomography reveals both the enlargement of the osteomeatal complex and soft-tissue density opacification of the right side of the nasal cavity. The only way to diagnose this type of squamous papilloma is through histopathological examination. In this work, we evaluated the histological characteristics of sinonasal IP and presented a case report of an uncommon instance of inverted squamous papilloma of the nasal cavity.
摘要：
本报告介绍了一例很少发生的内翻鳞状乳头状瘤，显示鳞状上皮的乳头状增生。内翻性乳头状瘤（IPs）是良性上皮生长，发生在鼻腔和鼻旁窦的下层基质中。而病毒感染,过敏,和慢性鼻窦炎都被认为是潜在的原因，该病变的病理生理学仍然未知。大多数时候,IP反映了残留疾病，然而复发率极高。一名60岁的男性患者主要抱怨右侧鼻塞和过度打喷嚏和从鼻子排出，这会给病人带来不适，使他晚上无法入睡。计算机断层扫描显示了鼻腔右侧的骨道复合体和软组织密度浑浊。诊断这种鳞状乳头状瘤的唯一方法是通过组织病理学检查。在这项工作中,我们评估了鼻窦IP的组织学特征，并提出了一例罕见的鼻腔倒置鳞状乳头状瘤的病例报告。
