Nadir olgulardan; Sinonazal onkositik papillom

Abstract

Sinonazal papillomlar benign epitelyal neoplaziler olup nadir görülürler. Sinonazal onkositik papillom (SOP), diğer adı ile Schneiderian papillomu ise tüm sinonazal papillomların en nadir görülen histolojik alt tipidir. Biz bu olgumuzda, sol maksiller sinüs tabanında hipermetabolik duvar kalınlaşma saptanan ‘’Sinonazal Onkositik Papillom’’ tanısı almış 62 yaşındaki erkek hastayı sunduk.

Sinonasal papillomas are rare benign epithelial neoplasms. There are three histopathological subtypes. Sinonasal oncocytic papilloma (SOP), also known as Schneiderian papilloma, is the rarest histological subtype of all sinonasal papillomas. It is usually seen unilaterally and the most common location is the maxillary sinus, but much less frequently it can be localized in the ethmoid and sphenoid sinuses. The malignant transformation rate is low in SOP, the most common malignancy is squamous cell carcinoma. It is very important to sample the entire material to detect the focus of malignant transformation. In this case, we present a 62-year-old male patient diagnosed "Sinonasal Oncocytic Papilloma” with hypermetabolic wall thickening in left maxillary sinüs.
