PURPOSE OF REVIEW Sinonasal undifferentiated carcinoma is a rare and extremely malignant tumor of the paranasal sinuses. Historically, treatment outcomes have been poor. This review presents recent data on the management of sinonasal undifferentiated carcinoma and examines treatment trends that may result in improved locoregional control and survival. RECENT FINDINGS Patients who receive aggr...
BACKGROUND Sinonasal angiomatous polyp (SAP) is a rare subtype of sinonasal polyp that might be misdiagnosed as a malignant lesion due to its clinical symptoms. METHODS We retrospectively enrolled the patients who were diagnosed with SAP in our hospital during 2008-2015. We analyzed the clinical symptoms, radiological findings, and pathological features of all patients diagnosed with SAP. R...

hemangiomas of the sinonasal tract are rare, and because these lesions lack the typical signs or symptoms, they can be confused with other malignant conditions. we report a case of cavernous hemangioma of the maxillary sinus in a 68-year-old man that was completely resected by endoscopic sinus surgery. although computed tomography (ct) and magnetic resonance imaging (mri) showed several enhanci...
Primary non-Hodgkin’s lymphomas (NHL) of the sinonasal tract are rather uncommon entities. Morphologically and radiographically, sinonasal lymphomas are difficult to distinguish from other malignant neoplasms or nonneoplastic processes. They have a variable presentation from fulminant destructive manifestations to chronic indolent type of disease and may mimic as carcinomas and invasive fungal ...
OBJECTIVES/HYPOTHESIS Assessment of patients with sinonasal malignancy is challenging due to the low disease incidence and diverse histopathology. The current literature is composed mainly of retrospective studies with heterogeneous cohorts, and the rarity of cases limits our understanding of disease characteristics and treatment outcomes. We describe the development of a prospective, multi-ins...
Maxillary sinus mucocele can occur due to many medical factors such as chronic infection, allergic sinonasal disease, trauma, and previous surgery. However, it occurs mainly after Caldwell-Luc operation, usually more than 10 years after surgery. There are a few cases of maxillary sinus mucocele with ocular symptoms. Also, a case causing ocular symptoms because of invasion to the orbital floor i...
Changes in imaging sinonasal inflammatory disease have paralleled changes in the treatment of chronic sinusitis. As functional endoscopic sinus surgery has become a more widespread technique, coronal computed tomography (CT) has become the primary imaging modality, replacing plain radiography. Knowledge of the plethora of sinonasal anatomic variations and the inherent surgical implications is c...
