RATIONALE Sinonasal inverted papilloma (IP) is a locally aggressive tumor found in the schneiderian membrane, lining the nasal cavity and paranasal sinuses. PATIENT CONCERNS We report a case of a 63-year-old woman with undifferentiated carcinoma (UC) arising in an IP in the left maxillary sinus. DIAGNOSES The preoperative diagnosis was IP of the maxillary sinus. INTERVENTIONS We performed...

introduction: plasmacytoma is a monoclonal proliferation of plasma cells. it can be an isolated lesion, for which the term extramedullary plasmacytoma is used, or a representation of multiple myeloma.the upper respiratory tract is the most common site for an extramedullary plasmacytoma. sinonasal plasmacytomas cause different symptoms depending on the sites of origins and the areas of involveme...

OBJECTIVE Sinonasal adenocarcinoma is a tumor typically associated with exposure to occupational carcinogens. The International Agency for Research on Cancer (IARC) published several data in order to classify carcinogenic power of physical-chemical agents as far as sinonasal cancer is concerned. MATERIALS AND METHODS We report a clinical case of sinonasal adenocarcinoma observed in an 84 year...

BACKGROUND A rare head and neck disease that may benefit from definitive or palliative stereotactic body radiation therapy (SBRT) is sinonasal malignant melanoma. These tumors can be very aggressive and often lead to severe epistaxis and significant mass effect. Results from only a handful of head and neck sinonasal malignant melanoma treated with SBRT are available in the current literature. ...

Sinonasal intestinal-type adenocarcinomas (ITAC) are very uncommon, with an overall incidence of <1 case per 1 million person-years and prevalent among people who work for prolonged periods in wood or leather industries. Here, we present a rare sinonasal adenocarcinoma 38yr old male.

sinonasal teratocarcinosarcoma (sntcs) is a rare tumor characterized by mixture architecture of epithelial and mesenchymal components. sntcs is a highly malignant tumor displaying progressive and aggressive growth with poor prognosis. only about 40% of all patients survive after five years. it seems the combination of surgery and radiotherapy currently is the most effective treatment. in this r...

In this review, we demonstrate that patients with chronic obstructive pulmonary disease (COPD) frequently report sinonasal symptoms. Furthermore, we present evidence that smoking on its own can cause nasal disease and that, in COPD patients, nasal inflammation mimics that of the bronchi. All this evidence suggests that COPD-related sinonasal disease does exist and that smoking on its own rather...

Introduction: Sinonasal malignancies are uncommon neoplasms with several histological subtypes. These malignancies have a poor prognosis and, because of the nonspecific nature of the symptoms, most patients are diagnosed late when the disease is already at an advanced stage. Therefore, most sinonasal malignancies tend to be treated with surgery and postoperative radiotherapy. Understanding the ...
