Basaloid squamous cell carcinoma (BSCC) is a rare subtype of squamous cell carcinoma. To date, only 95 cases of sinonasal BSCC have been reported in the English-language literature, and they account for 5% of all cases of head and neck BSCC. We describe what we believe is only the second reported case of a sinonasal tract BSCC that metastasized to the liver. The patient was a 36-year-old woman ...

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...

The nose and lungs have both histological and functional similarities and differences. Sinonasal and bronchial involvement are associated in many diseases. Cystic fibrosis, primary ciliary dyskinesia, Young's syndrome, and alpha-1 antitrypsin deficiency are diseases in which bronchiectasis and rhinosinusitis are both present. This review considers the diseases in which bronchiectasis occurs alo...

Abstract Sinonasal non-intestinal-type adenocarcinoma is a rare malignancy, with limited large-scale studies available in the medical literature. We present case report of 60-year-old male patient sinonasal adenocarcinoma, isolate lagophthalmos and abducens nerve palsy, who had been exposed for 30 years to hard wood dust.

BACKGROUND Sinonasal localization of Ewing's sarcoma in adults is an exceedingly rare event. METHODS The clinical records of 5 patients with primary sinonasal Ewing's sarcoma treated from 1992 to 2012 were retrospectively analyzed. All pathologic slides were reviewed by 2 experienced pathologists. All patients underwent multimodality treatments. RESULTS Median age was 36 years (range, 25-52...

BACKGROUND Most series about endoscopic resection of adenocarcinomas of the sinonasal tract present outcome data from a small heterogeneous group of patients with a relatively short follow-up period and a wide variety of histological subtypes and treatment protocols. This relatively large study with a very homogeneous study population updates our experience with a stable treatment protocol look...

OBJECTIVE The study purpose was to detect the value of magnetic resonance imaging (MRI) compared to computed tomography (CT) and different imaging modalities as conventional radiology in evaluation of sinonasal neoplasms diagnosed by Histopathology. METHODS Thirty patients (16 males and 14 females) were complaining of symptoms related to sinonasal tract. After thorough clinical and local exam...
