@entity1358 manifesting with @entity1415 in a XXXX : a case report.

@entity1 @entity548 @entity1415 @entity1358 @entity3 @entity703
INTRODUCTION: @entity3 in the sinonasal region occurs rarely and the primary site may be elusive. This case highlights the possibility of an occult @entity703 manifesting with nasal symptoms and the risk of severe @entity548 following nasal biopsy. CASE PRESENTATION: We report the case of a 79-year-old Caucasian @entity1 who presented with a six-week history of intermittent left-sided nosebleeds. She was fit, without previous surgery or anticoagulation. Nasal endoscopy and computed tomography showed a hemorrhagic mass occupying her left ethmoid cells and middle meatus. After a highly hemorrhagic biopsy, the lesion was histologically confirmed as @entity1358 . Screening revealed a right kidney mass with widespread metastases. Palliative radiotherapy to the sinonasal metastasis and systemic treatment rendered her free of symptoms nine months after initial presentation. CONCLUSIONS: General practitioners and ear, nose and throat (ENT) doctors are very often confronted with @entity1415 . A small minority of @entity1 with @entity1415 show a primary or metastatic nasal mass. Detection of the origin of secondary sinonasal masses requires a high index of suspicion and examination of infraclavicular sites by a multidisciplinary team. @entity1358 metastases are prone to severe @entity548 during any surgical intervention, therefore, preoperative embolization is recommended. Resection or radiotherapy to the sinonasal metastasis of renal origin is justified in order to prevent recurrent nosebleeds.
