title: [Epistaxis as initial manifestation of disseminated renal adenocarcinoma].
abstract: Peculiar renal carcinoma tendency to unusual distant metastases suggest this primary neoplasm to be accounted in differential diagnosis of metastases as first clinical symptom of cancer. Renal cell carcinoma present metastases in 26-30% of cases at the time of diagnosis. Head and neck metastases from renal carcinoma are said to be present in 8% (6-15.2%) of patients, and half of them are asented on paranasal sinuses. We report a 70-years-old patient with recurrent epistaxis as first clinical sign of a nasosinusal metastases from renal disseminated carcinoma, who precised selective embolization. Epidemyologic, diagnostic and therapeutical aspects are briefly reviewed in literature. Nasosinusal metastases are uncommon in clinical practice. We emphasized the need of primary tumor investigation in the organs most often responsible for these metastasic deposits as: kidney (50%), lungs, breast, gastrointestinal tract, urogenital ridge and thyroid gland. Individualized treatment depends on leasions number and localization. On routine follow up of hipernephroma nephrectomized patients a high suspect index has to be considered as paranasal metastases can eventually occur.
