Lung cancer is often metastasized to the brain, liver, kidneys, bone, bone marrow, and adrenal glands; however, metastasis of primary lung cancer to the paranasal sinuses is extremely rare.
In this paper, we present a case of metastatic tumors of the sinus secondary to lung adenocarcinoma. The patient was a 46-year-old woman who underwent surgical removal of lung carcinoma. Four months after the surgical removal of the lung tumor, the patient presented with epistaxis, and on investigation, the diagnosis was confirmed to be nasal sinus tumors due to metastasis of lung adenocarcinoma.
Thorough investigation of patients with epistaxis and a history of lung cancer is necessary to diagnose metastatic sinus tumors. We reviewed relevant literature and found that there are no characteristic clinical or radiologic features for metastatic sinus tumors; however, the diagnosis can be confirmed by histopathological examination of biopsied tumor sample.
Core Tip: Lung adenocarcinoma metastasis restricted to the paranasal sinus is a rare phenomenon. In this report, we present a rare case of metastatic tumors of the sinus secondary to lung adenocarcinoma. After lung cancer surgery, the patient had no postoperative complications and was completely asymptomatic at the second-year postoperative follow-up. We reviewed relevant literature in order to identify the characteristic features observed in cases of sinus metastasis of lung adenocarcinoma.
