Tumor of the Nose - A Rare Manifestation of a Metastatic Lung Cancer.

Lung cancer most often metastasizes to the central nervous system, bone and liver. Although metastases to the skin are quite rare, it is estimated that they may be the first clinical manifestation of this disease in 0.7%-12% of cases. Metastases to the skin are caused by adenocarcinoma (about 30%), squamous cell carcinoma (30%) and undifferentiated carcinoma (40%). Nasal tip metastases are extremely rare. They can be confused with more common skin problems, including non-melanoma skin cancers, rhinophyma, inflammatory tumors or infectious diseases. We report two patients with a tumor on the nose, which proved to be the first sign of the metastatic lung cancer.
