Skin lesions are common clinical phenomena in primary care, as well as emergency situations. Several studies have shown that every patient has an average of 1.7 visits to primary care physicians due to dermatological diseases. These visits can be related to seemingly mild diseases, such as contact dermatitis as the most common disorder in daily clinical practice, or potentially serious diseases, such as melanoma and metastasis. If a primary tumor is diagnosed, skin metastasis can be detected in 20% to 60% of patients. Cutaneous metastasis from lung tumor is not common; however, it can lead to a fatal prognosis with a median survival of 5.75 months. The purpose of this study was to highlight the importance of skin lesions as a diagnostic marker of serious disorders such as neoplasm. For this purpose, we conducted a review of skin metastasis and its relationship with different types of cancer, especially pulmonary cancer.
