Skin metastasis

Skin is one of the common metastatic sites of various malignant tumors. Metastatic skin cancer can occur in any age group, but most occur in the age of 40 to 70. Chest wall, armpits and abdomen are the most common sites of skin metastatic cancer. The onset of primary lung cancer is hidden, especially peripheral lung cancer, which often lacks typical respiratory symptoms, and is often delayed in diagnosis. Sometimes subcutaneous metastases may be the only feature of lung cancer.
