Recurrent Small Cell Carcinoma of the Lung With Cutaneous Metastasis in Breast.

Lung cancer remains the leading cause of cancer-related deaths and the second leading cause of new cancer cases in the United States. Although more commonly involving hilar nodes, the liver, adrenal glands, bones, and the brain, lung cancer can metastasize to almost any organ. Metastases, although rare in the skin may be the first sign of a lung cancer or cutaneous metastases may present as a sign of recurrent disease.
