Cutaneous metastases as the presenting feature of lung cancer

Lung cancer is the second most common cancer diagnosed in men and women worldwide with the highest mortality. A rare site of metastases for lung cancer is the skin. Typically, the diagnosis is secure prior to developing cutaneous metastases. We present a case of a man in his mid-70s who presented to dermatology with cutaneous metastases. We outline the presentation, diagnostic workup and management of this case. We also review the literature of cutaneous metastases in lung cancer; highlighting the clinical need for a timely accurate diagnosis and the implication in terms of prognosis.
