Cutaneous metastasis as a presenting feature of adenocarcinoma of lung

Metastasis is a neoplastic lesion which arises from another neoplasm with which it is no longer in continuity. Cutaneous metastasis is the spread of malignant cells from a primary malignancy to the skin. Skin metastases occur in about 5.3% of patients with internal malignancies and represent 2% of all skin tumors. Breast cancer, in women, and lung cancer, in men, are the most common origins of cutaneous metastasis. It mostly occurs late in the course of disease. Herein, we report the case of a 97-year-old male who presented with asymptomatic, hyperpigmented, indurated plaques with crusting and few overlying tense bullae over the right side of the chest extending to the right axilla for 4 months. On evaluation, he was diagnosed as a case of metastatic adenocarcinoma, the primary being from the lung. He succumbed to his illness within 2 months of diagnosis
