Skin metastases are rarely found in lung cancer compared to other types of neoplasia. Of the types of lung cancer that can have skin metastases, the most common one is adenocarcinoma. Pulmonary cancer metastasizing to the skin has poor prognosis, usually the survival rate of the patients is 4-6 months. We present the case of a 59-year-old woman, smoker, high blood pressure, dyslipidemia, with two skin ertitemato-nodular lesions, incompletely delimited, with a diameter of 4-5cm, in the left arm (1/3 medio-external) and left latero-thoracic (near IV intercostal space) area, discovered during a regular medical examination at her family doctor's practice. After multiple clinical and paraclinical investigations, almost 3 months after the initial presentation, the patient was diagnosed with stage IV pulmonary adenocarcinoma with supra and subdiaphragmatic lymph-node metastases, soft tissue metastases, liver metastases and breast metastases. Oncological treatment was initiated, but the patient's progression was unfavorable, her passing occurring 6 months after being diagnosed.
