Adenocarcinoma of the Lung with Unusual Widespread Contralateral Lung Metastases in a Young Nonsmoker

Abstract

Lung cancer is a fairly common malignancy, after breast cancer in women and prostate cancer in males. Most cases of cancer of the lung occur in older patients with a history of tobacco use or other risk factor(s). It rarely occurs in patients under 25 years of age. Female patients with family history appear to develop lung cancer at an earlier age. In patients with extensive disease, intrathoracic metastases often spread to the mediastinum, ipsilateral pleura, body thoracic skeletal, and the ipsilateral lung. However, contralateral lungs metastasis is a very rare finding. This case report involved a 23‑year‑old male, nonsmoker that presented adenocarcinoma of the lung with an unusual widespread contralateral metastasis.
