Lung adenocarcinoma typically arises from the bronchial epithelium or bronchial glandular epithelium. A pathological picture of adenocarcinoma may display an acinar, papillary, micropapillary, lepidic, or solid growth, with either mucin or pneumocyte marker expression and it is usually located peripherally with pleural involvement. Their most frequent radiological pattern is ground glass pattern, solid nodules on chest CT scan. Primary lung cancer rarely presents as miliary mottling on chest x-ray. The miliary pattern shows numerous small nodules usually 1-3 mm in diameter in the lung with a sharp margin. The miliary pattern on chest radiography is usually found in disseminated tuberculosis, histoplasmosis, sarcoidosis, pneumoconiosis, bronchoalveolar carcinoma, or pulmonary siderosis. It can also be a sign of secondary metastasis to the lung from the thyroid, kidney. We report an unusual presentation of adenocarcinoma of lung presenting as bone marrow involvement.
