Abstract
An 87-year-old Japanese man, who had suffered from pneumoconiosis because he worked for over 25 years as a coal miner, visited the hospital with the chief complaint of dullness of chest and back. Chest X-ray revealed bilateral abnormal multiple nodules and calcification of hilar nodes. The fine needle aspiration biopsy cytology from the right supraclavicular lymph node revealed black fine carbon granules. silic acid salts and carbon-laden macrophages. These findings showed silicoanthracosis of the lymph node. We must be aware that cervical lymph node swelling can indicate not only carcinoma metastasis and tuberculosis but also nodal involvement of pneumoconiosis.
