title: A silicosis patient presenting with an enlarged supraclavicular lymph node.
abstract: A stone splitter was discovered to have an enlarged supraclavicular lymph node which showed nodules with bi-refringent crystals on histological examination. He had worked in a dusty environment for more than 10 years with ineffective respiratory protection. He gave a history of occasional cough with blood-stained sputum for 10 years for which no definite diagnosis was made. Silicosis (classified as type s/s with profusion 1/1) was confirmed after his chest radiographs were reviewed. The presentation was unusual and illustrated the importance of an occupational history in clinical practice.
