It can be particularly puzzling for the reporting pathologists, when encountered unexpectedly in a tumour showing abrupt transition from the usual morphology to another unusual pattern. The literature reports a variety of combinations with carcinoma-to-carcinoma being the most common; and renal cell carcinomas appear to the most common recipient tumours with common donor tumours being breast, lung and renal cell carcinomas. The authors report a case of poorly-differentiated lung carcinoma metastasising into a carotid body paraganglioma. Our case is unique and in our knowledge the first described case of carotid body paraganglioma with metastasis from a lung primary. To the best of our knowledge this is the first report of this interesting biological phenomenon in this combination.<\/jats:p>","DOI":"10.1136\/bcr.01.2012.5517","type":"journal-article","created":{"date-parts":[[2012,4,4]],"date-time":"2012-04-04T16:39:50Z","timestamp":1333557590000},"page":"bcr0120125517","source":"Crossref","is-referenced-by-count":0,"title":["Metastasis
