Percutaneous transthoracic core needle biopsy has been advocated as a highly accurate technique for the diagnosis of anterior mediastinal masses.

At definitive surgical resection the tumour proved to be a B cell lymphoma. This case illustrates one ofthe important limitations ofneedle biopsy with its potential for sampling error.
