Indian Journal of Pathology & Microbiology. 1993 Apr; 36(2): 133-7http://imsear.searo.who.int/handle/123456789/74383Although thymomas are the commonest neoplasms of the anterior mediastinum, distinction between benign and malignant thymomas is controversial on Fine needle aspiration biopsy. We present cytomorphological features of a case of invasive thymoma on computed tomographic guided fine needle aspiration cytology and its basis is discussed in light of current concepts of thymic tumours.engBiopsy, NeedleHumansMaleMiddle AgedThymoma --diagnosisThymus Neoplasms --diagnosisCase Reports
