Abstract
The term thymoma, formerly used to designate a large variety of histologically unrelated tumours involving the thymus, is now restricted to neoplasms arising from — or differentiating towards — thymic epithelial cells, regardless of the presence and relative number of nonneoplastic lymphocytes. Although in a generic sense all thymic epithelial neoplasms could be designated as thymomas, it has been customary to restrict this term to those neoplasms showing no overt atypia of the epithelial component, and to classify the others as thymic carcinomas (see Sect. l.2)
