Abstract
Here we present a case of a 75-year-old man with an incidentally discovered anterior mediastinal mass, which on resection showed histologic features of both type A and micronodular thymoma with lymphoid stroma (MNT). MNT is a rare variant of thymoma with a characteristic appearance of distinct nodules of epithelial cells with few interspersed lymphocytes surrounded by abundant lymphoid stroma that lacks epithelial cells. We discuss features of this tumor and compare similar cases reported in the literature.
