A CT scan revealed a 42-mm, well-defined, enhancing mass, including a partial low-density area in front of the left-sided tracheal bifurcation (Fig. 2A), and extremely low bone mineral density (Fig. 2B). 99m Tc-methoxy-isobutyl-isonitrile (MIBI) scintigraphy showed an accumulation in the mediastinum in both the early and the late phases.
The tumor is well-circumscribed, but there are no capsules and only a few small nodules (arrow) in the surrounding adipose tissue (hematoxylin and eosin, x5). (A) Tumor cells consisting mainly of chief cells and some oxyphil cells. No necrotic areas or nuclear atypia present and only a few mitotic figures (hematoxylin and eosin, x200).
