Pathological findings of the resected tumor. (a) Pathological examination revealed the tumor was surrounded by a thin fibrous capsule on macroscopic findings. (b) Hematoxylin–eosin (HE) staining showed that the lesion was composed of cells with a micro-vesicular cytoplasm, and these were aligned in alveolar or trabecular arrangements. (c) Foci formation was similar to that of adrenocortical tissue on silver plating.
