Histopathology findings of the ectopic adrenocortical oncocytic adenoma. a The neoplasm was partially encapsulated with a thin capsule (HE x 100). b The tumor cells contact directly with hepatocytes with no capsule (HE x 100). c Large, eosinophilic polyclonal cells were intermixed with smaller, clear cells mimicking the zona fasciculata of the adrenal gland (HE x 100). d Nuclear polymorphism and nucleoli were obvious in eosinophilic cells (HE x 200)
