The sections show a lesion in the medulla of the adrenal gland that is arranged in nests (Zellballen). The tumour cells have abundant grey/blue granular cytoplasm, and nuclei with granular chromatin (salt and pepper chromatin). The lesion is surrounded by a compressed rim of adrenal cortex and fibrosis tissue. The core of the lesion is fibrotic and has clusters of hemosiderin-laden macrophages. | |||
There is no capsular invasion. Vascular invasion is not identified. There is no necrosis. Mitotic activity is not appreciated. | |||
The adrenal cortex is unremarkable. | |||
