Histopathological classification of adrenal tumours.
Tumours in the adrenals originate from the adrenal cortex, the adrenal medulla or as metastases from extra-adrenal primaries. Differentiating between these three groups is the first task a pathologist has to tackle when dealing with specimens from the adrenal region. Whereas this is possible in every case with total removal of the adrenal tumour it may be impossible in fine needle biopsies of such tumours. The second great problem is the dignity of adrenal tumours, which cannot be determined in many adrenomedullary and some adrenocortical tumours. Immunostainings are helpful but the basic method remains the histopathological examination of paraffin sections. This review gives an update of pathological findings in several adrenal tumour entities, and provides guidelines for the diagnosis of these tumours in the light of recently published data.
