In order to attain a better understanding of the varied morphology of neoplasms of the adrenal cortex, medulla and extraadrenal paraganglia, structural aspects of normal anatomy, including hyperplasia, are illustrated here. Numerous new colour illustrations appear in this edition, and a large number have been replaced or upgraded using high quality transparencies for digital imaging. The contributions of cytology and fine needle aspiration biopsy in diagnosis are emphasised, particularly with respect to adrenal tumors. Emphasis is also placed on the important role of molecular pathology and immunohistochemistry in tumour diagnosis, and in some cases may provide valuable information regarding prognosis.
