In children, as in adults, bilateral adrenocortical hyperplasia occurs in one of three forms (Neville and Symington, 1967): simple hyperplasia, nodular hyperplasia or hyperplasia associated with " non-endocrine " tumours that secrete ACTH or an " ACTH-like " peptide (table 111) previously considered to be bilateral adrenocortical adenomas or adenomas with attached hyperplastic glands (Lightwood, 1932;Marks, Thomas and Warkany, 1940;Powell, Newman and Hooker, 1955).
