Adrenal tumours may occur at any age, but predominate in children, particularly carcinomas. Their underlying aetiology is not known.
Adenomas are slower growing than carcinomas and are usually of moderate size (1.5ΓÇô6cm diameter) at presentation; rarely they are part of the multiple endocrine neoplasia (MEN) syndrome, type 1.
Excess androgen production is common with adrenal tumours, but is usually only severe enough to cause virilisation with carcinomas. Occasionally, functioning or non-functioning adrenoconical adenomas are found unexpectedly during abdominal CT scanning for unconnected reasons (ΓÇÿincidentalomasΓÇÖ).
