R. Wright-pascoe et E. Williams, The ectopic ACTH syndrome and superior vena cava obstruction due to a malignant carcinoid tumour of the thymus, W I MED J, 48(3), 1999, pp. 155-157
We report the case of a 28-year-old African Caribbean woman with Gushing's
syndrome and superior vena cava obstruction secondary to an ACTH-secreting
carcinoid tumour of the thymus. The case highlights the problems which may
be encountered in performing the 2-day high dose dexamethasone suppression
test but clinicians are reminded that this test or any other dynamic test i
s absolutely essential for elucidating the cause of ACTH-dependent Gushing'
s Syndrome.
