The case of a 60-year-old female with severe and rapidly progressing G
ushing's syndrome with fatal consequences is described. Both the clini
cal and the biochemical findings were consistent with ectopic ACTH pro
duction. A computed tomographic (CT) scan revealed intact pituitary an
d enlarged adrenal glands. Liver metastases were seen but the primary
neoplasm was not found. Treatment with aminoglutethimide and other the
rapeutic measures were unsuccessful. A carcinoma of the right ovary wa
s discovered on autopsy. The tumour cells showed immunoreactivity for
neuron-specific enolase (NSE), ACTH and beta-endorphin with differing
degree of intensity.
