Dark after cholecystectomy.

ABSTRACT

We report a patient who complained of becoming darker after an abdominal surgery. The index patient not only had a darker complexion after cholecystectomy, but his glycaemic control was also getting better after operation to the extent that he could stop insulin, which he had been taking for five years. Also, he had lost significant weight after operation. Later, we found that he had developed primary hypocortisolism due to unrecognized bilateral adrenal haemorrhage in the immediate postoperative period.
