When a 67-year-old man was admitted to hospital with fluid overload, his doctors were not expecting to find cheetah-like spots covering his upper gastrointestinal tract.

The patient had a history of diabetes, hypertension, ischaemic heart disease and chronic kidney disease.

He was on a dozen medications, including amlodipine, hydralazine, furosemide, glipizide, atorvastatin, omeprazole and iron polymaltose.

During admission for IV diuretics, the doctors noted normochromic normocytic anaemia with a haemoglobin of 85g/L.
