A patient referred to us for recurrent chest wall gouty tophus, but who was determined to actually have a chylous cyst, is described herein. Chylous cysts of the neck or chest wall can be caused by thoracic duct injury. Chyle contains 4–40 gm/liter of lipids, mostly triglycerides, and these can form birefringent crystals upon drying, leading to a false diagnosis of gout.
