The dripping candle wax sign is a radiologic sign seen on X-rays of bone that indicates melorheostosis (or Leri disease), a rare benign bone disease characterized by bone hypertrophy, dysplasia, and sclerosis. [1] Sclerosis typically affects one side of the cortex of the involved bone, appearing similar to wax melting down one side of a candle. [1] Melorheostosis most commonly affects the long bones of the upper and lower extremities, but can also be seen in the hands and feet. [2] It is usually an incidental finding and most patients are asymptomatic. [2]
