The Rumpel–Leede sign is a historical exam for Dengue fever and scurvy.
It presents as a distal shower of petechiae that occurs after the release of pressure from a tourniquet or sphygmomanometer.
[1]: 824 [2] The blood pressure cuff should be inflated to a pressure between the systolic and diastolic pressures and kept inflated for 5 minutes.
A few minutes after releasing the tourniquet if there are more than twenty petechiae per square inch it is a clinical manifestation of scurvy.
