A 15-year-old female patient presented with orthostatic erythema in the limbs for half a year. Skin examination revealed that diffuse reticular erythema appeared in the limbs after standing with her arms hanging down for 30 seconds, while the erythema disappeared and skin color returned to normal after raising her arms or lying flat for 30 seconds. The rash in the limbs was reproduced by inflating a sphygmomanometer cuff to 60 mmHg for 2 minutes with the limbs in the horizontal position. Antinuclear antibodies were positive at a titer of 1 ∶1 000. Histopathological examination showed dilated small vessels in the superficial dermis without obvious inflammatory cell infiltration. The patient was diagnosed with gravitational erythema.
