Summary

Rumpel-Leede phenomenon (RLP), also known as acute capillary rupture syndrome (ACRS), is a rare occurrence where distal dermal capillaries rupture in response to a proximal compressive force, such as a blood pressure cuff or tourniquet. This phenomenon has been reported to occur in states of vascular fragility such as long-term steroid use, hypertension or diabetes mellitus. Here, we provide a report of RLP occurring secondary to tourniquet application in a 26-year-old woman with adult-onset Still's disease (AOSD) and a recent drug rash. In this case, the cause of the phenomenon is most likely multifactorial. Likely contributing factors include long-term steroid use for the treatment of AOSD, and increased vascular permeability secondary to the drug rash. Patients and clinicians should be aware that the treatment of AOSD may induce a state of capillary fragility and they should work together to minimise the risk of complications.
