Differential Diagnosis

• EIV is commonly associated with golfers, hikers, and long-distance walkers over the age of 50, especially in hot climates. 1-4 This case may support that there is a broader range of underreported cases of EIV that do not fit this demographic. • Most cases resolve spontaneously within 10 days with supportive treatment, 1 but other treatments should be considered if the lesions are not improving with symptomatic treatment or there is necrosis or ulceration. 5 • Most literature does support that exercise-induced vasculitis is a diagnosis of exclusion and that other causes of systemic small-vessel vasculitis such as ANCA vasculitis, Henoch-Schölein purpura, and hepatitis should be considered. 5 • Hypotheses for the pathophysiology include: exercise-induced immune complexes cause complement activation and inflammation of vessels or disruption of the body’s vasculature response to exercise. • Increased body temperature causes vasodilation, while the SNS causes vasoconstriction in response to exercise. • Lipedema or venous insufficiency can disrupt these two systems, causing venous overfilling and extravasation of blood into the skin. 1,3-4,6 • Cases of EIV should continue to be reported, as many people are misdiagnosed and mistreated initially for a benign condition.

• Subjective • A 34-year-old male presented to the emergency department for bilateral lower leg rashes that began 3 days prior. The rash had gotten progressively larger and darker. • He denied any significant past medical history or trauma. • He worked at a large store stocking, which required prolonged standing and walking throughout his workday. • Objective • Vitals: Temp. 98.2 ° F, HR 92 BPM, RR 18, SpO2 96%, BP 172/98 • Weight: 154 kg • Constitutional: Obese male • Skin: Warm and dry, capillary refill <2 seconds, bilateral lower extremities with nonpalpable, non-blanching, non-tender rash that cuts off at sock line without involvement of the feet • Assessment • Exercise-Induced Vasculitis • Plan • Supportive care: elevate the legs, compression stockings, NSAIDs and antihistamines as needed • Follow-up with PCP if symptoms have not resolved in 4 weeks for further workup and treatment. • Exercise-induced vasculitis (EIV) is a benign cutaneous small-vessel vasculitis that is underreported, often leading to an extensive workup at presentation. 1,2 • The skin lesions, also known as “golfer’s vasculitis” and “hiker’s rash”, often present in people who participate in activities that require prolonged walking and standing . 3,4 • Hot climates are a known trigger for EIV, and women are more commonly affected than men. 1,3 • EIV usually presents initially in people over the age of 50, and relapses commonly occur. 1-4 • The rash brought on by EIV is often pruritic or is accompanied by a burning sensation, although it can be asymptomatic. The sock area is often spared. It also usually resolves spontaneously within 10 days. 1-4 • Current literature supports performing extensive workup to rule out systemic causes of vasculitis at presentation. 5 Case
