Answer

Patient history may reveal the following:

  • Pruritus - Patients with stasis dermatitis typically present with an insidious onset of pruritus affecting 1 or both lower extremities

  • Discoloration - Reddish-brown skin discoloration is an early sign of stasis dermatitis and may precede the onset of symptoms

  • Ankle involvement - The medial ankle is most frequently involved, with symptoms progressing to involve the foot and/or calf

  • Edema - Stasis dermatitis patients may offer a prior history of dependent leg edema

Isoda et al reported a case of stasis dermatitis resulting from an artificial arteriovenous fistula that was created in the patient 33 years previously, during treatment for poliomyelitis. [22]

Factors that worsen peripheral edema (eg, congestive heart failure, long-standing hypertension with diastolic dysfunction) are often found in patients with stasis dermatitis. Some antihypertensive medications (such as amlodipine) may increase leg edema and trigger the onset of stasis dermatitis. [23]
