  • Title: Atypical ischemic lower extremity ulcerations: a differential diagnosis.
    Author: Dean SM.
    Journal: Vasc Med; 2008 Feb; 13(1):47-54. PubMed ID: 18372440.
    Abstract:
    Severe peripheral artery disease (PAD) is the predominant cause of ischemic ulcerations involving the lower extremities. PAD-associated ulcerations are typically distally located involving the feet, toes, and sometimes the calves. In contradistinction, atypical ischemic ulcerations of the lower extremity are often non-atherosclerotic in etiology, involve the proximal leg (thigh/buttocks), can evolve despite palpable distal pulses, and may coexist with other cutaneous aberrations (e.g. macules, purpura, nodules, and livedo reticularis). A differential diagnosis of atypical ischemic ulcerations involving the legs is presented.
