Martorell hypertensive leg ulcer
Martorell ulcer is thought to be due to subcutaneous arteriosclerosis that develops as a result of increased peripheral vascular resistance occurring in the setting of chronic hypertension. This leads to diminished arteriolar blood flow to the skin, followed by ischemia and ulceration.
Martorell ulcers are often underdiagnosed: a prospective cohort of 59 patients demonstrated a mean duration before diagnosis of 11 weeks and the wound extending to a mean surface area of 19 cm.
