Background Martorell hypertensive ischemic leg ulcers are commonly misdiagnosed, and their prevalence may be underestimated. There are still some aspects to be defined about the aetiopathogenesis of Martorell ulcers and the risk factors that may be involved with them. Methods This is a single-centre retrospective case series study on the demographic characteristics and comorbidities in a series of patients with Martorell ulcer treated at a public university hospital in Madrid. Results Comparing our results to previous studies, which are few and include small samples, the risk factors that we outline are an average age over 70 years and high blood pressure. Only two (5%) participants had poor control of their high blood pressure. Conclusions and Implications for Clinical Practice Defining the epidemiological features of this type of leg ulcer may be very useful in differential diagnosis with other disorders, such as pyoderma gangrenosum.
