Introduction: Leg ulcers are a health issue due to the number of people affected by it and its chronicity, with heavy impact in life quality. Goals: To determine the leg ulcer’s prevalence rate. To characterize and analyse the connection between the socio-demographic aspects, the risk factors, the ulcer’s and its’ treatment’s characteristics by classifying the leg ulcer. Methodology: Epidemiological, analytical and transversal study. The sample comprehends 63 outpatients with leg ulcers from the following health centres: Bom Jesus, Ponta de Sol, São Vicente, Santa e Arco da Calheta. Results: The prevalence rate was 1,57/thousand inhabitants with an incidence rate of 14,58/100 thousand inhabitants in 3 months. Outpatients were mainly elderly females, with low education levels, retired and obese. The most validated risk factors included peripheral venous insufficiency, obesity, hypertension and mellitus diabetes type 2. The most frequently used diagnostic method was clinical evaluation (100%), in which 14,3% tested for ABPI. The etiology was predominantly venous (90,5%), mixed (7,9%) and arterial (1,6%). The ulceration’s chronicity had an average of 1097,3 days. Concerning the ulcer’s characteristics it was possible to observe a predominance of fibrous tissue, with a moderate exudate and surrounding dry skin. The most frequent debridement type used was the enzymatic one, applying collagenase. Signs of infection were evidenced in 42,9% of the sample, generally with an increase of exudate and its viscosity; increase in pain and odour. Less than half, 48,1%, were submitted to systematic antibiotherapy. The majority manifested pain (65,1%), which increased after the treatment, and 63,4% of these had analgesia. Compressive therapy was performed in 11,1% of outpatients and 69,8% were submit to pharmacological agents. It has been validated a significant relation between: neoplasia and the ulcer’s classification (p=0,024); former bone fractures and the leg ulcer’s classification (p=0,016); and a relation between the presence of a signs of infection with its area (p=0,005). Conclusion: The prevalence of the leg ulcer is similar to the ones publicised in other European research studies, requiring high demand of resources and bearing repercussions to both the outpatient and those around
