Livedo racemosa is a cutaneous finding characterized by a persistent, erythematous, or violaceous discoloration of the skin, in a broken, branched, discontinuous, and irregular pattern. A retrospective review of 33 cases with clinical diagnosis of livedo racemosa over the past 6 years was evaluated in the dermatology department of a tertiary care hospital. We found predominance in Caucasian women (78.8%); age ranged from 8 to 81 years, with a mean age of 36 years. Livedo racemosa was described as generalized in 12 patients (36.4%), although the main localization was on lower limbs (42%). After laboratory testing and histopathological examinations, 12 patients (36.4%) were classified with idiopathic livedo racemosa; secondary diseases were diagnosis in 21 patients (63.6%), including Sneddon’s syndrome, cutaneous polyarteritis nodosa, systemic lupus erythematosus, and others. Medical history of thrombotic events was described in 8 (24.2%) patients, and also 8 (24.2%) patients had abnormal results for 2 or more thrombophilia laboratory tests. Skin biopsy showed no histological abnormalities in 11 cases (33.3%), thrombosis of dermal blood vessels in 10 (30.3%), intimal/subintimal thickening in 7 (21.2%), and vasculitis in 5 (15.2%). In conclusion, livedo racemosa is a clinical feature that might be correlated to vascular disorders, such as thrombotic and/or hypercoagulable states, autoimmune diseases, and neoplastic diseases, or it can be secondary to specific medications. It is essential to establish a correct approach in cases of livedo racemosa, which includes anamnesis, physical examination, laboratory test, histological examination, and complementary examination according to clinical findings, in order to diagnosis underlying causes.
