From a histopathological viewpoint, it is characterised by thrombosis of the dermal arteries, with no leukocytoclastic vasculitis. Patients typically present purple-coloured macules, which may progress to ulcers and leave white scars after healing (atrophie blanche).<a class="elsevierStyleCrossRefs" href="#bib0005"><span class="elsevierStyleSup">1,2</span></a> In some cases, LV has been associated with mononeuritis multiplex (MM) secondary to thrombosis of the vasa nervorum. We present the first reported case of vasculitic MM associated with LV.</p><p id="par0010" class="elsevierStylePara elsevierViewall">Our patient was a 58-year-old man with no relevant medical history, who presented 2 months’ progression of pain and progressive loss of strength and sensitivity in both feet, associated with erythematous lesions on the tops of the feet. He also reported loss of sensitivity in the fourth and fifth fingers of the right hand. He presented no constitutional symptoms and had no history of systemic disease.</p><p id="par0015" class="elsevierStylePara elsevierViewall">The examination detected confluent erythematous macules in both feet, compatible with livedo racemosa, and no ulcers or atrophie blanche. Muscle strength was 3/5 in plantar flexion and 2/5 in dorsiflexion. Patellar and Achilles reflexes were absent in the left limb and hypoactive in the right. The patient also displayed reduced tactile and pain sensitivity below the knees and in the fourth and fifth fingers of the right hand. The remaining results of the neurological examination were normal.</p><p id="par0020" class="elsevierStylePara elsevierViewall">Laboratory analyses yielded normal results, including normal levels of homocysteine, cryoglobulins, lupus anticoagulant, and rheumatoid factor. Tests for antinuclear, antineutrophil cytoplasmic, anti-®2 microglobulin, anticardiolipin, antiganglioside, and antineuronal antibodies returned negative results; results from serology tests for syphilis, hepatitis B and C viruses, and HIV were also negative. CSF analysis yielded normal results, with no oligoclonal bands. Screening tests for hereditary thrombophilia and occult cancer yielded negative results.</p><p id="par0025" class="elsevierStylePara elsevierViewall">A neurophysiological study detected increased distal latencies and low-amplitude motor evoked potentials in the peroneal and tibial nerves. Somatosensory evoked potentials were not detected in the sural nerves. Low-amplitude motor evoked potentials were detected in the right ulnar nerve. Electrical activity was normal in both median nerves and the left ulnar nerve.</p><p id="par0030" class="elsevierStylePara elsevierViewall">A skin biopsy revealed occlusive vasculopathy in the superficial and deep dermal arteries, with areas of mural hyalinisation, no inflammatory infiltrate, and preserved epidermis; these findings are consistent with LV (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). A sural nerve biopsy revealed intense loss of myelinated fibres. An epineurial artery showed CD45+ inflammatory infiltrate, with arterial wall infiltration and destruction (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>). No thrombosis was observed in other arteries.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><elsevierMultimedia ident="fig0010"></elsevierMultimedia><p id="par0035" class="elsevierStylePara elsevierViewall">The patient was treated with acetylsalicylic acid at 100 mg/day, prednisone at 1 mg/kg/day, and amitriptyline and tramadol as rescue medications; treatment relieved pain and strength and sensitivity progressively improved. Skin lesions improved progressively, leaving no atrophie blanche. A year after the first consultation, the patient presented deep vein thrombosis in the right leg, which was attributed to immobilisation and treated with acenocoumarol for 6 months. Again, tests for thrombophilia and occult cancer yielded negative results. The dose of prednisone was gradually reduced, and the drug was suspended at 19 months. The patient remains asymptomatic after 6 years of follow-up.</p><p id="par0040" class="elsevierStylePara elsevierViewall">LV was diagnosed based on the characteristic skin biopsy findings.<a class="elsevierStyleCrossRef" href="#bib0005"><span class="elsevierStyleSup">1</span></a> The condition is not always associated with atrophie blanche.<a class="elsevierStyleCrossRefs" href="#bib0005"><span class="elsevierStyleSup">1,2</span></a> The pathogenesis of LV is unclear.
