RESUMO
INTRODUCTION: Livedoid vasculopathy is a rare dermatological condition characterized by painful ulceration, atrophic scarring, and persistent livedo reticularis. The pathogenesis is unclear. METHODS: We report a patient with biopsy-proven livedoid vasculopathy who developed a progressive sensory ganglionopathy with profound sensory ataxia. Serial nerve conduction assessments were undertaken. RESULTS: Combined treatment with prednisolone and mycophenolate mofetil failed to control the ganglionopathy. After addition of rituximab, both symptoms and nerve conduction studies showed stabilization. CONCLUSIONS: Sensory ganglionopathies associated with autoimmune and inflammatory conditions may be characterized by a sub-population of "sick" dorsal root ganglia that can be rescued with aggressive immunotherapy.
