Lyme Borreliosis as a Trigger of Dermatomyositis and Cerebral Thrombosis. Clinical Presentations of This Unusual Manifestation of Lyme Disease

Lyme disease represents a multisystemic tick-borne disease transmitted by ticks from the Ixodes genus. It is estimated a number of 20-100 cases per 100000 inhabitants in North America and around 100-130 cases per 100000 inhabitants in Europe. The disease evolution in stages is easily to be recognized when knowing the moment of the tick bite and it gets difficult in cases where this moment cannot be determined. Diagnostic difficulties are justified by the lack of recognition of the time of the bite in about 64% of cases of Lyme disease in Europe, and in 2530% of cases in the United States. The association of Lyme disease with dermatomyositis and the occurrence of cerebral thrombosis secondary to neurbororreliosis are rarely found in the literature. We intend to present two clinical cases with these particular aspects.
