[Clinical picture of Lyme boreliosis].

Prevalence of Lyme borreliosis in Europe has been well esablished during the last decade. The highest morbidity in Poland, exceeding 100 cases (100.000) year, was demonstrated in north-estern part of the country. Additional small endemic areas were also described in south-western and central part of the country. Clinical picture of the disease do not differ significantly from observed in other parts of Europe. Lyme borreliosis is characterized with a wide variety of manifestations recognized as typical: erythema migrans, borrelial lymphocytoma, acrodermatitis chronica atrophicans, arthritis, facial palsy, lymphocytic meningitis and cardiac transduction disturbances. However there are also controversial syndroms, that have confirmed etiology of Borrelia burgdorferi but only in some cases, such as: morphea sclerodermatous lesions, cardiomyopathy and some neurologic disorders. Diagnosis of Lyme borreliosis is still based on typical signs of the disease and laboratory techniques can not solve clinical doubts.
