ABSTRACT

Lyme borreliosis is a systemic disease. The etiologic agent is a tick-bite borne spirochete (Borrelia burgdorferi) of which men are casual hosts. Although the illness is reported worldwide, it is more frequent in the northern parts of Countries. Some isolated clinical pictures are reported in the past, but only in 1975 the illness was well described at Old Lyme (Connecticut, Usa) and then well defined in its pathogenesis and clinical course in three stages. Lyme disease, involving skin, heart, nervous system and joints, is frequently protean and misdiagnosed, so that it was called "the new great imitator". In Italy the first case is reported in 1985. The authors report three (3) new cases, mostly with neuro-articular signs and symptoms. Literature is partially reviewed, for a better definition and outline of some epidemiological, etiopathogenetic, historical and clinico-therapeutic aspects of Lyme disease.
