[Abscessing lymphadenitis in a 1.5-year-old boy].

At present, Bartonella species are increasingly important as infectious agents in both animals and humans. Bartonella henselae, the most frequently diagnosed species, is known to cause numerous clinical syndromes in both immunocompetent and immunocompromised patients. In healthy individuals, the infection is most commonly manifested as the so-called cat scratch disease. The manifestations include erythema or papule at the point of entry of infection (site of injury) and regional lymphadenitis. The aim of the case report is to present the disease as one of possible causes of colliquative cervical lymphadenitis.
