Specific and nonspecific lymphadenitis in childhood: etiology, diagnosis, and therapy

Over a period of 4 years, 39 children with lymphadenitis were treated surgically; in 31 cases cervical lymph nodes were the main location. In 9 cases the lymphadenitis was caused by mycobacterial infection. Staphylococcus aureus was the most frequent causative organism of unspecific lymphadenitis (11 cases). The therapy of choice appears to be surgical treatment and medical care after operation. Especially in mycobacterial lymphadenitis, complete surgical excision of the lymph node is decisive for definitive healing. There was only 1 case of therapy-resistant, relapsing cervical lymphadenitis that needed a second operation. Causative organisms in this case were Mycobacterium avium and Mycobacterium intracellulare. All other patients showed an uneventful postoperative clinical course. We believe that a consequent diagnostic process and cooperation between the pediatric surgeon and pediatrician are necessary for effective therapy.
