Abstract
Ataxia telangiectasia (AT) homozygotes have an increased risk for development of Hodgkin's disease (HD). Parenchymal lung involvement is not uncommon in HD; however, cavitary pulmonary lesions are quite unusual. We report on 3 cases of AT with HD who had mediastinal disease and parenchymal pulmonary involvement with cavitation. Of 6 AT patients in our HD series, 3 developed pulmonary cavities. The patients displayed pulmonary infiltration, cavitation in the lung parenchyma, and mediastinal enlarged lymph nodes on both plain chest X‐rays and thoracic computed tomographies. No infectious etiologies were established for the pulmonary findings. Histopathological examination of open lung and mediastinal biopsies revealed HD, and all patients received multiagent chemotherapies. The outcome was fatal in all 3 patients. Respiratory infections are the principle cause for morbidity and mortality in AT patients. Reports on cavitating pulmonary lesions in HD are quite rare. Furthermore, data regarding the patterns of pulmonary involvement in AT patients with or without HD are lacking. The increased incidence of malignancies in AT patients may relate to immunodeficiency and to the chromosomal alterations identified. Pediatr Pulmonol. 2002; 33:399–403.
