[Auto-immune haemolytic anaemia and mediastinal dysembryoma in a 6-year-old child (author's transl)].
In a six-year-old girl, suffering from an auto-immune haemolytic anaemia, routine radiological examination revealed the presence of a mediastinal tumour which was removed surgically and proved to be a multiple tissue polycystic dysembryoma. Haemolysis and signs of anti-erythrocyte auto-immunisation disappeared after the operation and total and stable cure obtained with a follow-up of 15 months. The target antigen of the anti-erythrocyte autoantibody could not be found within the tumour. However, the latter contained lymphoid tissue and a considerable quantity of antibody. Although indirect, these findings offer arguments in favour of the secretion of autoantibodies by the dysembryoma.
