[A patient with an immunodeficiency and consecutively 3 primary malignancies].

Patients with a primary immunodeficiency syndrome have an increased risk of the development of a malignancy. Lymphoreticular malignancies are the most common malignancies in these patients. Patients with ataxia telangiectasia (AT) also appear to be at a high risk for the development of non-lymphoid tumors, in particular carcinomas of the gastrointestinal tract and central nervous system tumors. We describe a child with an immunodeficiency and slight neurologic manifestations. During childhood she developed consecutive three primary malignancies.
