[A case of severe combined immunodeficiency]. / Su un caso di immunodeficienza combinata grave.

The case described presented notable problems of diagnosis and treatment. The rapid onset of a massive tumoral syndrome in an infant with bronchiolitis dramatically worsened the clinical picture and led to the infant's death, posing the problem of the forms of congenital immune deficiency that may be associated with various aplastic and dysplastic haemopoietic alterations. The possibilities of treating such early hyperacute cases are limited given the lack of knowledge about the effects of drugs in such young children and the rapid deterioration of the patient's condition.
