[Features of generalized infections masking basic disease: non-Hodgkin's large cell anaplastic lymphoma and hemophagocytic syndrome shown in two patients].

The authors describe diagnostic problems encountered while treating two children finally diagnosed to have anaplastic lymphoma in the first case and infection-associated haemophagocytic syndrome (IAHS) in the second. Both diseases represented secondary immunodeficiencies masked by local and systemic severe infections.
