title: [Familial lymphohistiocytosis. Anatomopathological study of 2 cases detected neonatally].
abstract: Two brothers presented with hemophagocytic reticulosis with neonatal onset. Early clinical and biological symptoms included pallor, hepatosplenomegaly and anemia, thrombocytopenia. Evolution was lethal in both cases, at 5 months and 13 days of age, respectively. Diagnosis was confirmed in both by the pathologic findings: diffuse lymphohistiocytic cellular proliferation with hemophagocytosis and atrophy of the lymphoid tissue. The diagnostic difficulties of this disease in the neonatal period are emphasized.
