RESUMEN
Familial hemophagocytic lymphohistiocytosis (FHL) is a rare disease characterized by fever, hepatosplenomegaly, cytopenia and non-malignant lymphohistiocytic infiltration with hemophagocytosis in reticulendothelial organs. We experienced three cases of FHL in identical male twins and their younger brother who presented with fever and severe hepatosplenomegaly. Cytopenia, elevated serum transaminase and low serum albumin levels, hypertriglyceridemia were common laboratory findings of them. One of them showed markedly decreased phytohemagglutinin induced lymphocyte proliferation and reversed CD4/CD8 ratio (0.52) in flowcytometric lymphocyte subset analysis. Aspirate of bone marrow revealed typical features consistent with FHL in two of them. In spite of recent therapeutic approaches, none of them survived.

Chondrodysplasia punctata is a rare congenital disorder of bone, occuring in infants, which is characterized by radiographic manifestation of premature deposition of punctate calcific densitiy in epiphyseal areas, preformed in cartilage. We experienced a case of rhizomelic type-chondrodysplsia punctata in a two day old female who showed short stature, symmetric shortening of proximal limbs, cataract, icthyositic skin lesion and characteristic coronal clefts in lumbar vertebral bodies on X-ray.
