We describe an infant with juvenile chronic myelogenous leukemia (JCML), the diagnosis of which was made by the characteristic clinical and hematologic findings. The absence of a related HLA-compatible donor for bone marrow transplantation coupled with the awareness that chemotherapy is usually ineffective prompted our decision to treat the patient with lymphoblastoid interferon-alpha [alpha(Ly)-IFN]. During the 26-month course of treatment with alpha(Ly)-IFN an incomplete regression of hematologic and clinical findings was achieved. The above results, along with the easy administration and absence of considerable side effects, suggest that alpha(Ly)-IFN may be a useful therapeutic tool in patients affected by JCML awaiting bone marrow transplantation.

The authors report a case of congenital rubella in a 7-month-old female infant presenting a Blueberry Muffin Rash. Blueberry Muffin Syndrome is a cutaneous manifestation characterized by widespread maculo papular lesions of a reddish-blue or magenta colour, due to persistent dermal erythropoiesis in patients with congenital viral infections.

Here we report two children with Aase-Smith syndrome (triphalangeal thumbs and congenital red cell plasia). In vitro growth of erythroid colonies was normal in the first patient and totally absent in the other. In both patients, treatment with glucocorticoids induced remission of anemia. Our results suggest that the different growth patterns of erythroid colonies observed in the two patients could reflect the defect of erythroid differentiation occurring at discrete maturational levels.

The authors report a case of an infant affected by isolated thrombosis of splenic vein. They stress the necessity of a precious diagnosis in order to prevent the haemorragic consequences of distrectual portal hypertension. Splenectomy, the only therapeutic mean considered in these patients, has been followed, in our patient, by reimplantation of splenic tissue, in order to prevent the septic complicances (mainly due to pneumococcus) frequently occurring in splenectomized patients.
