Cell-free extracts of the human rhabdomyosarcoma cell line HUS-2 caused the transformation of human embryo fibroblasts. This transformation included morphologic alteration, karyotypic change, and an increase in culture longevity. With the use of sex markers, multiple karyotypes confirmed that the human embryo fibroblasts were transformed, and the use of cell-free material further suggested the presence of a transforming virus. RNA-dependent DNA polymerase activity in a particle with a specific gravity of 1.16 g/cm3 indicated the presence of an RNA type C virus. Evidence also suggested that the known mammalian type C viruses, routine cytopathic effect-inducing viruses, or mycoplasma were not the agents responsible for the transformation. That both the donor (HUS-2) and converted (HUE-T) cell lines cross-reacted with antisera prepared against HUE-T indicated a common antigen arising in the process of conversion of HUS-2 cells to HUE-T cells.

Acute cold haemagglutinin disease, most commonly associated with underlying mycoplasma infection, is rare in children. A 3-year-old girl who developed this auto-immune disease under intensive cytotoxic treatment for rhabdomyosarcoma is presented. Clinically, a livedo reticularis skin pattern upon exposure to cold which was reversible at room temperature and a spontaneous red cell agglutination of blood samples in vitro led to the diagnosis. Together with bronchopneumonia the girl developed hyper-IgM, high antibody titres against Mycoplasma pneumoniae, as well as high titres of cold agglutinins. Laboratory signs of mild intravascular haemolysis were found. Positive direct antiglobulin test resulted from coating of red cells with C3d and C4. Three different antibodies were identified in serum: nonspecific cold agglutinins without complement activation, anti-I specific cold agglutinins with complement activation, as well as a weak biphasic Donath-Landsteiner haemolysin. Under antibiotic treatment and a short course of predisolone the clinical course was mild.
