[Allergic reactions to teniposide (VM-26) in children with neoplasms].

Allergic reactions of dramatic intensity were observed in 5 children treated with Teniposide (VM-26) for acute lymphoblastic leukaemia and histiocytosis X. In the further treatment this drug was replaced with epoxide, a cytostatic agent which is also a podophyllin derivative but in other chemical formulation. In none of these patients the allergic reaction returned.
