To the Editor: Treatment of histiocytosis X is palliative atbest. It includes corticosteroids, alkylating agents, antimetabolites,vinca alkaloids, and irradiation1. Since 2-chlorodeoxyadenosine,a purine substrate analogue active against lymphoid cancers,2is toxic to monocytes in vitro,3 and since tissue histiocytesare derived from circulating monocytes as they move from theintravascular space to soft tissues, we administered 2-chlorodeoxyadenosineto a patient with histiocytosis X.
A 33-year-old woman had presented at the age of 15 years withpolyuria and polydipsia due to diabetes insipidus. Two yearslater vesiculopustular lesions developed on her gingiva, scalp,and vagina that were histologically . . . [Full Text of this Article]
