title: Fibroblastic tumor of the urinary bladder after cyclophosphamide therapy.
abstract: An unusual fibroblastic tumor occurred in a teenage boy following treatment with cyclophosphamide for Hodgkin's disease. To our knowledge, only one other similar case has been reported. The cellular and structural composition of the tumor resembles that of cyclophosphamide-induced cystitis and therefore suggests a relationship between the two lesions.
