title: Lipoidal bladder concretion: an unusual autopsy finding in acute lymphoblastic leukemia.
abstract: The occurrence of a large (2.3 gm.), wax-like, creamy white concretion in the bladder of a 7-year-old girl who died of acute lymphoblastic leukemia is reported. Lipids constituted 40% of the total weight and triglycerides accounted for 95% of the total lipids. The fatty acid composition of the individual lipid classes showed a predominance of saturated fatty acids (75 to 80%). Factors influencing the pathogenesis of the material are discussed. A review of the literature on childhood leukemia showed no reference to such lipid abnormalities and the occurrence of this type of concretion has not been reported previously.
