title: Calcification in undifferentiated abdominal malignancies.
abstract: Four cases of undifferentiated abdominal malignancy are reported with a pattern of bizarre dystrophic calcifications. All of the cases had confusing histology and were long-term survivors; two being still alive. We feel that the radial, conglomerate masses of calcification, which do not conform to any organ, should suggest the diagnosis of an undifferentiated malignancy. The differential diagnosis and distinction from other causes of abdominal calcification is discussed.
