title: Eleven cases of neoplastic microangiopathy.
abstract: Between 1981 and 1988, we recorded 11 patients presenting a neoplastic microangiopathy. All patients suffered from adenocarcinoma, except one with an undifferentiated lung carcinoma; the origin of the tumor was mammary in 5 cases and gastric in 3. In our study, microangiopathy was the first manifestation of the neoplastic disease on 3 occasions; on 7 occasions it was a complication of an advanced stage of a known oncological disease; and on 1 occasion it occurred during a course of intra-arterial chemotherapy. Regenerative anemia (mean 9.5 g/dl hemoglobin), thrombocytopenia (mean 42,000 platelets/mm3), and an elevated LDH value (mean 1,268 U/l) characterized these patients. Disseminated intravascular coagulopathy (DIC) was found in half the cases in which it was sought. In spite of aggressive antitumoral treatment, the course was disastrous with an average survival of 13.6 days. The most frequent causes of death were renal insufficiency or hemorrhagic diathesis. These data corroborate those cited in the literature since 1979, and are consistent with those reported by Antman during the period 1962-1979.
