[A paraneoplastic acrosyndrome].

BACKGROUND: Paraneoplastic digital ischemia is an uncommon complication of metastatic adenocarcinomas. CASE REPORT: Two years after remission of an uterine adenocarcinoma, the patient developed an acrosyndrome involving all four limbs with digital ischemia. Recurrent carcinoma was evidenced by a very high antinuclear antibody titer. Chemotherapy improved the acrosyndrome. DISCUSSION: Vasomotor disorders which developed in older subjects with no other signs of autoimmune disorders should suggest a neoplastic origin. Icshemia of the fingers would be caused by vasculitis. An elevated antinuclear antibody titer may be a supplementary argument suggesting a neoplastic etiology.

[Mixed corticomedullary tumor].

BACKGROUND: Pheochromocytoma and primary hyperaldosteronism rarely occur simultaneously. Few cases have been reported in the literature. CASE REPORT: A patient explored for hypertension was found to have hypokalemia related to primary hyperaldosteronism. Pathology examination of the ablated adrenal showed a co-existing pheochromocytoma suspected at history taking although urine catecholamines were normal. DISCUSSION: Different pathogenic hypothesis have been proposed. Such dual tumors could be a simple coincidence, occur in a particular genetic setting, be related to direct contact between cortical and medullary tissue leading to reactional cortical hyperplasia, pheochromocytoma produced factors stimulating aldosterone synthesis, or factor X, a substance produced by cortical adenomas and favoring growth of the pheochromocytoma.
