[Paraneoplastic symptoms of neuroblastoma (author's transl)].

Frequently the first clinical sign of neuroblastoma is not caused by local or metastatic tumor growth but is a paraneoplastic symptom (PNS). Such PNS are fever, diarrhea, hypertension, weakness of muscles, Horner's syndrome and myoclonic encephalopathy. Certain PNS disappear with tumor removal, other do not. The clinical importance of PNS is the prognostic and especially diagnostic value. The pathogenetic relations between tumor and PNS as discussed in the literature are interesting but mostly speculative. Effects of Catecholamines and/or immunologic reactions are thought to be the most probable cause of PNS.--The article is based on current literature; in addition, two short case histories are presented.

[Immunological cell markers on lymphoblasts of patients with acid phosphatase positive acute leukemia (author's transl)].

Blast cells of 4 patients with acid phosphatase positive acute leukemia were investigated for T and B lymphocyte markers. Nearly all blast cells showed a typical T cell marker, namely spontaneous rosette formation with sheep red blood cells. No surface immunoglobulin was demonstrable on these cells. 3 of these 4 patients showed an enlargement of the upper mediastinum most probably due to the thymus. The conclusion is drawn that the acid phosphatase positive acute leukemia is a T cell leukemia. Some clinical data about these 4 patients are given.

Liver disease with periportal sinusoidal dilatation. A possible complication to contraceptive steroids.

Four women of fertile age on long-term treatment with contraceptive steroids developed moderate liver damage and hepatomegaly. The liver histology showed a conspicuous periportal sinusoidal dilatation as the only abnormality. The clinical course of the liver damage was benign. The aetiology and pathogenic mechanisms of these changes, which were localized predominantly to Rappaport's Zone I, are unknown. Haemodynamic studies revealed no abnormalities. The connection to possible long-term action of oestrogens and gestagens on the liver, and the relation to peliosis and benign hepatic adenomas, are discussed.
