[Multilocular extramammary Paget's disease].

Paget cells were found histologically in a patient with erythemato-erosive lesions on the genitoperineale areas. These cells were also observed in the right axillary skin within a tiny depigmented spot and even in the left axillary skin which was macroscopically almost intact. There were no signs of metastatic or deep-seated adnexal adenocarcinoma. Treatment consisted of radical operation of the pathological lesions with skin grafting and removal of one testicle. After the operation the x-ray irradiation was performed.

Angiolipoma in brothers.

Two brothers with angiolipoma are presented. The patients, 33- and 37-year-old men, have multiple subcutaneous nodules on the trunk and extremities. Skin biopsies have confirmed the diagnosis of angiolipoma.

A case of Schönlein-Henoch-purpura: an immunopathological study.

A case of Schonlein-Henoch-purpura is presented. The immunofluorescent study of skin lesions of the patient showed granular deposits of IgA and C3 in the blood vessel walls perivascular deposits of plasminogen and diffuse localization of fibrin and fibrinogen in the upper dermis. Complement activation via the alternative pathway through IgA, C3 and plasminogen deposits was suggested.

Ultrastructural evidence for lack of tissue damage in a local immune complex reaction: a study of a mild passive Arthus reaction.

An electron microscopic study of a mild reversed passive Arthus reaction (RPAR) was performed using a horeradish peroxidase (HRP)-anti-HRP system to demonstrate the biological usefulness of the process which exists to clear tissue of immune complexes. To disclose the antigen, HRP, the biopsy material was subjected to a peroxidase reaction. HRP was mainly detected within irregular electron-dense precipitates which were considered insoluable HRP-anti-HRP immune complexes. Neutrophils were found to phagocytose and digest the deposited immune complexes in a similar way as described previously. But there was no vascular and other tissue damage. This study provides morphological evidence that the process of clearing tissues of immune complexes need not be harmful to the host.

Vascular permeability-increasing action of hypoalbuminemic substance from Ehrlich ascites carcinoma cells.

A hypoalbuminemic substance (F-3), which was obtained from Ehrlich ascites carcinoma cells, showed a marked vascular permeability-increasing action in mice. The highest increasing effect was produced 20 min after an intradermal injection of F-3. This action was inhibited by diisopropyl fluorophosphate, soybean trypsin inhibitor, and indomethacin but not by hydrocortisone or D-2-bromolysergic acid diethylamide. The inhibition of F-3 by diisopropyl fluorophosphate was observed in partial even after the excess diisopropyl fluorophosphate was removed from the diisopropyl fluorophosphate-treated F-3. The hypoalbuminemic and hypoproteinemic actions were not subjected to any inhibition by the diisopropyl fluorophosphate treatment. The decrease in albumin produced 3 hr after the injection of F-3 would be due to the leakage of albumin from blood vessels. F-3 might contain at least two components, one being a vascular permeability-increasing substance and the other a hypoalbuminemic one.
