A case of Kimura's disease of the hard palate.

A 33-year-old man presented with Kimura's disease of the hard palate. Serological examination showed no elevation in the number of eosinophils or in IgE level, but histological examination revealed well-developed lymph follicles with increased numbers of eosinophils. In addition, immunohistochemical examination revealed that the IgE concentrations were shown in the lymphoid follicles with germinal centers, a finding typical of Kimura's disease. The patient underwent surgical resection followed by treatment with non-steroidal anti-inflammatory drugs (NSAIDs). Throughout the 2-year follow-up period, the patient's condition has remained satisfactory.

[Evaluation of new drug delivery system for primary lung cancer: intermittent intra-arterial injection therapy with implantable port system (reservoir)--II. Evaluation of technical methods for cannulation of feeding arteries of lung cancer with implantation of implantable port system].

As mentioned in the first of the present series of reports, lung cancers were fed by various arteries such as bronchial arteries, internal mammary arteries, inter-costal arteries and branches of subclavian arteries such as thyro-cervical truncus or thoraco-dorsal arteries, according to the size and stages of tumors and the processes of therapy. On the basis of these anatomical findings of the feeders of lung cancers, we tried several effective and reasonable ways of cannulation of catheters, which were connected with an implantable port system.

[Evaluation of new style of drug delivery system for primary lung cancer: intermittent intra-arterial injection therapy with subcutaneous infusible port I.--Temporary changes in feeding arteries of lung cancer in processes of intra-arterial injection therapy].

Arterial injection therapy for lung cancers is concentrated on the bronchial arteries, because they are reported by the main feeders of lung cancers. In the present study, we attempted intermittent arterial injection therapy with implantable port system. In the cases of lung cancers, in the present study, tumors were mainly fed by bronchial arteries originating from intercostal-bronchial arteries in right lungs, and those directly originating from aorta in the left lungs. However, in the processes of BAI (Bronchial Arterial Injection Therapy), main feeders often were obstructed and the new feeders originated from branches of subclavian arteries, such as thyro-cervical truncks, internal mammary arteries, thoraco-acromial arteries and intercostal arteries. They formed networks surrounding the lungs. Adequate study of the feeding arteries should be performed in the course of arterial injection therapy of lung cancers.
