Fluorescence-guided resection with 5-ALA may be useful for resection of subependymomas of the fourth ventricle. However, further studies are needed.

To our knowledge, this is the first case published in the literature of meningeal sarcoma in a child in which intraoperative fluorescence with 5-ALA was used to achieve a complete resection.

2 patients with acute allergic contact dermatitis from 3-(aminomethyl)-pyridyl salicylate are described. Both patients were females with histories of urticaria and showed cross-sensitization to substances of the para group. Clinical manifestations included eczema, angioedema and respiratory effects. In 1 patient, airborne elicitation was suspected. A lymphocyte transformation test confirmed the allergy, with an extremely high response index. 35 normal controls were negative.
