Histologic aspects of patch test reactions in allergic contact dermatitis. | Twenty subjects with allergic contact dermatitis were patch tested with the responsible allergen applied to four fixed points on the back. Skin biopsies of the four sites were obtained after 6, 12, 24 and 48 hours, fixed in neutral formalin and stained with hematoxylin-eosin, Giemsa and toluidine blue. Sections were ex... | 738,038 | [
