title: [Demonstration of plasmacytes in gingival immune defense units in dermoid cysts of the ovary].
abstract: Gingival units of immunological defense have been observed surrounding erupted teeth in the connective tissue of the wall of ovarian dermoid cysts. Using a modified immunoperoxidase technique, the production of IgA, IgG and J chains has been clearly detected. This technique works perfectly on decalcified specimens. Since dermoid cysts are not contaminated, the origin of the plasma-cells in these units is presumed to be triggered by other antigenic factors. These are present in epithelium and provided a possible explanation for the "homing" of lymph-cells migrating from the immune system.
