    Notes: Summary Ten cases of nodular sclerosing Hodgkin's disease involving lymph nodes were studied by electron microscopy to determine the ultrastructural composition of the nodule-stromal interphase and the collagenized regions. In addition to a few lymphocytes, rare eosinophils and neutrophils, abundant filamentous and granular electron dense material, collagen fibers and myofibroblasts were observed in all instances. Since myofibroblasts possess contractile and synthetic properties, it is likely they contribute to the retraction and sclerosis which together represent one of the morphologic hallmarks of the disease. The dense fibrosis and contractile state of such tissue may constitute a beneficial host response to contain and limit local and vascular invasion by the neoplastic cellular population, thus contributing to the relative benignity of this form of Hodgkin's disease.

    Description / Table of Contents: Summary The clinical, pathologic, and immunologic features unique to Hodgkin's disease can be explained by the following hypothesis. A viral transformation of a lymph node cell leads to proliferation of tumor cells and the generation of an immune response consisting of lymphokine production, B cell activation and concomitant suppression of further T cell activation, but ineffective cellular cytotoxicity against the tumor cells. The result of this interaction would be chronic infiltration around the transformed cells, increased immunoglobulin synthesis, and anergy. Failure to destroy the target cells would result in chronicity of these features and progressive disease.
    Notes: Zusammenfassung Das Zustandekommen der klinischen, pathologischen und immunologischen Merkmale, die für den Morbus Hodgkin charakteristisch sind, könnte durch die folgende Hypothese erklärt werden: Eine lymphatische Zelle wird durch ein Virus transformiert und proliferiert als „Tumorzelle“. Die resultierende Immunantwort ist gekennzeichnet durch Lymphokinproduktion, B-Zellaktivierung, Suppression einer T-Zellaktivierung, aber ineffektive zelluläre Zytotoxizität gegenüber den Tumorzellen. Eine derartige Immunantwort könnte die chronische, reaktive Zellinfiltration in Nachbarschaft der Tumorzellen, eine gesteigerte Immunglobulin-Synthese und Anergie erklären. Gleichzeitig könnte die mangelhafte Zerstörung der Tumorzellen den chronisch fortschreitenden Charakter der Erkrankung erklären.
