[Lymphogranulomatosis of the thymus gland ("granulomatous thymoma")]

Thirteen tumors of questionable genesis located in the thymus were studied. The microscopical structure of these tumors was identical to lymphogranulomatosis of other localization. Reactive proliferation of the thymic epithelium and cyst formation are characteristic of lymphogranulomatosis primarily developing in the thymus. The disease was not "granulomatous thymoma" since giant multinuclear cells by their structural characteristics corresponded to reticular elemens and the epithelial component was absent in extrathoracal formations.
