[Resorbing granulomatous process at the contact with the corpuscles of Hassall. Histopathologic aspects]

A histopathologic study of the thymus in human allowed in 14 cases to give evidence of a granulomatous process with macrophages and multinucleate giant cells. These cells are seen at the contact with the corpuscles of Hassall. They dissociate the structure of the latter and contribute to their disappearance. These resorptive granulomatous phenomena illustrate an ill-known aspect of the dynamism of the corpuscles of Hassall.
