Final diagnoses included one bronchogenic cyst and one combined bronchogenic cyst and thymic hyperplasia. |
A class of lymphocytes, so called because they are derived from the thymus and have been through thymic processing. |
Most of these lesions arise as a consequence of migrational defects during thymic embryogenesis. |
After partial decerebration, the thymic cortical and medullary compartments diminished markedly in size. |
In addition, thymic atrophy occurs secondary to decreased thymic hormone secretion, which leads to decreased T-lymphocyte production. |
Progressive growth of a spontaneous T cell lymphoma, designated as Dalton's lymphoma, causes suppression of immune responses and thymic atrophy. |
