Thymic Hyperplasia after Lung Transplantation Imitating Posttransplant Lymphoproliferative Disorder

Abstract EN

Thymic hyperplasia is usually associated with the treatment of malignant tumours and is sometimes linked with endocrine diseases.

For the first time, we report a case of thymic hyperplasia in a patient 2 years after bilateral lung transplantation.

Contrast-enhanced chest CT scan was highly suspicious for a posttransplant lymphoma or thymoma.

Therefore, the patient received total thymectomy.

Excised specimens were sent to the Department of Pathology.

Unexpectedly, the histological examination revealed hyperplastic thymic tissue without evidence for a posttransplant lymphoproliferative disorder or malignancy.
