Which thymic condition refers to thymic enlargement that is not due to a tumor?

Explanation:
Thymic enlargement that isn’t a tumor is thymic hyperplasia. It means the thymus has increased in size due to a benign proliferation of thymic tissue and lymphoid elements, not because of a neoplastic growth. This distinguishes it from thymoma and thymic carcinoma, which are tumors of thymic epithelial cells (neoplastic processes). A thymic cyst is a non-tumor cystic lesion, not an actual proliferative enlargement of thymic tissue, so it isn’t the same as hyperplasia.
