Malignant Transformation of Nodular Hyperplasia in the Thyroid: A Case Report

ABSTRACT

Thyroid carcinogenesis is traditionally thought to originate 'de novo'. However, it is debatable whether a malignant transformation can possibly arise from a benign thyroid nodule, as suggested for the malignant transformation of a thyroid adenoma. To the best of our knowledge, no studies have been performed addressing the malignant transformation of nodular hyperplasia in the thyroid gland. Here, we report a case of nodular hyperplasia with focally malignant degeneration.
