Association of a thyrotropin-secreting pituitary adenoma and a thyroid follicular carcinoma
The different factors involved as etiological agents in thyroid cancer have in common long term thyroid follicle stimulation. On this base, a patient with a TSH-producing pituitary adenoma could be at high risk for developing thyroid cancer. A patient consulting for a single thyroid nodule was studied in our unit. He was diagnosed as having a TSH-producing pituitary adenoma and the Thyroid nodule was shown to be a follicular carcinoma following removed. We speculate that elevated TSH levels could have contributed to neoplastic transformation of the thyroid in this patient.
