RESUMO
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.

We present a case of hepatic myelolipoma that was treated by performing a right hepatic lobectomy. These tumors are very uncommon and present great problems for the pre-operative diagnostic evaluation. Currently, the diagnosis is essentially histopathological with a definitive diagnosis being made by immunocytochemical staining. We have found no reports on this type of tumor in the Spanish literature; a review of the published cases confirms our observations and conclusions regarding hepatic myelolipoma.
