A rare case of Cushing's disease concurrent with papillary thyroid carcinoma.

BACKGROUND: Although a nodular thyroid disease is higher in patients with pituitary adenoma, concurrent thyroid cancer with pituitary tumor is uncommon. CASE PRESENTATION: We report a young woman with discovered papillary thyroid carcinoma after 1-year transsphenoidal surgery for Cushing's disease. Thyroidectomy was done and patient is well after three years follow-up. CONCLUSION: We suggest the patient with functional pituitary adenoma be evaluated for thyroid tumor.
