[Hyperparathyroidism associated with thyroid disease. Retrospective study of 15 patients treated in 11 years].

The association of hyperparathyroidism with thyroid pathology previous to surgery is not very frequent in our cases, almost a 15%, but it means another difficulty for the diagnostic and treatment. Between 1991 and 2001 we have studied and operated 15 patients with this clinic association. 14 were female and only 1 male with a range age of 59 years old. We studied the type of hyperparathyroidism, personal history, clinic, type of thyroid pathology associated, complementary explorations, type of surgery, anatomopathology evolution, and hospital stay. We have done 12 adenoma resections, 1 subtotal parathyroidectomy, 2 total thyroidectomies and 5 hemithyroidectomies. Only in one patient the anatomopathology was informed as a thyroid carcinoma associated to a parathyroid adenoma, being the other patients benign pathologies. We did literaturer revision on this association. We believe that in all patients with a thyroid pathology we should an associated hyperparathyroidism and vice versa.
