Coexisting intrathyroidal parathyroid adenoma and micropapillary carcinoma of the thyroid

Paratiroidler nadiren ektopik lokalizasyonlarda bulunabilir. Ektopik yerleşimli paratiroidlerin büyük çoğunluğu ön mediastende timus içerisinde, arka mediastende, tiroid içerisinde ve nadiren de karotis kılıfında bulunurlar. Diğer ektopik paratiroid görülen yerler perikard, vagus siniri ve mandibula köşesindeki yumuşak dokudur. Paratiroid adenomları ektopik yerleşimli bezlerden de gelişebilir. Bu ektopik yerleşimli paratiroid adenomları primer hiperparatiroidizme de neden olabilir. İntratiroidal paratiroid adenomu ile birlikte tiroid papiller karsinomu görülmesi oldukça nadir bir durumdur. Bu makalede 76 yaşındaki bir kadm hastada mikropapiler tiroid kanseri ile senkron görülen bir intratiroidal paratiroid adenomu olgusu sunulmaktadır.

Tiroid papiller karsinomu ile birlikte görülen bir intratiroidal paratiroid adenomu

Parathyroid glands are occasionally found in an ectopic location. The vast majority of ectopic parathyroid glands are found within the thymus, in the anterior mediastinum, followed by the posterior mediastinum, thyroid and, rarely, the carotid sheath. Other rare sites of ectopy include the pericardium, vagus nerve or the soft tissue adjacent to the angle of the jaw. Parathyroid adenomas can occur in any site containing ectopic parathyroid tissue. Ectopic parathyroid adenomas may also be the cause of primary hyperparathyroidism. The concomitant existence of intrat-hyroidal parathyroid adenoma and papillary carcinoma of the thyroid is exceedingly rare. Here we report a case of intrathyroidal parathyroid adenoma associated with a synchronous micropapillary carcinoma in a 76-year-old female patient.
