Thyroid papillary adenocarcinoma in a woman with Peutz-Jeghers syndrome

Abstract

We present a rare case of Peutz-Jeghers(P-J) syndrome in a 29-year-old woman who developed adenocarcinoma of the thyroid and polyps in the gastrointestinal tract. Polyps removed from the stomach, colon and ileum showed features typical of hamartomas. Histological examination indicated that the tumor resected from the right lobe of the thyroid was a papillary adenocarcinoma. This appears to be the first precise report of a P-J syndrome associated with thyroid carcinoma. This case adds an example of predisposition of P-J syndrome to extra-intestinal malignancy and indicates the importance of long-term observation of malignancy.
