"The work of Peutz in 1921 [1] and Jeghers et al. in 1949 [2] led to the definition of the Peutz-Jeghers syndrome (PJS) at a clinical level. The main characteristics are autosomal dominant inheritance, lip pigmentations, gastro-intestinal polyposis and various types of cancer. The identification of the LKB1/STK11 gene in 1998 [3, 4] allowed DNA-based diagnosis of PJS and was the starting point for research into the role of LKB1 in molecular pathways.........."

 ".....Peutz-Jeghers syndrome (MIM:175200; ref. 1) is an autosomal dominantly inherited syndrome characterized by mucocutaneous pigmentation and gastrointestinal polyposis (2). In addition to an elevated risk of gastrointestinal cancers, an increased risk of cancers at other sites, such as breast, ovary, uterus, cervix, lung, and testis, has been described (3–7). Rare tumors have also been attributed to Peutz-Jeghers syndrome, including testicular sex cord and Sertoli cell tumors, leading to sexual precocity and gynecomastia (8–10), ovarian sex cord tumors with annular tubules, and adenoma malignum of the cervix (1, 2, 11, 12)"

Abstract

Peutz-Jeghers syndrome (PJS) is a rare genetic disorder characterized by melanotic macules, gastrointestinal polyps and increased cancer risks. We discuss several common scenarios encountered in the diagnosis and management of PJS patients. If the diagnosis is unclear, all pathological material should be re-evaluated by an expert gastrointestinal pathologist. The PJS discussion email list-serve (patient managed) and the peutz-jeghers.com, geneclinics.org, stk11.com websites are useful resources for patients.

Abstract: Peutz-Jeghers syndrome: a study of long-term surgical morbidity and causes of mortality

"Patients with Peutz-Jeghers syndrome (PJS) require lifelong multidisciplinary care for gastrointestinal polyposis and increased risk of cancer.

...The cause of death was unknown in 4 patients, but was due exclusively to malignancies in all other patients, most commonly due to metastatic gynecologic cancer (5)...."

Correspondence: mTOR Inhibitor Treatment of Pancreatic Cancer in a Patient With Peutz-Jeghers Syndrome

TO THE EDITOR:

"Recently, we successfully used everolimus to
achieve a partial remission in a patient with advanced pancreatic
cancer that was induced by Peutz-Jeghers syndrome (PJS). PJS has
been associated with an increased risk of GI, gynecologic, breast, and
pancreatic cancers. PJS is caused by a tumor-suppressor gene mutation
in the serine threonine kinase gene 11 (STK11, also known as
LKB1 gene), localized on chromosome 19p13.3.1,2 Up to 93% of
patients with PJS develop some form of cancer; 11% to 36% develop
pancreatic carcinoma.3,4......"

BACKGROUND: Peutz-Jeghers syndrome (PJS) is a rare autosomal dominant disorder, and women with this syndrome are at an increased risk of developing intestinal and extraintestinal malignancies including breast and gynecologic malignancies. This case report presents a patient with PJS with a concomitant breast cancer, bilateral stromal tumors with annular tubules of the ovaries, and adenoma malignum of the cervix.
