Different phenotypes including gynecological cancer in three female patients with Peutz-Jeghers syndrome and mutations in the STK11 gene.
BACKGROUND
Peutz-Jeghers syndrome (PJS), a rare hereditary disorder, is characterized by the occurrence of gastrointestinal hamartomatous polyps associated with mucocutaneous pigmentation. Patients are at an increased cancer risk not only for gastrointestinal but also for extraintestinal neoplasms.


RESULTS
We report on the clinical and molecular findings in 3 young female patients with PJS; 2 of them suffered from severe gynecological cancer. One patient died at the age of 29 years of an incurable mucin-producing cervical adenocarcinoma. Another patient had a papillary serous carcinoma of the ovary. In all patients, we identified corresponding mutations in the STK11 gene, 2 of them novel.


CONCLUSIONS
PJS should be considered in differential diagnosis in young women with gynecological malignancies. Identification of STK11 mutations in patients and their relatives can help to improve the clinical management.
