It is characterized by mucocutaneous hyperpigmentation, hamartomatous polyposis, and predisposition to cancer. The aim of the present study was to identify and register patients with Peutz-Jeghers syndrome, describe the disease, and estimate its prevalence in Valencia (Spain). Materials and methodsA print-out of the clinical histories from 10 hospitals was obtained utilizing the ICD-9 code 759.6 from the Minimum Basic Data Set of Hospital Admissions of the Spanish Ministry of Health and Consumer Affairs. ResultsFrom a total of 405 clinical histories found, 15 (9 males and 6 females) fit the diagnostic criteria of Peutz-Jeghers syndrome. Mean age at diagnosis was 13.8 years and mean age at death was 54.2 years. Four males died, all from cancer. The estimated disease prevalence was 0.4/100,000 inhabitants. All the patients presented with anemia and polyps in the small bowel (80% in the duodenum, 66.7% in the ileum, and 40% in the jejunum), 93.3% underwent urgent surgical intervention and presented with intestinal invagination, and 40% of the patients developed cancer at a mean age of 48.5 years. ConclusionThe present study is the first register of patients with Peutz-Jeghers syndrome in Valencia, Spain. The ICD-9 code is nonspecific for rare diseases. The duodenum was the most frequent location for polyps and the majority of cases presented with intestinal invagination, bowel obstruction, and urgent surgical intervention. A large percentage of patients presented with cancer. It would be of interest to review and evaluate the existing surveillance protocols in the Valencian Community. ER -
