Overview
Symptoms of Peutz-Jeghers syndrome include rectal bleeding, melena, and weight loss.
History and Symptoms
The risks associated with this syndrome include a strong tendency of developing cancer in multiple sites[1]. While the harmartomatous polyps themselves do not have malignant potential, patients with the syndrome have an increased risk of developing carcinomas of the pancreas, liver, lungs, breast, ovaries, uterus and testicles. The average age of first diagnosis is 23, but the lesions can be identified at birth by an astute pediatrician. Prior to puberty, the mucocutaneous lesions can be found on the palms and soles. Often the first presentation is as a bowel obstruction from an intussusception which is a common cause of mortality; an intussusception is a telescoping of one loop of bowel into another segment. Most of the data regarding this disorder are from selected family lines and thus the risks endured by those families regarding outcomes may not translate completely to the patient without a familial history.
The three main criteria for diagnosis are:
- Family history
- Mucocutaneous lesions causing patches of hyperpigmentation in the mouth and on the hands and feet. The oral pigmentations are the first on the body to appear, and thus play an important part in early diagnosis. Intraorally, they are most frequently seen on the gingiva, hard palate and inside of the cheek. The mucosa of the lower lip is almost invariably involved as well.
- Hamartomatous polyps in the gastrointestinal tract. These are benign polyps with a extraordinarily low potential for malignancy.
Having 2 of the 3 listed criteria indicates a positive diagnosis. The oral findings are consistent with other conditions, such as Addison's disease and McCune-Albright syndrome, and these should be included in the differential diagnosis. Definitive diagnosis requires a histological sample of a polyp.
