Overview
Peutz-Jeghers syndrome (PJS) is a disorder in which growths called polyps form in the intestines. It is passed down through families (inherited). A person with PJS has a high risk of developing certain cancers.
What are the symptoms of Peutz-Jeghers syndrome?
Symptoms of PJS are:
- Brownish or bluish-gray spots on the lips, gums, inner lining of the mouth, and skin
- Clubbed fingers or toes
- Cramping pain in the belly area
- Dark freckles on and around the lips of a newborn
- Blood in the stool that can be seen with the naked eye (sometimes)
- Vomiting
What causes Peutz-Jeghers syndrome?
- It is unknown how many people are affected by PJS. However, the National Institutes of Health estimates that it affects about 1 in 25,000 to 300,000 births.
- There are 2 types of PJS:
- Familial PJS may be due to a mutation in a gene called STK11. The genetic defect can be inherited through families as an autosomal dominant trait. That means if 1 of your parents has this type of PJS, you have a 50% chance of inheriting the gene and having the disease.
- Sporadic PJS is not passed down through families and appears unrelated to an STK11 gene mutation.
Who is at highest risk?
When to seek urgent medical care?
Diagnosis
- The polyps develop mainly in the small intestine, but also in the large intestine (colon). An exam of the colon called a colonoscopy will show colon polyps. The small intestine is evaluated in 2 ways. One is a barium x-ray (small bowel series).
- The other is a capsule endoscopy, in which a small camera is swallowed and then takes many pictures as it travels through the small intestine.
Additional exams may show:
- Part of the intestine folded in on itself (intussusception)
- Benign (noncancerous) tumors in the ear
Laboratory tests may include:
- Complete blood count -- may reveal anemia
- Genetic testing
- Stool guaiac, to look for blood in stool
- Total iron-binding capacity (TIBC) -- may be linked with iron-deficiency anemia
