-
-
- Peutz-Jeghers Syndrome is a hereditary condition characterized by
- multiple, benign growths (polyps) on the mucous lining of the intestinal
- wall, and dark discolorations on the skin and mucous surfaces. Low grade
- malignancies develop in about a fifth of the patients, but the risk of cancer
- is much lower in this syndrome than in the familial colonic polyposes.
-
- Symptoms
-
- Peutz-Jeghers Syndrome appears between 10 and 30 years of age, although the
- characteristic discolorations are present from birth. These freckles are
- found around the lips, inside the mouth on the mucosal lining of the cheeks,
- and on the fingers, palms of the hands, forearms, toes, and around the naval.
- They may coalesce, intensify, or fade, especially around puberty.
-
- Polyps occur in the small intestine, and occasionally in the stomach or
- large intestine (colon). Patients can experience severe, recurrent pain that
- disappears with massage, physical manipulation, or contorting the body. The
- intestine has a tendency to prolapse into itself like a telescope
- (intussusception). The "stomach may growl" frequently, and there may be
- considerable abdominal discomfort. Intestinal bleeding occurs, often
- sufficiently to cause anemia, but is commonly only discovered in the stool by
- laboratory testing.
-
- Untreated patients may develop intestinal malignancies by their early
- forties. Intussusception, or telescoping, can cause serious complications
- such as intestinal obstruction and gangrene (necrosis or death of the tissue)
- requiring surgery. Intestinal bleeding can also become quite severe.
-
- Causes
-
- Peutz-Jeghers Syndrome is inherited through an autosomal dominant mechanism.
-
- (Human traits including the classic genetic diseases, are the product of the
- interaction of two genes for that condition, one received from the father and
- one from the mother. In dominant disorders, a single copy of the disease
- gene (received from either the mother or father) will be expressed
- "dominating" the normal gene and resulting in appearance of the disease. The
- risk of transmitting the disorder from affected parent to offspring is 50%
- for each pregnancy regardless of the sex of the resulting child.)
-
- Related Disorders
-
- Peutz-Jeghers Syndrome is related to several syndromes in which familial
- polyposis plays a role. In familial adenomatous colon polyposis, numerous
- polyps develop in the large intestine and are associated with a very high
- incidence of colonic cancer if untreated. In Gardener syndrome, polyposis is
- associated with cysts and tumors in the skull and related structures, and
- extra teeth. The Canada-Cronkhite syndrome combines familial polyposis with
- abnormalities of the structures derived from the embryonic ectodermal layer.
- In Turcot syndrome, familial polyposis occurs with tumors in the central
- nervous system.
-
- Therapies: Standard
-
- Large individual polyps or particularly heavily affected sections of the
- intestine can be removed surgically in patients with Peutz-Jegher Syndrome.
- If complications such as intussusception or intestinal gangrene develop, the
- involved intestine must also be resected.
-
- The gastrointestinal tract should be X-rayed periodically to detect
- changes in size and number of polyps. This should be done periodically from
- childhood through adolescence.
-
- Therapies: Investigational
