-
-
- Cronkhite-Canada Disease is characterized by multiple, benign growths
- (polyps) on the mucosal lining of the intestinal wall, especially in the
- colon, rectum, and stomach, and by changes in ectodermal structures, i.e.,
- hair, skin, fingernails, etc. The disease does not appear to be hereditary.
- It is possible that the ectodermal changes result from malabsorption of
- essential vitamins. Women are affected more often and more severely than
- men, and most patients are elderly. The disorder can cause malnutrition and
- sometimes life-threatening metabolic disturbances.
-
- Symptoms
-
- Cronkhite-Canada Disease appears in middle aged or elderly persons. The
- numerous polyps are found primarily in the stomach and large intestine,
- although they also occur in the small intestine. Patients experience
- diarrhea, abdominal pain, loss of appetite, and sometimes nausea or vomiting.
- Changes in skin and related structures accompany these symptoms. Body hair
- may fall out, the skin becomes brownish on the face, neck, and hands, and the
- toe and fingernails atrophy. There may be swelling in the ankles, lower back
- and pelvis.
-
- The changes in the lining of the intestinal tract can impair absorption
- of nutrients and laboratory tests show reduced protein levels in the blood,
- electrolyte (salt) imbalances, anemia, and the presence of undigested
- proteins and fats in the stool. Thus, the patient may become gradually
- weaker and more susceptible to infections, etc.
-
- Causes
-
- Cronkhite-Canada Disease does not seem to be a hereditary disease. Its
- causes are unknown. Vitamin deficiencies due to malabsorption may cause the
- changes in ectodermal structures.
-
- Affected Population
-
- Cronkhite-Canada Disease affects primarily elderly or middle aged women.
-
- Related Disorders
-
- Cronkhite-Canada Disease is related to several syndromes in which intestinal
- polyposis plays a role. Familial Adenomatous Colon Polyposis is
- characterized by numerous polyps in the large intestine and a high incidence
- of colonic cancer by age 40 if untreated. In Gardner Syndrome, colonic
- polyposis is associated with cysts and tumors in the skull and related
- structures, and extra teeth. In Peutz-Jeghers Syndrome, numerous polyps in
- the stomach and small and large intestines are associated with discoloration
- of the skin and mucous surfaces. In Turcot Syndrome, familial polyposis
- occurs with tumors in the central nervous system.
-
- Therapies: Standard
-
- Surgical removal of polyps may correct malabsorption in Cronkhite-Canada
- Disease. However, they may recur or be too numerous to remove individually.
- If necessary, severely affected parts of the stomach or colon can be removed.
-
- Therapies: Investigational
