Gardner, 1951

DefinitionThis section has been translated automatically.

Gardner syndrome is a severe form of familial adenomatous polyposis (FAP). Both syndromes are caused by a mutation in the tumor suppressor gene APC. The different phenotypes are explained by the size of the gene and the different location and type of mutation. The mutation variant "Gardner syndrome" is characterized by multiple adenomas in the colon and rectum as well as by striking extraintestinal features such as osteomas and multiple gu-like skin and soft tissue tumors. Colonic polyposis in Gardner syndrome, as in familial adenomatous polyposis, is considered an obligate precancerous condition with a high risk of degeneration beginning at the age of 15.

Dermatologically, Gardner syndrome may present with the following symptoms:

Occurrence/EpidemiologyThis section has been translated automatically.

Incidence: 1/8,300-1/16,000 live births.

EtiopathogenesisThis section has been translated automatically.

In approximately 80% of patients autosomal-dominant inherited, in approximately 20% of cases spontaneous, mutations of the APC gene(adenomatous polyposis coli gene; gene locus: 5q21-q22), which functions as a suppressor gene and belongs to the family of proto-oncogenes. Consequences are the interruption of signal transduction for the normal development of intestinal epithelia and the expression of intestinal polyps.

ManifestationThis section has been translated automatically.

Occurs equally frequently in both sexes.

Clinical featuresThis section has been translated automatically.

Skin lesions and bone abnormalities often manifest before the development of intestinal polyps. Cutaneous epidermal cysts develop in 35%, osteomas in 80% of patients with GS.

Extracutaneous manifestations: Osteomas in the skeletal system mainly in the mandible, cranial dome, long bones, ribs and pelvic bones. Furthermore: retroperitoneal desmoid tumors, hypertrophy of the retinal pigment epithelium (CHRPE).

The main medical problem of GS is premalignant intestinal polyposis mainly in the colon. Sporadically, polyps also occur throughout the small intestine.

Differential diagnosisThis section has been translated automatically.

Complication(s)This section has been translated automatically.

The risk of developing colon cancer is close to 100% (adenocarcinoma).

TherapyThis section has been translated automatically.

Monitoring and, if necessary, polypectomy with histological preparation by gastroenterologists. Treatment of the skin changes, see there.
