Familial polyposis of the colon. A four-decade follow-up

Turcot syndrome in an elderly adult

A 67-year-old woman presented with hematochezia and an episode of transient expressive dysphasia. She was found to have multiple colonic polyps with adenocarcinomatous changes. Computed tomography brain scan and computed tomography-guided biopsy revealed a left frontoparietal glioblastoma multiforme. This case illustrates the rare presentation of Turcot syndrome-a hereditary colorectal polyposis syndrome-in an older adult.

Upper gastrointestinal pathology in familial adenomatous polyposis: results from a prospective study of 102 patients

Multiple gastric and duodenal biopsy specimens from 102 asymptomatic patients with familial adenomatous polyposis, taken during a prospective endoscopic screening programme were examined. One hundred patients had microscopic gastroduodenal pathology, often in the absence of macroscopic lesions. Adenomas were found in 94 patients in the duodenum, in the second and third parts. Hyperplasia of villous and crypt epithelium was also seen, sometimes in the absence of adenomas: this may be a precursor of neoplastic change. In the stomach fundic gland polyps were the commonest abnormality, seen microscopically in 44 patients. Chronic antral gastritis was common in patients without fundic polyps. Gastric adenomas were present in six patients, all of whom also had duodenal adenomas. If duodenal adenomas in familial adenomatous polyposis have a similar malignant potential to those in the colorectum sequential endoscopy and biopsy are necessary to detect cancer in these patients.

Turcot's syndrome. A review

Turcot's syndrome represents the association between familial multiple polyposis coli and neural tumors. The syndrome is reviewed with reference to genetics, colonic and central nervous system manifestations. This evidence suggests that Turcot's syndrome represents one manifestation of the pleiotropic autosomal dominant gene responsible for familial polyposis coli and the associated extracolonic manifestations of Gardner's syndrome. A diagnosis of Turcot's syndrome should be restricted to those patients with familial polyposis coli associated with gliomas or medulloblastomas. A further case is presented that is believed to be the first report of such a case in the United Kingdom.

Hepatocellular and gastric carcinoma associated with familial polyposis coli

A case of familial polyposis coli in association with hepatocellular and gastric carcinoma is reported. No similar case has ever been documented in the world literature. This may be surprising as it is well known that familial polyposis has a potent oncogenicity not only in the colon but also in extracolonic organs.

The use of indomethacin, sulindac, and tamoxifen for the treatment of desmoid tumors associated with familial polyposis

Seven familial polyposis patients with desmoid tumors were treated with indomethacin, sulindac, or tamoxifen either as single agents or in combination. Serial computed tomographic (CT) scan examination was employed for objective measurement of tumor size since physical examination alone was an inaccurate means to evaluate intraabdominal and retroperitoneal desmoids. Only one patient with minimal tumor burden demonstrated a favorable response with complete resolution of an abdominal wall desmoid.

Excision of multiple epidermal facial cysts in Gardner's syndrome

A rhytidectomy incision is recommended to excise multiple facial epidermal cysts in patients with Gardner's syndrome. The advantage of this approach is that it permits excision of excess skin over the cyst with esthetically pleasing hidden scars. The alternative to this procedure, a separate incision over each cyst, results in disfiguring and conspicuous scars.

Biliary involvement in familial adenomatosis coli

Two patients with polypoid bile duct tumors associated with familial adenomatosis coli are presented. A jaundiced man, aged 63, had polypoid masses identified as adenocarcinoma in the common and hepatic ducts. The other patient, a 38-year-old woman undergoing surgery for duodenal adenomas, had a solitary benign adenoma of the distal common duct in addition to duodenal adenocarcinoma. Only one earlier report of bile duct polyps could be found in association with familial adenomatosis. These cases support the view that familial gastrointestinal adenomatosis is a systemic disease, which is not restricted to the colon and rectum.

Upper gastrointestinal tract polyps in familial adenomatosis coli

Upper gastrointestinal tract polyps were sought prospectively using endoscopy and biopsy in 34 patients with familial adenomatosis coli belonging to 18 unrelated families. Gastric and/or duodenal polyps, usually small and multiple, occurred in 28 patients (82%). Histologically verified extracolonic adenomas were present in 19 patients (56%). Gastric adenomas, all in the antrum, and duodenal adenomas occurred in four (12%) and 16 (48%) patients, respectively. In one patient, a duodenal adenocarcinoma and a bile duct adenoma were also found, and one patient had an adenocarcinoma of the bile ducts. Multiple non-neoplastic polyps were found in 19 patients (56%), most often in the stomach and also in the duodenum in 12 patients; they co-existed often with adenomas. In addition, there were nine patients with ileal polyps, most of them showing lymphoid hyperplasia but also one with adenomas. It is suggested that familial adenomatosis affects the whole gastrointestinal tract, not only the colon and rectum as believed earlier. Although upper gastrointestinal tract adenomas are not as consistent and multiple as those in the colon, and probably do not require prophylactic surgery, regular lifelong endoscopic follow up is warranted because of obviously increased cancer risk.

What can experimental colorectal cancer tell us about colorectal cancer in man?

From a survey of the etiology of colorectal cancer, consideration of the basic pathologic characteristics of ulcerative colitis and familial polyposis of the colon suggests that they might be sister diseases. Similarities in the primary and secondary target organs and in fecal steroid metabolism might be more than coincidental. Thus, it would seem reasonable to pay particular attention to several groups of patients who are receiving therapy or have had operations that alter bile acid and/or cholesterol metabolism: 1) patients who have had jejunoileal bypass procedures for morbid obesity or hypercholesterolemia, 2) patients taking cholestyramine and/or other anti-hyperlipidemic agents, 3) patients receiving chenodeoxycholic therapy to dissolve gallstones, 4) patients taking the birth control pill, and 5) young patients who have had a cholecystectomy. Proponents of such therapy and physicians treating patients who develop colonic cancer or polypoid disease after having had such therapy are encouraged to provide accurate reports.

Clinical and roentgen features of the intestinal polyposis syndromes

The intestinal polyposis syndromes represent a challenging diagnostic problem for the radiologist. These syndromes include: familial multiple polyposis, Gardner's, Peutz-Jeghers, Turcot's, Cronkhite-Canada and juvenile polyposis. The polyposis syndromes can usually be differentiated from one another on the basis of the clinical history, examination of the mucocutaneous tissues and roentgen findings. Numerous other conditions, however, may mimmic a polyposis syndrome, and must be considered in the differential diagnosis.

Desmoid tumors of the abdominal wall

Four cases of desmiod tumors of the anterior abdominal wall recently treated at the University of Chicago Hospitals and Clinics are presented. From our experience we conclude: 1. Inadequate excision of desmoid tumors results in local recurrence. 2. Adequate excision of desmoid tumors ot the abdominal wall sometimes necessitates creation of an abdominal wall defect too large for primary closure. 3. Marlex mesh has been used successfully in reconstruction of the abdominal wall following adequate excision of desmoid tumors. 4. One patient (Case 4) with an abdominal wall desmoid tumor associated with familial polypisis and mesenteric fibromatosis has benefited greatly following wide excision of abdominal wall and reconstriction using Marlex mesh, despite the fact that the mesenteric fibrous tumor was unresectable.

Hereditary polypoid diseases of the gastrointestinal tract: a working classification

Almost all published cases of hereditary intestinal polypoid diseases can be meaningfully classified into a relatively few distinct syndromes including familial polyposis of the colon, Peutz-Jeghers syndrome, and juvenile polyposis. Familial polyposis is characterized by the development of numerous adenomatous polyps of the colon and subsequent development of colorectal carcinoma in nearly all patients. Extracolonic manifestations are common but do not influence the premalignant nature of this syndrome. Peutz-Jeghers syndrome is identifiable by a combination of circumoral melanin pigmentation and hamartomatous polyps. These polypoid lesions have an unusually wide distribution and may occur in the respiratory, gastrointestinal, or genitourinary tract. There is a small but definite increased incidence of gastrointestinal cancer in these patients. Juvenile polyposis presents a more variable spectrum. In one form there is extensive intestinal involvement leading to diarrhea, inanition, and increased susceptibility to infection. Another form is limited to the colon and easily confused with familial polyposis. With the third form, there is involvement of the stomach, intestines, and colon, which makes it easily mistaken for the Peutz-Jeghers syndrome.
