We report a case of association of a brain tumor with multiple intestinal polyposis (Turcot's syndrome) and offer a critical analysis of the relevant literature with a view to revising the classification of the syndrome in relation to familial multiple polyposis and Gardner's syndrome. For this purpose, we considered only cases of intestinal polyposis associated with a primary neuroepithelial tumor (medulloblastoma, glioma, or glioblastoma) as originally described by Turcot. Differences emerged, depending on the central nervous system tumor type, which suggests that this neoplastic association may be classified as two distinct syndromes.

A nonfamilial case of Turcot syndrome (glioma-polyposis syndrome) is described. A 16-year-old male with no siblings first developed a frontal astrocytoma, and was later found to have colonic polyposis with adenocarcinoma. The family history was negative for the syndrome, but his parents were first cousins.

We report the diagnosis of an adenocarcinoma of the colon in a 12-year-old girl in association with the presence of a small number of adenomatous polyps and a positive family history of a sibling with a central nervous system glioma. These findings implicate Turcot's syndrome as the cause for the development of intestinal and intracranial neoplasms in the two siblings. Since primary adenocarcinoma of the bowel is unusual in children, an underlying predisposing condition should be sought in affected cases.

The reported clinical manifestations of Turcot syndrome were studied to determine whether these corresponded to those of Turcot's original cases. Among the patients with well-documented colonic lesions, the colonic lesions were classified into three groups. First, there was a main group in which colonic lesions had the following characteristics that coincided with those of Turcot's original cases: a low number of polyps (20-100), large polyps over 3 cm in diameter, and complication by colonic cancer during the second or third decades. In the second group, the patients had too few polyps to be diagnosed as polyposis. The third group included patients with numerous colonic polyps similar to those of familial polyposis coli. The recognition of these characteristics of colonic lesions may lead to early detection of glioma in the asymptomatic period.

A case of Turcot syndrome (glioma polyposis) is described in a 22-year-old woman. The patient initially presented with a frontoparietal glioma, and was subsequently found to have segmental colonic polyposis with adenocarcinomatous changes. Her colonic polyposis was nonfamilial.

A case of Turcot's syndrome is described in an 8-year-old girl. Turcot's syndrome is a rare hereditary disease in which malignant glioma of the central nervous system is associated with colonic polyposis. The patient initially presented with a left parietal glioblastoma diagnosed by computed tomography (CT), and was subsequently found to have nonfamilial colonic polyposis.

Tumors of the central nervous system (CNS) are common causes of morbidity and mortality. These tumors can occur sporadically or in individuals with genetic disorders predisposing to cancer development. Such syndromes include neurofibromatosis type 2, neurofibromatosis type 1, Li-Fraumeni syndrome, as well as von Hippel-Lindau disease, tuberous sclerosis, and Turcot syndrome. There may also be familial syndromes resulting in glioma or meningioma alone, but these are not well understood. Development of sporadic gliomas is accompanied by a number of molecular genetic alterations, including activation of dominant oncogenes and inactivation of tumor suppressor genes. Some of these alterations may be associated with progression of gliomas to their most malignant form, glioblastoma multiforme. However, at this time molecular genetic analysis of gliomas does not provide better prognosis than histopathological staging. Recently, experimental treatments of gliomas in rodents, using gene therapy, have been reported. Results of these studies have been promising, and these techniques may represent a future direction for therapy in humans.

We report on a 12-year-old patient with Turcot Syndrome (Glioma polyposis). This patient's case deals with the association between a glioblastoma, anaplastic glioma (WHO Grade III) and colonic adenocarcinoma based on familial polyposis coli. Possible etiology and neurosurgical, clinically important characteristics of this rare syndrome, such as the young age of the patient and the relatively long survival time, will be discussed.

We reported a case of Turcot Syndrome (glioma polyposis) in a 19-year-old woman with nonfamilial polyposis coli and adenocarcinoma of the colon, and grade 3 astrocytoma in the right parietal lobe. The patient was admitted with the complaint of general convulsion after colostomy for polyposis and adenocarcinoma of the colon. CT scans on admission showed a large parietal tumor in the right side. Total removal was performed successfully and histological examination showed astrocytoma grade 3. One year after the operation, the tumor recurred. Conservative treatment failed to improve her condition and she died one year later. Turcot Syndrome (glioma polyposis) is very rare and only 10 cases have been reported in Japan. In this report, the clinical characteristics of this syndrome were discussed.

We investigated clinical manifestations in 124 patients with a possible Turcot's syndrome whose data were taken from documented cases. The cases were subclassified mainly on the bases of the type of familial occurrence and listed in five Tables. We searched for differences in colonic manifestation, histologic type of glioma, mode of inheritance, frequency of parental consanguinity, skin lesions and other accompanying lesions among these five groups. The differences of these clinical findings suggested that glioma-polyposis syndrome should be classified as follows; (1) cases of Turcot's syndrome who had characteristic colonic and brain manifestations, (2) cases of FAP associated with glioma, (3) suspicious cases of glioma-polyposis, and (4) cases other than glioma-polyposis syndrome.
