RESUMO
The development of desmoid tumors in patients with Gardner's syndrome may produce ureteral findings on excretory urogram which, by themselves, are indistinguishable from other causes of retroperitoneal fibrosis.

The lesions of herpes zoster of the colon were observed in three cases. Small polygonal mucosal blebs or small ulcerations involving a short segment of the colon and appearing in a reasonable time relationship with the cutaneous manifestations either in a corresponding or noncorresponding dermatome should enable diagnosis of this unusual condition. Recognition of this entity in the presence of these skin lesions should be obvious and therefore helpful in avoiding more aggressive and invasive diagnostic procedures.

Because endoscopy and gastric cytology lack specificity, radiographic evaluation is still the most reliable means of diagnosing gastric lymphoma preoperatively. A retrospective analysis indicates that if careful attention is paid to the radiologic features, gastric lymphoma can be distinguished from gastric carcinoma in most of cases. The radiographic findings of a long segment of involvement, multiplicity of radiographic pattern, and diffuse infiltration consisting of concentric abnormal folds without significant narrowing of the lumen are characteristic of the non-Hodgkin's lymphoma.

Abdominal masses, "desmoid tumors," occur in approximately 4% of patients with Gardner's Syndrome, usually 1--3 years after total colectomy. Histologic sections usually resemble those of an infiltrating fibrous tumour, a desmoid lesion. The radiographic pattern may be similar to any diffuse abdominal retroperitoneal tumor, metastatic disease, lymphoma, or possibly retractile mesenteritis. The clinical setting usually differentiates these entities.

Metastatic disease involving the stomach is an unusual and difficult clinical problem. A review of 1010 autopsies of patients with cancer disclosed 17 cases of gastric metastases (an incidence of 1.7%), with breast cancer, lung cancer, and melanoma being the most frequent primaries. The clinical manifestations of epigastric pain, melena, and anemia are nonspecific, necessitating radiographic examination of the gastrointestinal tract. The radiographic findings are usually sufficient to suggest the diagnosis.
