Résumé
Aniskiasis is caused by the accidental infestation of human by larvae of marine mammals found in saltwater fish and squid. The clinical picture may be severe enough to stimulate an acute surgical abdomen. More commonly, colicky pain, diffuse abdominal tenderness, nausea, vomiting, fever, and leukocytosis are seen. Gastroscopically, 2-to 4-cm larvae can be seen penetrating the mucosa. More characteristically, the larvae burrow into the mucosa of the stomach. Here they produce eosinophilic granulomatous tumors with edema, thickening, and induration which may be mistaken for gastric canceer. The pathalogic changes are thought to be the result of a hypersensitivity reaction. We report a case of chronic gastric anisakiasis, which was diagnosed as submucosal tumor with massive bleeding.

Gastric metastasis occurs in about 0.7% to 1.7%, of patients dying of solid tumors of extragastrointestinal origin. Metastatic disease involving the stomach is an unusual and difficult clinical problem and presenting symptoms include nonspecific epigastric pain and melena. In most cases of gastric metastasis, the histologic finding of the gastroscopic biopsy suggests the correct diagnosis. There are only a few reports of gastric metastasis from malignant melanoma. We report a case of malignat melanoma of gastric metastasis, which was diagnosed by gastroscopy.

Familial adenomatous polyposis(FAP) is the most oommon of the polyposis syndromes. It is characterized by multiple colorectal adenoma and a high occurrence rate of associated colonic adenocarcinoma in all untreated cases. FPC is inherited as antosomal dominant trait. During 20 years after diagnosis, adenocarcinoma occurs in more than 50% of patients. Clinically, surgical resection should be advised at the time of diagnosis in almost all cases, and acquainted with the potential risks to their children and advised to seek genetic counselling. we report three cases with familial adenomatous polyposis in family.
