Linitis plastica of the colon is an uncommon presentation of primary colorectal cancer. This entity of colorectal cancer is characterized by a diffuse infiltrating tumor with desmoplastic reaction and poor prognosis. Although widespread infiltration is the main feature of linitis plastica, the tumor extending to more than 2 segments of the colon is uncommon. We report a case of primary linitis plastica involving the entire colon, ileum and appendix. The clinical characteristics are discussed with a review of literatures.

Patients with neurofibromatosis-1 (NF-1) have increased susceptibility to a variety of malignancies. Here, we document a rare case of two separated ileal adenocarcinomas in NF-1. The adenocarcinomas were surrounded by a diffuse tubular adenomatous lesion of the mucosa, and ganglion cells were scattered in the NF background. We found this case meaningful for several reasons: two separated adenocarcinomas arising in an unusual ileal segment, the association with precancerous tubular adenoma, and the presence of ganglion cells, which suggests ganglioneuromatosis in NF-1.

Malignant melanoma is the most common metastatic tumor of the gastrointestinal tract and can present with fairly common constitutional symptoms. A 36-yr-old woman was found to have a secondary malignant melanoma in the terminal ileum with profuse aneurysmal dilatation, which is not the typical presentation of the malignant melanoma in the small intestine. Radiologic studies revealed a large tumor involving the distal ileum with aneurysmal dilatations having afferent and efferent loops, which needed to be differentiated from malignant lymphoma and other gastrointestinal tumors. Exploratory laparotomy was done, and we found a huge mass with plentiful aneurysmal dilatations; much the same of the findings from the previous studies. Segmental resection with the surrounding omentum was done followed by end-to-end anastomosis between both ends of the remaining ileum. She had been free from any evidence of the local or systemic recurrence for one year after the completion of eighteen months of the subcutaneous interferon treatment; postoperatively however, the occurrence of metastatic mass at the right axilla rendered us from complete resection due to severe penetration into the vital nerves and vessels in the axilla.

Primary small intestinal lymphoma is relatively uncommon. Small bowel tumors are difficult to diagnose, because they are usually asymptomatic in the initial phase, and they are not easily detected by traditional methods of investigating the small intestine. This case shows a successfully detected and treated gastrointestinal bleeding from rare ileal mucosa-associated lymphoid tissue lymphoma, using double balloon endoscopy.

Crohn's disease and ulcerative colitis are well known risk factors of intestinal cancer in relation to the extent and duration of disease. Rarely, small bowel cancer can develop after a longstanding inflammation of Crohn's disease with a relatively higher incidence than the general population. Signet ring cell carcinoma is a rare condition among intestinal cancers, and the diagnosis or detection is more difficult if the cancer originates from the small bowel. We report a case of a 30-year old female in whom signet ring cell carcinoma of ileum was diagnosed after a 15-year history of Crohn's disease.

We report a rare case of giant mesenteric lipoma presenting with colicky abdominal pain. A 29-yr-old woman underwent laparoscopic resection for a giant mesenteric lipoma causing compression of the ileal loop. The resected ileal segment was encased by a giant fatty tissue, and normal mucosal fold patterns of the resected ileum were effaced by the mass. Microscopically, the mass was characterized by homogenous mature adipose tissue without cellular atypia, which was compatible with the diagnosis of a mesenteric lipoma. Despite the benign nature of this tumor, total excision with or without the affected intestinal loop should be considered if intestinal symptoms such as abdominal pain are present.

Gastrointestinal stromal tumor (GIST) is an uncommon mesenchymal tumor of the gastrointestinal tract and is generally located in the stomach and small intestine. They usually present with abdominal pain, gastrointestinal bleeding, and palpable mass. Some patients present with rare symptoms that are more common in malignant GIST. Malignant GIST combined with a liver abscess has not been reported yet in the literatures. We report a case of 67-year-old woman who suffered from liver abscess combined by malignant GIST with central necrosis and fistula in the ileum. She complained of fever, chills, and abdominal pain. Abdominal CT scan showed huge liver abscess and ileal mass with air pocket. Small bowel series showed contrast material filling into the ileal GIST mass. An operation was performed and the final diagnosis was malignant GIST of the ileum with invasion into the sigmoid colon and urinary bladder.
