A case of perforated small bowel adenocarcinoma presenting as first symptom of Crohn's disease is reported in a 53 years old male patient with abdominal pain and alteration of bowel habits. Endoscopic bioptical sampling demonstrated a Crohn's disease in active stage. The patient underwent medical therapy with resolution of the complained symptomatology; 20 days after discharge the patients is rehospitalized for acute abdomen. A narrowing perforated neoplasia in terminal ileum was discovered at laparotomy. Diffuse peritonitis and metastatic peritoneal implantations were also revealed. An ileocolic resection is performed with ileo-transverse colon anastomosis. The patient dies 4 months later for advanced disease.

A case of primary small bowel adenocarcinoma is reported because of the rarity of this malignancy. Interestingly, the location of the tumour was in jejunum, instead of the most common site in duodenum. The clinical presentation was anemia, with positive fecal blood test, under antiaggregant platelet treatment for coronary heart disease, initially related to endoscopic evidence of erosive gastroduodenitis. The exacerbation of gastrointestinal bleeding during proton pump inhibitors therapy and the recurrence of abdominal pain caused careful investigation. The source of the obscure gastrointestinal bleeding had been achieved by wireless capsule endoscopy, because of not diagnostic findings of conventional upper endoscopy control, colonscopy, double contrast enteroclysis and selective arteriography. The primary definitive therapy was a radical resection of the jejunal neoplastic loop, important prognostic factor.

A 50-year-old woman was admitted to our hospital because of abdominal pain and vomiting. Ileus with ulcerated jejunal tumor was diagnosed and biopsy revealed adenocarcinoma. Because her serum level of DUPAN-2 was high, she was examined by PET scan, which revealed that she had a left ovarian mass in addition to the jejunal tumor. Surgical resection was performed: both tumors were adenocarcinoma, but the ovarian tumor was considered to be metastatic clinically and histologically. Immunostaining for DUPAN-2 was positive in the both tumors. The serum level of DUPAN-2 returned to normal after the surgery, and has been within normal limits for about 3 years without any additional therapy. This case shows a possible relation between small bowel adenocarcinoma and DUPAN-2.

Usually, celiac disease has a benign course, though the overall morbidity and mortality have increased. Treatment with a gluten-free diet restores the damaged intestinal mucosa. In rare cases a small bowel adenocarcinoma develops. Unfortunately, the clinical presentation is not always recognized and prognosis is bad. We present a 69-year-old man with a history of dermatitis herpetiformis who presented to our tertiary center for a second opinion for a suspected gastric motility disorder. This diagnosis was based on the combination of upper abdominal pain for over 2 years and repetitive episodes of vomiting. Immediately after referral, celiac disease was diagnosed and a gluten-free diet was started. In the next half year of follow-up, additional anemia and weight loss developed and eventually a small bowel adenocarcinoma was diagnosed. Revision of a small bowel follow-through, which had been performed 2 years earlier, showed that the tube had been positioned just distal from the process. Therefore, this diagnosis had not been made at that time. Unfortunately, curative therapy was not possible and the patient died a few months later. In conclusion, all patients with dermatitis herpetiformis have a gluten-sensitive enteropathy and should be treated with a gluten-free diet. Next to this it is important to notice that patients with celiac disease have an increased risk of developing a small bowel malignancy. Unexplained upper abdominal pain, weight loss and anemia should lead to additional investigations to exclude a small bowel malignancy in these patients. At last, the diagnosis of a small bowel carcinoma is difficult. Together with the radiologist, the optimal techniques for visualization of this malignancy should be considered.

A 40-year-old male, diagnosed with mild Crohn's disease (CD) 11 years ago but with no prior abdominal surgeries, was diagnosed with a small bowel stricture, due to ongoing abdominal pain and intolerance of enteral diet, and referred for surgical treatment. Exploratory laparoscopy revealed a white solid mass causing a near total jejunal obstruction with significant proximal dilatation. An adjacent small node was sampled for frozen biopsy, revealing a lymph node infiltrated with adenocarcinoma. Laparoscopic assisted small bowel resection and appendectomy were carried out. Final pathological results supported the initial report of diffuse small bowel adenocarcinoma. In conclusion, once a small bowel stricture associated with CD is suspected, rapid action should be considered to avoid late diagnosis of a neoplasia.

The aim of the study was to describe and analyze the clinicopathological features and diagnosis of Chinese patients with small intestine primary malignant tumors and to explore the best therapy to small bowel adenocarcinoma (SBA). More than 26,000 patients with digestive tract malignant tumors received treatment in PLA hospital from 2000 to 2011, and among them, there were 887 patients who had small intestine primary malignant tumors, and 666 of 887 patients had the completed basic clinical documents. We retrospectively analyzed the correlation between clinical and pathological features of the 666 patients and analyzed the survival and prognosis of 173 SBA patients with follow-up data. Both the number of patients with primary malignant tumors of the small intestine and the number of patients who received chemotherapy showed an increasing trend. The ratio of male to female was 1.58:1. The male patients significantly exceed the female patients with tumors of non-ampullary duodenum, jejunum and duodenal ampulla; and most of the patients are over 60 years of age. For patients burdened with either of the pathological types of tumors, the males exceeded the females, but there was no significant difference. Abdominal pain was the main clinical manifestation for patients with tumors of non-ampullary duodenum, jejunum and ileum, and the most common clinical manifestations were jaundice and abdominal pain for patients with ampullary duodenal tumors, adenocarcinoma, neuroendocrine tumors and sarcoma. In addition, patients with stromal tumors were prone to gastrointestinal bleeding. Gastrointestinal endoscopy was the most common examinational procedure. Patients under 60 years of age were prone to surgery and chemotherapy after surgery, and patients over 60 years of age were prone to supportive treatment and chemotherapy without surgery. The medium overall survival of patients who received surgery without chemotherapy, chemotherapy after surgery, chemotherapy without surgery and supportive treatment were 40.0, 35.0, 9.0 and 7.5 months, respectively. For the 173 SBA patients with follow-up data, treatment, age and distant metastasis were important prognostic factors; 149 of 173 SBA patients received only surgery, and the depth of tumor invasion, lymph node metastasis and surgical approach were important prognostic factors. Adjuvant chemotherapy had not provided significant benefit to prolong OS in patients with adenocarcinoma. The incidence of small intestine primary malignant tumors is very low, and it is difficult to diagnose. The patients should be aggressively treated and regularly followed up with related clinical and pathological features. Currently, surgery is the most effective treatment, and the role of chemotherapy needs further large-scale clinical studies.

Primary small intestinal cancer is very rare. We experienced 4 cases from 2001 to 2013. Case 1: A 46-year-old man presented with abdominal pain and melena. Computed tomography (CT) revealed a tumor in the jejunum. We performed partial resection and lymph node dissection. The histological examination confirmed the diagnosis of moderately differentiated adenocarcinoma, SEN0H0P0M0. He has been recurrence-free for 13 years. Case 2: An 84-year-old woman presented with abdominal pain and vomiting. Gastroscopy showed a tumor in the upper jejunum, and she was diagnosed with adenocarcinoma. Postoperative diagnosis was SEN0H0P0M0. She has been alive for 7 years. Case 3: A 66-year-old woman presented with epigastric discomfort and back pain. Examinations confirmed poorly differentiated small intestinal adenocarcinoma with multiple liver and lymph node metastases. She refused chemotherapy and died 1 month later. Case 4: A 60-year-old man presented with abdominal pain and vomiting. CT revealed a tumor in the jejunum. Gastroscopic biopsy led to a diagnosis of poorly differentiated adenocarcinoma. We performed partial resection but there was extensive lymph node metastasis and peritoneal dissemination (cSIN2H0P3M1) so curative resection was impossible. Two courses of chemotherapy with S-1 and CDDP were administered. However, chemotherapy was not effective. He died 3.5 months after the first operation. Based on 2 of our cases, the prognosis for primary small intestine adenocarcinoma with lymph node metastasis or peritoneal dissemination was poor, with survival of less than 6 months. However, N0 cases without peritoneal dissemination can achieve long-term survival with curative resection. We report these cases with a review of previously reported cases in the literature.

Adult intussusception and small bowel adenocarcinoma are rarely encountered together. Intussusception should be considered in the differential diagnosis of adult patients presenting with abdominal pain, especially those with unremitting symptoms. Concomitant anaemia should lower the threshold for suspicion of underlying malignancy. Jejunal adenocarcinoma represents a rare, but possible aetiology.

Celiac disease is a chronic immune-mediated enteropathy in which dietary gluten induces an inflammatory reaction predominantly in the duodenum. Celiac disease is known to be associated with benign small bowel thickening and reactive lymphadenopathy that often regresses after the institution of a gluten-free diet. A 66-year-old male patient with celiac disease presented with abdominal pain and diarrheal illness. Computerized tomography of the abdomen revealed a duodenal mass. Endoscopic ultrasound-guided fine needle aspiration of the mass revealed bizarre stromal cells which represent a nonspecific tissue reaction to inflammation. This inflammatory mass regressed after the institution of a gluten-free diet. This case report describes a unique presentation of celiac disease in the form of a granulomatous self-regressing mass. Also, this is the first reported case of bizarre stromal cells found in association with celiac disease. In addition to lymphoma and small bowel adenocarcinoma, celiac disease can present with a benign inflammatory mass, which should be serially monitored for resolution with a gluten-free diet.

BACKGROUND Primary small bowel cancer is a rare malignancy; the common histopathological types are carcinoid and adenocarcinoma. Inflammatory bowel diseases and familial adenomatous polyposis are known risk factors for small bowel cancer. Additionally, cases of surgery-induced small bowel adenocarcinoma are sometimes reported after ileostomy. CASE REPORT A 84-year-old woman, who had undergone ileotransversostomy for intestinal obstruction due to postoperative adhesion following appendectomy at the age of 31 years, was referred to our hospital for further examination after experiencing abdominal pain in the right lower quadrant for 2 weeks. Laboratory data showed elevated serum levels of carcinoembryonic antigen (CEA, 102.9 ng/ml) and carbohydrate antigen 19-9 (CA19-9, 104 U/ml). Enhanced computed tomography (CT) revealed a 10-cm mass in the terminal ileum and a distention of the ileum and colon in the blind loop, with retention of feces. The patient was suspected of having ileal cancer by preoperative examination; therefore, right hemicolectomy with en bloc resection was performed. The tumor was histopathologically diagnosed as a well-differentiated and mucinous adenocarcinoma of the ileum. At over 12 months after surgery, tumor recurrence had not been observed. CONCLUSIONS Difficulties in diagnosis can cause delays in treatment and lead to poor prognosis, mainly because tumors in the small bowel rarely cause clinical symptoms. Adenocarcinoma of the ileum should be considered in postoperative patients with ileotransversostomy.
