Leiomyosarcoma (LMS) of the small intestine is a rare tumor, accounting for about 1% of all malignant mesenchymal lesions in the gastrointestinal tract. Since small bowel tumors are initially asymptomatic and nonspecific, delayed diagnosis and treatment are common. We found that a 44-year-old male patient who came in for lower abdominal pain had partial obstruction in the small bowel. Multiple ascites and ileal tumors involving peritoneal seeding were observed from his abdominal computed tomography. He was diagnosed as epithelioid LMS involving peritoneal transition after surgical resection, and the outpatient department has planned for a conservative therapy with observation. To the best of our knowledge, ileal epithelioid LMS accompanying a huge omental mass, with a size of 18 cm in dimension, and peritoneal seeding has not yet been reported in Korea. We report this rare case with literature review.

Alimentary lymphoma accounts for approximately 5% of neoplasm and diffuse lesion is more common than solitary nodular form in dogs. An eleven year-old male Yorkshire terrier was examined because of nonspecific gastrointestinal symptoms such as anorexia and vomiting for 10 days. An abdominal mass was palpated, which was originated from small intestinal wall in abdominal ultrasonography. Small intestine was obstructed by hypoechoic mass and lost normal layering and measured 24.5m. After fine-needle aspiration, septic peritonitis due to intestinal rupture occurred and emergency surgery was performed. Solitary mass was found in small intestine and diagnosed as alimentary lymphoma through histopathologic examination. Conclusively, abdominal ultrasonouaphy could verify the thickened bowel, loss of wall layering and decrease of motility and percutaneous ultrasound-guided fine-needle aspiration is considered as useful diagnostic technique, especially in nodular form of alimentary lymphoma.

Intussusception is a serious disease where part of the intestine slides into an adjacent part of the intestine. Adult intussusception is mainly due to benign or malignant neoplasm. Therefore, in most cases of adult intussusception, treatment by surgery would be preferable to conservative therapy. However, we report on a 28-year-old female patient who underwent intussusception operation delayed 3 months. Abdominal computed tomography 3 months ago showed a small bowel intussusception measuring 20 cm long. Three months later, the previously identified small bowel intussusception appeared without change. The patient underwent surgery, and ectopic gastric mucosa was observed in the biopsy. Therefore, Meckel's diverticulum was diagnosed.

Gastrointestinal stromal tumor is a rare tumor which arises from the whole gastrointestinal tracts and most of it is detected in the stomach. It is uncommon with small intestine originated gastrointestinal stromal tumor and more uncommon with lymphatic metastasis. We experienced an unusual case of the small bowel gastrointestinal stromal tumor during experimental autopsy. Two primary tumors with central necrosis were detected in the ileum. The sizes of each tumor were $6.1{\times}3.4{\times}4.0$ cm and $3.7{\times}4.2{\times}3.2$ cm. There was extensive lymphatic metastasis on the greater omentum and mesenteric, iliac lymph nodes were also involved. With histologic findings, the eosinophilic spindle cells were densely distributed. Immunohistochemical findings were CD117 (-), CD34 (+), desmin (-), and S-100 protein (-). Therefore, we diagnosed the tumors as small bowel gastrointestinal stromal tumors with broad lymph node mestasis.

Small bowel metastasis of pleomorphic carcinoma of the lung is very rare. A 58-year-old man was admitted to our hospital with abdominal palpable mass in the right upper quadrant area. He underwent right middle and lower lobectomy for early stage pleomorphic carcinoma of the lung approximately 3 months ago. USG-guided biopsy was performed for abdominal mass. Pathologic examination revealed a metastatic pleomorphic carcinoma from the lung. He received chemotherapy followed by radiation therapy but died due to septic shock caused by intestinal stenosis and adhesion. We report the first case of small bowel metastasis by pleomorphic carcinoma of the lung after curative surgery.

Abnormal gastric emptying time of dog by alien substance, neoplasm, pyloric antrum hyperplasia, stomach surgery, electrolyte imbalance, stomach-dilated torsion is clinically important as a digestive disease. Therefore study aims to provide basic data on the clinical usefulness of gastric emptying time test which uses radiopaque Kolomark developed in Korea rather than using the existing BIPS for the dog. 9 beagles were used for this experiment and their average weight was about 10.3kg with 2.5 year-old average age. For the test, fast for 12 hours was made without chemical sedation, and just before the test, 1 capsule of Kolomark was fed with 25% of daily feed amount, and we took photographs at ventrodorsal and right lateral position after 2, 4, 8 and 12 hours. As for interested reading area, we observed entire stomach from cardia to stomach pyloric part, and as for analysis method, we counted Kolomarks remained in the stomach per time and judged only P value below 0.05 to be meaningful by using Friedman Test. After feeding Kolomark through oral cavity, it took average 7.55 hours for the Kolomark to have escaped from the stomach to small intestine. In this study of gastrointestinal tract passing time after feeding matured dog, we used Kolomark and expect that it could be a basic data for normal gastrokinetic time.
