Extramedullary plasmacytoma is a rare disease that is histopathologically defined as a solitary tumor composed of a monoclonal proliferation of cells with plasmacytic differentiation in an extramedullary site. Most of these tumors occur in the submucosa of the upper aerodigestive tract, and they rarely occur in the small bowel mesentery. We report here on a case of extramedullary plasmacytoma of the small bowel mesentery that was in association with a cecal cancer. Abdominal ultrasound and CT revealed a lobulated soft tissue mass with a cystic portion and peripheral calcification. In this case, the preoperative radiological diagnosis was difficult due to accompanying cecal cancer.

Intussusception of the appendix is an uncommon condition and the diagnosis is rarely made preoperatively. Intussusception of the appendix may mimic a neoplastic lesion. Colonoscopy is a valuable tool for diagnosis of the appendiceal intussusception. A 17-yr-old female admitted with repeated abdominal pain, nausea, vomiting and febrile sensation. We diagnosed as appendiceal intussusception by colonoscopy, which showed a polypoid tumor (about 1.5 cm) in the cecum. This sessile polypoid mass looks like foreskin or glans. We present colonoscopic finding of appendiceal intussusception and review the literature.

Acute appendicitis (AA) is one of the most common causes of acute abdominal pain, which can progress to perforation of the appendix and peritonitis. Recently, AA has been classified into uncomplicated (nonperforated, no phlegmon) or complicated (abscess, perforation, phlegmon) appendicitis, for an appropriate initial treatment. With respect to surgical treatment of AA, laparoscopic surgery has been widely accepted worldwide as a safe and feasible first-line treatment. Over the last decade, non-operative treatment has been proposed as an alternative to surgery in uncomplicated AA, and has also played an important role in the management of complicated AA. AA is also the most common cause for abdominal surgery during pregnancy, though an accurate diagnosis of AA during pregnancy is challenging. In this review, the topics being discussed include: 1) Non-operative management for uncomplicated AA, 2) Management for AA in pregnancy, 3) Management for complicated appendicitis (especially immediate laparoscopic surgery for appendiceal abscess), 4) Appendiceal neoplasms related to complicated AA.

Ulcerative colitis (UC) is an inflammatory disease primarily involving the colonic mucosa. The extension of classic UC is uniform and continuous with no intervening areas of normal mucosa. The rectum is usually involved and the inflammation extends proximally in a continuous fashion for a variable distance. However, as more patients get colonoscoped, it had been reported that there is a wide spectrum to what is called UC. There appear to be a few patients with otherwise typical UC but with rectal sparing. And also there are patients with classic distal UC who have an isolated area of cecal disease and segmental UC with skipped area. We have experienced a case of atypical UC initially presented as a isolated lesion around the appendiceal orifice with the segmental distribution of inflammatory change without an active inflammatory lesion in the rectum. It was considered that understanding of the significance of an isolated lesion in the appendix would contribute to the elucidation of the pathogenesis of UC.

This report includes experiences of 63 cases of lntussusception treated in Severance Hospital from October 1964 to September 1968. 1. In age distribution, 44 cases were observed under one year of age (69.9%) and peak incidence occurs from the 4th to 7th month (38%). Males showed a decidedly higher incidence than females with a ratio of 2.3:1. Seasonal incidence showed 33.3 per cent in the Summer. 2. The cardinal symptoms and signs were irritability or abdominal pain, palpable abdominal mass, vomiting, and bloody mucous stools. 3. 7 out of 63 cases had an underlying cause; Meckel's diverticulum 2, enteric cyst 1, submucosal cyst 1, lymphosarcoma 1, reticulum cell sarcoma 1, and malrotation, and 5 cases out of six were under 3 years of age. 4. Of 63 cases, operative intervention without trial of barium enema reduction was used in 24 cases, 7 cases had only diagnostic barium enema. In the rest of the cases, namely 32 cases, hydrostatic pressure barium enema was performed and successful reduction was accomplished in 13 cases.

Abdominal actinomycosis is a rare and chronic progressive disease, especially in children. Clinically, it has non-specific symptoms and diagnostic findings as well as low prevalence, making it very difficult to diagnose prior to intraoperative pathological confirmation. For this reason, abdominal actinomycosis is commonly misdiagnosed as appendicitis. After the histopathological diagnosis of abdominal actinomycosis is made, patients should be administered an appropriate antibiotic such as penicillin. Here we describe a case of appendiceal actinomycosis in an 18-year-old girl who was initially diagnosed with acute appendicitis.

Laparoscopic resection of appendiceal mucoceles has recently been described, but the safety and efficacy are controversial. We present two cases of laparoscopic mucocelectomies involving 14 and 15 cm cystic masses originating from the appendix. The laparoscopic mucocelectomies were performed using four ports. From the beginning of the procedure, a laparoscopic bag was used to safely contain the mucocele, prevent rupture of the mucocele, and retract the mucocele. An endoscopic stapling device was used to transect the base of the cecum. Minimal handling was achieved by gravity and with the use of laparoscopic instruments. Laparoscopic appendectomies are widely performed for acute appendicitis, but laparoscopic resection is not routinely performed for an appendiceal mucocele because of the risk of perforation and subsequent pseudomyxoma peritonei. We report two cases of laparoscopic appendiceal mucocelectomies, which were performed safely with laparoscopic instruments and minimal manipulation.

Idiopathic cecal ulcer is a rare disease entity of unknown cause diagnosed by ruling out other known causes of cecal ulceration. The most common complication of an idiopathic cecal ulcer is bleeding; perforation, peritonitis, abscess, and stricture formation have been noted. The authors treated a 53-year-old woman who presented with fever and intermittent right upper quadrant abdominal pain. Multiple pyogenic liver abscess and a solitary cecal ulcer were diagnosed by radiologic, endoscopic, and pathologic examination, followed by laparoscopic cecectomy. After extensive study, we concluded that this patient's liver abscesses were a complication of the idiopathic cecal ulcer. Herein, we report a case of multiple pyogenic liver abscess caused by microperforation of idiopathic cecal ulcer.

Behcet's syndrome is a multi-systemic and chronic disorder that affects many organs. It has been suggested that the diagnosis was based on the presence of the 'major' and 'minor' clinical criteria. When thromobophlebitis, arthritis, central nervous system or gastrointestinal lesions are also present. Behcet's syndrome will be thought to be present in the appropriate geographic area. We report a case of superior vena cava syndrome caused by Behcet's disease in a 40-year-old man with recurrent oral aphthous ulcers and skin rashes on the anterior chest wall. There were multiple thrombosis of the superior vena cava, innominate and subclavian veins. This patient also had a solitary cecal ulcer with an ileocecal fistula and downhill varix. The chest CT, veno-cavography, pulmonary angiography and colon study were taken and follow-up was performed.
