PURPOSE: This study was undertaken to describe the clinicopathologic characteristics and evaluate the appropriate management of appendiceal tumors. METHODS: During 5 years between Sep. 2000 and Sep. 2005, 28 appendiceal tumors were identified in a retrospective review of 3,744 cases of appendectomy or right hemicolectomy pathology. RESULTS: Carcinoids were found incidentally as appendicitis. Mucinous cystadenomas were common in women older than 50 aged; half of the cases presented with appendicitis and the other half presented with non-specific abdominal symptoms such as palpable mass, intestinal obstruction and intussusception. Carcinomas were common in the older patients (mean age: 62.8 years) and this presented as periappendiceal abscess. Right hemicolectomy was undertaken when there was evidence of tumor spread beyond the resection margin, and carcinoma and tumors were located in the appendiceal base. Recurrence and metastasis were identified only in the carcinoma cases. CONCLUSION: Most appendiceal tumors presented with appendicitis and periappendiceal abscess. One stage curative resection was possible in more than 76% of the patients, and the prepoperative diagnosis rate was less than 35%. The preoperative diagnosis did not have much impact on the clinical course, and the postoperative pathology was important in determining the additional treatment. Close follow-up is needed for the early detection of recurrence, and all the carcinomas that were advanced as serosal involvement, peritoneal seeding and liver metastasis.

Adventitial cystic disease (ACD) is an uncommon vascular disease of an unknown origin, and this malady can be suspected in a young, healthy patient who has sudden onset of claudication. We describe here a case of ACD of the right popliteal artery. A 43-year-old male presented with 4 month history of severe right leg claudication. He had no other atherosclerotic predisposing history except for 10 pack years of smoking. On examination, the right femoral pulses were normal, the popliteal artery absent and the dorsalis pedis and posterior tibial artey pulses were decreased. The ankle-brachial pressure index (ABI) was 0.4. Ultrasonography showed a hypoechoic cystic lesion with a well-defined marin along the arterial wall. Computed tomography showed a round hypodense cystic mass with thin enhancing rim and a non-enhancing center in the popliteal fossa. Operatively, the 2.5 cm-sized expanding cyst indented the popliteal artery, which involved half of its diameter with adhesion to the adhesion to the adjacent structures. The artery had no thrombosis and it was a short-segment lesion with luminal patency, but half of the arterial wall was thickened with inflammation. Partial excision of the cyst wall and evacuation of the gelatineous materials was performed. Postoperatively, his symptoms improved somewhat, but ABI was 0.6. On the angiography, there was residual stenosis and contrast pooling. These findings disappeared after balloon angioplasty. he was asymptomatic 6 months later with an ABI >1 in the right side.

Appendiceal mucocele is a cystic dilatation of the appendiceal lumen with mucus, which may be caused by either benign or malignant diseases. In this report, five cases of appendiceal mucocele are reported, three of which had a preoperative diagnosis of mucocele, whereas the others were found incidentally during the operation under the diagnosis of intussusception and periappendiceal abscess. All five patients underwent surgical resections, including one ileocecal resection and four right hemicolectomies. Histopathology revealed a mucinous cystadenoma in four cases, and a mucinous cystadenocarcinoma in one. There was no disease-related death during 18 months of follow-up.
