Appendiceal tumours are uncommon but may be present in 0.9-1.4% of all appendicectomy specimens. While carcinoid tumours and adenocarcinomas comprise the majority of appendiceal tumours, rarely, lymphomas or sarcomas may also present in the appendix. Appendiceal leiomyosarcomas are rare, and to date, only a handful of cases have been reported. The current paper presents a case of giant appendic...

CONTEXT The rates of appendiceal rupture and negative appendectomy in children remain high despite efforts to reduce them. Both outcomes are used as measures of hospital quality. Little is known about the factors that influence these rates. OBJECTIVE To investigate the association between hospital- and patient-level characteristics and the rates of appendiceal rupture and negative appendectom...

Appendiceal anomalies are extremely rare malformations. We presented the case of a patient 43-year-old who had undergone emergency surgery for bowel occlusion. Incidentally we have found an "horseshoe-shaped" appendix which removed. After review of the literature we have introduced this appendiceal variant in a complete classification of appendiceal anomalies.

INTRODUCTION Acute appendiceal diverticulitis is an unusual cause of acute abdomen, considered clinically indistinguishable from acute appendicitis. MATERIAL AND METHODS In a historic cohort study with 27 cases of appendiceal diverticulitis and 54 cases of acute appendicitis, we compared clinical characteristics, diagnostic tests and pathology findings of the two processes. RESULTS Mean age...

Appendiceal tumors are rare, late diagnosed neoplasms that may not be differentiated from adnexal masses even by advanced imaging methods and other diagnostic procedures. They may be asymptomatic and remain undiagnosed until surgery. We report a case of an 80-year-old postmenopausal woman presenting with a pelvic mass and a history of weight loss. The patient underwent laparotomy which revealed...

Carcinomas of the appendix are exceedingly rare tumors and have an annual age-adjusted incidence of around 0.4 cases per 100,000. Appendiceal adenocarcinoma accounts for < 0.5% of all gastrointestinal neoplasms and, of these, mucinous adenocarcinomas account for the majority. Published accounts of familial instances of primary appendiceal tumors are strikingly rare. We report two siblings who b...

Appendiceal intussusception is an uncommon form of intussusception. Most of the literature regarding appendiceal intussusception discusses the colonoscopic diagnosis or surgical treatment of the condition. Sonographic findings have rarely been described. We present a case of preoperative sonographic diagnosis of appendiceal intussusception.

INTRODUCTION Acute appendicitis is significantly common. Despite the increased use of computed tomography, the number of perforated cases has been stable in the past three decades. Between 2% and 6% of patients with acute appendicitis present appendiceal mass, often described as inflammatory phlegmon or abscess. Malignant tumors are confirmed by pathological analysis in 0.9-1.4% of all appendec...

PURPOSE Traditional Kasai portoenterostomy and porto-appendiceal duodenostomy have been utilized for biliary atresia. Differences in outcome between patients who underwent either Kasai portoenterostomy or porto-appendiceal duodenostomy were compared. METHODS A review of all children who underwent a drainage procedure for biliary atresia from 1986 to 2000 (n = 30) was performed. Age at drainag...

We report a case of appendiceal mucinous cystadenoma that was successfully diagnosed preoperatively and treated by laparoscopic resection. We could find volcano sign on colonoscopy and cystic lesion without any nodules at the appendix on computed tomography (CT). Without any malignant factors in preoperative examinations, we performed laparoscopic appendectomy including the cecal wall. We could...
