Intussusception of the appendix is an extremely rare condition. Although approximately 200 cases of appendiceal intussusception have been reported in the literature, very few have ever been diagnosed preoperatively. We report a case of appendiceal intussusception secondary to endometriosis in an otherwise healthy female. The case was diagnosed preoperatively by colonoscopy and treated surgicall...

Background: Appendiceal cancer as a cause of appendicitis is a rare event occurring in approximately 1.0% of all cases of appendicitis. Nevertheless, treatment of appendiceal cancer as appendicitis may have an adverse outcome for the patient, even iatrogenically converting a contained malignant process into a disseminated disease that will have a lethal outcome. Methods: Staging of appendiceal ...

Appendiceal Mucocele is a condition where luminal distention occurs due to mucin accumulation within the appendiceal lumen. This usually results from either benign epithelial proliferation such as; hyperplasia and Lowe-Grade Mucinous Neoplasm or malignant as: cystadenocarcinoma

OBJECTIVE To evaluate the risk factors for appendiceal involvement in women with epithelial ovarian cancer (EOC) who underwent appendectomy at the time of initial surgery. MATERIAL AND METHODS Patients with a final diagnosis of EOC who underwent appendectomy at the time of initial surgery were evaluated retrospectively. Risk factors related to the presence of appendiceal involvement were anal...

Appendiceal cystadenoma, the most common type of what has been generally termed 'mucocele' of the appendix, has unique clinical characteristics. In this study, three similar clinical manifestations of appendiceal cystadenoma are presented, with different subsequent management and diverse prognostic outcomes relating to the characteristics of the disease, the wishes of the patients, the medical ...

BACKGROUND Fine needle aspiration (FNA) of the appendiceal mucocele is generally avoided because of fear that puncture of a distended viscus will lead to rupture or seeding of neoplastic cells and result in localized or diffuse pseudomyxoma peritonei. Cytologic reports regarding FNA of appendiceal mucoceles are virtually nonexistent. CASE A 55-year-old male with a preoperative diagnosis of an...

Primary appendiceal mucinous lesions are uncommon and represent a spectrum from nonneoplastic mucous retention cysts to invasive adenocarcinoma. Low-grade appendiceal mucinous neoplasms (LAMNs) represent an intermediate category on this spectrum and can be classified according to whether or not they are confined to the appendix. Although LAMNs are frequently confined to the appendix, they can a...

Xanthogranulomatous inflammation (XGI) is a rare benign inflammatory disease characterized by aggregation of lipid-laden foamy macrophages. This disease entity has been described in various organs but most commonly in the kidney and gallbladder. The occurrence of this disease in the lower gastrointestinal tract is extremely rare. Its clinical importance is that it can be misdiagnosed as an infi...

The rectum and appendix are the two major sites of well-differentiated endocrine neoplasms (carcinoid tumors) in the lower gastrointestinal tract. Previously, we reported the consistent expression of peripherin in rectal well-differentiated endocrine neoplasms without metastases. However, its expression has not as yet been examined in appendiceal well-differentiated endocrine neoplasms. The aim...
