The term "mucocele" refers to a grossly dilated appendix by mucus (fig.1). In 2016, a consensus for classification and pathologic reporting of pseudomyxoma peritonei (PMP) and associated appendiceal neoplasia [ 2 ] was reached, and it enabled the uniform use of terminology.

BACKGROUND: Appendiceal mucocele is a rarely seen disease which occurs when the appendix lumen is filled and obstructed by mucous.
However, the origin, pathology, treatment, prognosis, and even the very definition remain controversial [ 2, 3]. However, the safety and outcome of laparoscopic surgery for appendiceal intussusception caused by mucocele of the appendix is unclearly and the report is few (4,5,26). Mucinous lesions of the appendix and ovary are commonly encountered in routine practice. It has an incidence of 0.2-0.3% of all appendectomies, and co-rresponds to 8% of all tumors of the appendix. Mucocele of the appendix can also result from alterations in the cecum, such as fecal impaction, polyps or malignant neoplasms, which, in theory, can obstruct the appendiceal ostium. The preoperative diagnosis is difficult; in most cases, it´s an intraoperative finding.
conclusion: We review the pathology as well as the different pathological conditions that may lead to an appendiceal mucocele.

Appendiceal mucocele refers to dilatation of the appendiceal lumen by an abnormal accumulation of mucus. Appendiceal mucocele is usually discovered incidentally during radiologic or endoscopic evaluation for unrelated complaints. The male to female ratio is 1:4 and the average age at the time of diagnosis is over 50 years.
A mucocele may result from appendiceal obstruction resulting in a retention cyst or, more commonly, may be a feature of a benign or a malignant neoplasm involving the appendix. The latter diagnosis is one which the clinician should be aware of, particularly in patients with longstanding history.

Appendicular mucocele (AM) is the chronic transformation of the appendix into a mucus-filled sac. The appendix containing gelatinous mucus with numerous round bodies was distended to the size of an egg. The clinical presentation of a mucocele is usually non-specific and up to fifty percent are discovered incidentally at surgery .
There is a female predominance (female/male: 7/1) and an avarage age of diagnosis over 50s. Appendiceal Mucoceles Morphological description Cystic dilatation of appendix caused by accumulation of mucus secretion 0.2-0.4% appendicetomy specimens Course and prognosis depends on histological subtype Luca et al. The incidence is 0.29 - 0.4% of all appendectomied specimens.1It may be due to a benign or malignant process. This is the review of research articles on the topic of appendiceal mucocele at PubMed, searched by using the term “appendiceal mucocele” and “mucocele”. However, appendiceal myxoglobulosis associated with perforated barium appendicitis has not been previously reported. Ultrasonography or computed tomography is beneficial, but preoperative detection is rare. Mucocele of appendix is an obstructive dilatation of the appendiceal lumen by accumulation of mucus. The aim of this study is to report a case of a mucinous appendiceal neoplasm presented as acute appendicitis, discussing the clinical and surgical approach in the emergency setting.
Appendiceal mucocele is a term referring to the abnormal accumulation of mucus into the lumen of appendix regardless of the underlying cause. appendiceal origin: A clinicopathologic analysis of 101 patients uniformly treated at a single institution, with literature review. Mucocele: A retention cyst of the salivary gland, lacrimal sac, paranasal sinuses, appendix, or gallbladder.(Stedman, 26th ed) Appendectomy: Surgical removal of the vermiform appendix. The neoplastic mucocele and retention cysts are clinically and radiologically difficult to differentiate, but malignant mucoceles have additional findings ,,. mucocele of the appendix is a cystic mass with a thin wall and of low density, which communicates directly with the cecum (Figure 1). Minimally invasive appendectomy for resection of appendiceal mucocele: Case series and review of the literature. They are a rare form of an appendiceal mass and develop from both benign and malignant processes. tadenocarcinoma arising from the appendiceal stump: preoperative diagnosis based on the onion skin sign.
Nevertheless, if we can handle the tissue with minimal manipulation, and can secure enough safety by using various laparoscopic instruments, laparoscopic re-section of an appendiceal mucocele might be an alter-native surgical option to open surgery. More than two-thirds of patients have their appendiceal mucocele removed on incidental finding [ 3 ] . Moreover, the mechanism of obstruction is different from those described in literature (compression of ileocecal junction by mucocele or intussusceptions of the tumor). As a result, most appendiceal epithelial tumors are mucinous and start as mucoceles.11 It falls under the category of rare diseases. Mucocele on histopathological basis classified as (1) simple accumulation of mucus within the lumen of appendix due to . The pathology report revealed that both the appendix and the thickened part of the cecal wall at ileocolic junction were non-neoplastic mucocele.
The clinical findings and CT images are [investigate]d in order to fulfill an early preoperative diagnosis and increase awareness of low-grade appendiceal mucinous neoplasm (LAMN) confined to the appendix. An intra-operative frozen sectioning is important to de-termine the hystologic type and the type of surgery re-quired.

Introduction: Appendicular mucocele is a rare disease and constitutes 0.2-0.3% of surgically excised appendicitis, more frequently in females (3: 1) and with an average age of 55 (2.4 , 6.12). In our study, we aimed to reveal the surgical approach of our clinic, features of tumors, and clinical presentations in line with literature in cases of appendix mucocele. The mucus material contains epithelial adenoma cells with a low or high grade of dysplasia. Mucocele of the appendix was first described by Rokitansky.10 This disease is characterized by dilatation of a lumen as a result of an accumulation of a large amount of mucus.
Appendiceal mucoceles are rare cystic lesions with an incidence of 0.3-0.7% of all appendectomies. Saliva is hugely important, as it acts as a kind of natural mouthwash, helping to keep the tongue, gums teeth and soft tissue lubricated and rinsing away harmful substances such as particles of food and bacteria. The presence of wall calcification strongly supports a diagnosis of appendiceal mucocele , but this characteristic is seen in less than 50% of cases [5, 6]. The tumor was diagnosed as mucocele of the appendix after admission and surgically removed. The lesion was surgically removed and final pathologic examination revealed malignancy. It is a descriptive term denoting an obstructive dilatation of the appendicular lumen by mucinous secretions. INTRODUCTION Acute appendiceal diverticulitis (AAD) is a rare cause of acute abdomen, with an incidence of 0.004 % to 2.1 % in patients undergoing surgery for acute appendicitis, which is why it has been considered a variant of the latter (1,2). Neoplasia of the appendix, although rare, is an important diagnosis to consider in patients with a mucocele of the appendix.
