Tumors of the appendix are extremely rare and constitute about 0.4% of all tumors of the gastrointestinal tract. The most common benign neoplasm is mucinous cystadenoma, which can be found in 0.6% of all excised appendices and it rarely produces any symptoms. We present the case of a female patient who underwent surgery in the Department of Surgery due to suspicion of an appendicular abscess. On the postoperative pathology study, the diagnosis of a tumor of the appendix (mucinous cystadenoma) was made. Mucinous cystadenoma is rarely included in the differential diagnosis of a non-specific abdominal pain accompanied by non-characteristic laboratory test results and imaging studies...

BACKGROUND: The term mucocele refers to the dilatation of the appendix due to mucus, and it is an uncommon disorder with an estimated incidence of 0.2%-0.3% of all appendectomies performed and 8%-10% of all appendiceal tumors. It is often asymptomatic, but may manifest appendicitis-like symptoms. METHODS: Twenty-six patients (14 females and 12 males) were operated on due to mucocele of the appendix. Sixteen patients exhibiting the characteristics of clinically acute appendicitis required an emergency operation...

BACKGROUND Low-grade appendiceal mucinous neoplasms (LAMNs) are cytologically low-grade tumors of the appendix and are a frequent cause of pseudomyxoma peritonei. They can become a diagnostic challenge when they metastasize to the ovaries, where they may mimic primary ovarian mucinous tumors. CASE REPORT We report the case of a patient with very large bilateral ovarian mucinous tumors and a concurrent minute LAMN incidentally discovered in a grossly normal appendix. A primary ovarian tumor was suspected, but histological analysis of the ovaries suggested an appendiceal origin...

BACKGROUND: Mucinous appendiceal adenocarcinomas (AAs) are the most common histological subset of AAs. Nonmucinous AAs have been infrequently studied. We performed a single-center retrospective study to investigate this histological subtype. METHODS: We reviewed 172 patient records with nonmucinous AAs treated at MD Anderson Cancer Center from Jan, 1990 to Jun, 2015 and recorded patient demographics, tumor characteristics, treatment, and outcomes. Response rate (RR) was assessed semi-quantitatively (response/no response) according to the treating physician's findings...

Sung-Sik Han, Paul H Sugarbaker
A potential site for incomplete cytoreduction in patients with peritoneal metastases is the foramen of Winslow, especially the posterior aspect of the hepatoduodenal ligament. The Kocher maneuver can be used to rotate the duodenum, head of pancreas, and portal structures 180°. In so doing, the foramen of Winslow is clearly exposed for peritonectomy. Residual tumor at this site is a prominent cause of unnecessary treatment failure in the management of patients with mucinous appendiceal neoplasms.

BACKGROUND: Low-grade appendiceal mucinous neoplasms are rare. Both classification and management vary. This study aimed to follow up on patients with a diagnosis of LAMN after primary surgery with computer tomography (CT) scans to examine the risk for the development of pseudomyxoma peritonei (PMP). METHODS: This population-based prospective study investigated patients who underwent appendectomy between 2007 and 2013 and had histology results demonstrating the presence of LAMN...

Acute appendicitis with its characteristic clinical course is one of the most common diagnoses that require urgent surgery. The following three case reports present patients with symptoms typical of acute appendicitis which was, however, not confirmed intraoperatively. Preoperative CT or MRI were not requested because symptoms clearly indicated acute appendicitis. The first case describes a male patient with right-sided diverticulitis, the second case report involves a pregnant woman in 33rd week of gestation with right adnexal torsion due to a dermoid cyst, and in the last report, a case of spontaneous perforation of appendiceal mucinous neoplasm is presented...

Objectives: Determination of the primary site of origin for mucinous neoplasms identified in the peritoneal and/or pelvic cavities may be challenging, with major differential diagnoses including appendiceal mucinous neoplasm (AMN) and ovarian mucinous neoplasm (OMN). Special AT-rich sequence binding protein 2 (SATB2) has been shown to be highly selectively expressed in the lower gastrointestinal tract, including the appendix. Methods: We investigated the utility of a dual stain (DS) with SATB2 or caudal type homeobox 2 (CDX2) and cytokeratin 20 (CK20) or villin in distinguishing AMNs from OMNs...

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 an appendiceal mucocele, for which she received a full oncological procedure. The histology report showed a low-grade appendiceal mucinous neoplasm, and the patient underwent six cycles of chemotherapy...

BACKGROUND: Appendiceal cancers are rare and consist of carcinoid, mucocele, pseudomyxoma peritonei (PMP), goblet cell carcinoma, lymphoma, and adenocarcinoma histologies. Current treatment involves surgical resection or debulking, but no standard exists for adjuvant chemotherapy or treatment for metastatic disease. METHODS: Samples were identified from approximately 60,000 global tumors analyzed at a referral molecular profiling CLIA-certified laboratory. A total of 588 samples with appendix primary tumor sites were identified (male/female ratio of 2:3; mean age =55)...

INTRODUCTION: Appendiceal diverticulitis is a rare pathology that mimics acute appendicitis. Appendiceal diverticula are classified into congenital and acquired with difference in incidence and pathogenesis. Appendiceal diverticulitis is often overlooked because of mildness of symptomatology with increasing risk of complications, such as perforation. Appendiceal diverticula are often associated to higher risk of neoplasm especially carcinoid tumors and mucinous adenomas. PRESENTATION OF CASE: A 40-year-old caucasic male presented into Emergency Room with right lower quadrant pain associated with vomit, abdominal tenderness, fever and moderate leukocytosis (11...

BACKGROUND: It has been increasingly recognized that appendiceal mucinous neoplasm with peritoneal dissemination is not a homogenous disease. OBJECTIVE: This study aimed to examine the impact of different histological subtypes on survival of a large cohort of patients with appendiceal mucinous neoplasms uniformly treated by cytoreductive surgery and intraperitoneal chemotherapy. DESIGN: This was a retrospective study of prospectively collected data of patients with peritoneal dissemination of appendiceal neoplasm who underwent cytoreductive surgery and intraperitoneal chemotherapy...

Low-grade appendiceal mucinous neoplasms (LAMNs) are neoplastic lesions with potential progression to pseudomyxoma peritonei (PMP). In most cases, diagnosis is made because of suspected acute appendicitis or incidentally by computed tomography (CT). However, incidental diagnosis during colonoscopy is rare. We present the case of a 63-year-old man with a LAMN type 1 lesion, diagnosed at routine colonoscopy for surveillance of ulcerative colitis. Because in earlier surveillance colonoscopies, this lesion was misinterpreted as fecal polution, for the first time, this case describes retrospectively a 3-year endoscopic follow-up of LAMN type 1, underlining the benign course of these kind of lesions compared to type 2 lesions with submucosal infiltration...

BACKGROUND: Appendiceal mucinous cystadenoma can present in various ways, and it is most commonly encountered incidentally during appendectomy, but mechanical intestinal obstruction secondary to an appendiceal mucocele has been rarely reported. METHODS: We report a case of mechanical intestinal obstruction secondary to appendiceal mucinous cystadenoma. After nasogastric decompression and initial aggressive intravenous fluid resuscitation, an emergency operation was performed under the diagnosis of acute mechanical intestinal obstruction...

Primary mucinous adenocarcinoma of the appendix is a rare gastrointestinal malignancy. Fistulous tract formation is a complication that is cited in literature. An 85-year-old man with multiple comorbidities presented with several weeks of persistent non-bloody diarrhea. Laboratory work-up was non-diagnostic. Abdominal imaging with barium contrast showed an enterocolonic fistulous tract extending from the duodenum to the cecum involving an enlarged appendiceal mass. Subsequent biopsy confirmed mucinous appendiceal neoplasm with peritoneal spread to the liver and mesentery...

A 73 year-old woman who was treated for breast cancer and visited our hospital regularly was suspected of having a mucinous cystadenoma of the appendix. Malignancy could not be determined using abdominal computed tomography, magnetic resonance imaging, or colonoscopy. Even if mucinous cystadenoma is benign, there is the possibility that the tumor will rupture, discharge its contents, and cause pseudomyxoma peritonei. We performed laparoscopic appendectomy. According to the histopathological results, the tumor was diagnosed as a low grade appendiceal mucinous neoplasm...

We encountered a case of giant appendiceal mucinous neoplasm that was treated with laparoscopic surgery. The patient was a 77-year-old man with constipation. Lower endoscopy demonstrated a giant SMT-like tumor in the cecum, and abdominal computed tomography revealed a giant appendiceal mucinous neoplasm and nearby lymph nodes swelling. Hematological examination showed an elevated serum CEA level. We performed laparoscopic ileocecal resection for a definite diagnosis and treatment. The postoperative course was uneventful...

Low-grade appendiceal mucinous neoplasm(LAMN)is a rare disease. In consideration of consistency with the 2010WHO Classification, LAMNwas classified in the Japanese Classification of Colorectal Carcinoma 8th edition. The present study involved 14 patients with LAMNover a 5-year period. The preoperative diagnosis was made as mucocele of the appendix in 9 cases. Operative interventions included ileocecal resection in 6 cases(laparoscopic; 3 cases)and appendectomy in 8 cases (laparoscopic; 6 cases). Histopathologically, there was no LNpositive case...

OBJECTIVE: The aim of this study was to assess the importance of appendectomy during surgery for mucinous ovarian cancer. It can be difficult to distinguish between primary ovarian and primary appendiceal cancers clinically, histologically, and immunohistochemically. Removal of the appendix may facilitate differential diagnosis, improve staging, and possibly increase 5-year survival but may also be associated with increased postsurgical morbidity. In the largest population published to date, we analyze and discuss these matters...
