Endometriosis of the appendix can be an incidental finding or a cause of appendicitis, intussusception, perforation or retention mucocele. Intestinal metaplasia of appendiceal endometriosis may occur, which can lead to a misdiagnosis of low-grade appendiceal mucinous neoplasm. On a retrospective search of the pathology database from 2001 to 2015, we identified 78 appendiceal endometriosis cases and intestinal metaplasia was present in 10/78 (13%) cases. In most of the cases (90%), the foci of intestinal metaplasia were mainly localized close to the mucosa...

Anomalies of the appendix are extremely rare, and a horseshoe appendix is even rarer. A literature search has revealed only five reported cases. In this report, we present a case of a horseshoe appendix.A 78-year-old man was referred for further examination following a positive fecal occult blood test. A mass in his ascending colon was detected on colonoscopy, while computed tomography showed that it was connected to the appendix. Tumor invasion derived from the ascending colon or appendix was suspected. We diagnosed ascending colon cancer prior to laparoscopic ileocecal resection...

Adenocarcinoma arising in an ileal diverticulum are very rare. A 66-year-old man was recognized to have high serum CEA level and periappendiceal polycystic tumor in CT findings. Colonoscopy showed no abnormality in the ileocecal mucosa. However, the patient was suspected of appendiceal adenocarcinoma by PET/CT, which revealed FDG uptake with SUVmax of 3.9 in the tumor, and underwent radial surgery by single-incision laparoscopic surgery. Intraoperative findings showed the mass in the mesenterium of the terminal ileum but not the abnormality of the appendix...

A 68-year-old man presented with progressive right lower quadrant abdominal pain and tenderness without rebound tenderness, and with constipation during the prior 9 mo. Abdomino-pelvic computed tomography and magnetic resonance imaging demonstrated a dilated appendix forming a fistula to the sigmoid colon. Open laparotomy revealed a bulky abdominal tumor involving appendix, cecum, and sigmoid, and extending up to adjacent viscera, without ascites or peritoneal implants. The abdominal mass was removed en bloc, including resection of sigmoid colon, cecum (with preservation of ileocecal valve), appendix, right vas deferens, testicular vessels, and minimal amounts of anterior abdominal wall; and shaving off of small parts of the walls of the urinary bladder and small bowel...

OBJECTIVES: Currently the management of appendicular mass remains controversial. Many authors advocate conservative management followed by delayed appendectomy, whereas others favour inmediate appendectomy. The aim of our study is to compare both treatments. METHODS: A descriptive and observational study over 46 patients treated for appendiceal mass at our center in the last ten years was performed. Patients were categorized as group 1, early surgical intervention (54...

BACKGROUND: Pain associated with appendiceal endometriosis can mimic other intra-abdominal pathology. The diagnosis is usually obvious during gross inspection of the appendix; however, the absence of classical macroscopic appearances may lead to missed cases in which the patient's pain is misdiagnosed and inappropriately managed. CASE: A 34-year-old woman presented with cyclical right iliac fossa pain and an elevated serum C-reactive protein of 13 mg/L (normal < 5 mg/L)...

Low-grade appendiceal mucinous neoplasm is a neoplasm typically of appendiceal origin, which is characterized by diffuse peritoneal involvement by pools of mucin with mucinous epithelium lacking high-grade cytologic atypia, and clinically presents as suspected peritoneal carcinomatosis. A similar clinical presentation can sometimes be seen with disseminated low-grade serous carcinomas of the peritoneum, fallopian tubes, or ovaries; however, this neoplasm is histologically characterized by tubal-type epithelium and invasive or confluent growth...

Appendiceal adenocarcinoma typically presents as an incidentally noted appendiceal mass, or with symptoms of right lower quadrant pain that can mimic appendicitis, but local involvement of adjacent organs is uncommon, particularly as the presenting sign. We report on a case of a primary appendiceal cancer initially diagnosed as a rectal polyp based on its appearance in the rectal lumen. The management of the patient was in keeping with standard practice for a rectal polyp, and the diagnosis of appendiceal adenocarcinoma was made intraoperatively...

Inflammatory myofibroblastic tumor (IMT) is a rare soft-tissue neoplasm of unknown etiology. It mimics, clinically and radiologically, malignant tumors. Histologically, this tumor is composed of differentiated myofibroblastic spindle cells accompanied by an inflammatory infiltrate, with numerous plasma cells and/or lymphocytes. Initially described in the lung, numerous extrapulmonary sites of this tumor have been found but appendiceal IMT is rare, especially in adult women. In this study we aimed to examine the literature as well as to describe a case of a 42-year old woman that we operated on that presented as an appendiceal mass that obstructed the lumen of the appendix and caused acute appendicitis...

INTRODUCTION: Appendiceal mucocele is a relatively rare condition characterized by progressive dilation of the appendix caused by intraluminal accumulation of mucoid substance. Its incidence is 0.07 - 0,63% of all appendectomies performed. CASE REPORT: We report the case of a 70-year-old man who came to our observation with gravative pain in right lower abdominal region. A computed tomography abdominal scan revealed a cystic/tubular structure like an appendicular mass with wall enhancement but without calcifications suggestive of a mucocele...

Pseudomyxoma retroperitonei is a rare condition, characterized by accumulation of mucinous material in the retroperitoneal space, originating predominantly from the appendiceal mucinous neoplasms. A72-year-old male patient presented with a history of progressive right side abdominal pain for 5 months with a palpable abdominal mass. Ultrasound, computerized tomography, and magnetic resonance imaging showed large right abdominal multiloculated cystic lesion with heterogeneous echoic contents. Colonoscopy revealed normal mucosa with extramural pressure on the right colon and cecum...

The fifth leading cause of cancer-related deaths among women in the United States is ovarian cancer. An estimated 21,980 new cases and 14,270 estimated deaths occurred nationwide in 2014. More than two-thirds of cases of ovarian cancer are diagnosed at stage III or IV when the peritoneal cavity or other organs are affected. Primary appendiceal malignant neoplasms may mimic advanced-stage ovarian cancer and can be misdiagnosed because of its presentation as a palpable adnexal mass. The authors describe a 42-year-old woman who was admitted to the department of obstetrics and gynecology to receive treatment for presumed advanced-stage ovarian cancer...

Mucinous cystadenoma of the appendix is a rare condition that develops as a result of proliferation of mucin-secreting cells in an occluded appendix. Mucinous cystadenoma of the appendix presenting as an umbilical hernia is a rare clinical entity. The most common causes of this condition are known to be ascites, hepatitis and cirrhosis; however, the patient in the present study, was diagnosed as hepatitis- and cirrhosis-negative, with no history of chronic coughing or constipation. The aim of the present study was to report a rare case of mucinous cystadenoma of the appendix presenting as an umbilical hernia in a 66-year-old female patient...

Introduction Malrotation of the midgut and appendiceal mucocoele are both extremely rare pathological conditions in adults. To our knowledge, there are only two reported cases in the English literature with a combination of both conditions. Case History A 65-year-old man presented with a 10-day history of upper abdominal pain associated with abdominal bloating and weight loss. He was otherwise fit and healthy with no significant past medical history. On examination, his abdomen was soft with tenderness and palpable fullness over the left upper quadrant...

A 65-year-old woman presented to a nearby clinic with a painful mass in the right lower abdominal region. She was suspected of having an appendiceal tumor on abdominal computed tomography (CT) and was referred to our hospital for surgery. Blood testing revealed increased inflammatory markers. Contrast-enhanced abdominal CT revealed a mass with poorly defined margins in the ileocecal region, which was adjacent to the external iliac vessels. A barium enema revealed unilateral wall deformities in the cecum through to the terminal ileum, whereas lower gastrointestinal endoscopy showed no clear epithelial tumor component...
