Appendiceal mass

Amanda Yang Shen, Aaron Stanes
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...

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...

Autoamputation of the appendix has previously been reported in the literature, but it is likely an unusual event. We report a two-year-old male who had previously undergone laparotomy and bowel resection for necrotizing enterocolits. Two years later a calcified intra-abdominal mass was identified on abdominal radiography and ultrasonography. Eventual laparotomy revealed a densely calcified mass within the transverse mesocolon. The mass was uneventfully resected. Pathologic evaluation showed appendiceal tissue, consistent with prior autoamputation of the vermiform appendix...

BACKGROUND: Mucinous cystadenocarcinoma is the second most common etiology of appendiceal mucocele. We report a relatively rare case of a giant appendiceal mucocele caused by mucinous cystadenocarcinoma, which occupied the entire abdomen of an adult woman. CASE PRESENTATION: A 63-year-old woman presented with a chief complaint of abdominal distention. Imaging studies showed a giant cystic mass occupying her entire abdomen. Laparotomy confirmed a giant appendiceal mucocele, and the patient underwent ileocecal resection...

Advanced radiological imaging has largely replaced exploratory operations and has become an essential diagnostic tool clinicians routinely rely on. However, physicians are faced with a lot of radiological findings without histological proof, and assuming a more serious diagnosis may lead to unnecessary investigations and emotional stress for patients. We report an unusual presentation of chronic appendicitis with a synchronous peritoneal nodule on CT in a 76-year-old woman who presented with poor appetite, weight loss and a mass in the right iliac fossa...

Most epithelial neoplasms of the vermiform appendix are of mucinous type and can be stratified into 3 main diagnostic categories: (1) adenoma, (2) mucinous neoplasms of uncertain malignant potential or low-grade mucinous neoplasm, and (3) adenocarcinoma. Clinically, appendiceal mucinous adenomas and adenocarcinomas may present as right lower abdominal pain mimicking acute appendicitis, a mass, or pseudomyxoma peritonei. Nomenclature currently in use to describe and diagnose mucinous tumors of the appendix, particularly those of low morphologic grade, varies among surgical pathologists and centers, resulting in different histologic and clinical features being attributed to these entities in the literature...
