Angélica Morales-Miranda, Ismael Domínguez Rosado, Carlos Chan Núñez, Fredy Chable Montero
Approximately 15% of colorectal cancer (CRC) cases exhibit microsatellite instability (MSI), which appears to be associated with unique biological behavior. The present study presents a case of appendiceal carcinoma associated with MSI that responded well to adjuvant chemotherapy. Clinical, pathological and immunohistochemical (IHC) characteristics have been described. The 60-year-old male patient had suffered from recurrent lower abdominal pain associated with abdominal distention for 6 months; then, following an acute attack, he was subjected to laparoscopic appendectomy...

INTRODUCTION: Acute appendicitis, one of the commonest surgical diagnoses, is rare and more complex presentation in the elderly. Physicians must consider atypical causes appendicitis in this population, which could affect the management of the patient. PRESENTATION OF CASE: An elderly female presented with a two-day history of lower abdominal pain, associated with low-grade fevers and chills. Studies showed leukocytosis and computed tomography (CT) findings consistent with appendicitis...

RATIONALE: Metastasis of cancer cells involves shedding from the primary tumor through various means to distant tissues and organs with continued growth and formation of new metastatic tumors of the same cancer type as the original tumor. The common sites for colon cancer metastases include the pelvis, retroperitoneal lymph nodes, liver, and lungs; Colon cancer metastases to the appendix are rare, as reported in this case. PATIENT CONCERNS AND DIAGNOSES: A 45-year-old man was admitted to our department with a 24-hour history of abdominal distension and incomplete obstruction...

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...

A 73-year-old man underwent a screening colonoscopy, and a depressed lesion in the sigmoid colon was detected. Biopsy revealed a Group V lesion, and he was diagnosed with sigmoid colon cancer. During surgery, there was dense adhesion of the appendix to the sigmoid colon, and sigmoidectomy combined with appendectomy was performed. However, pathological examination revealed goblet cell carcinoid of the appendix with direct invasion into the sigmoid colon. To the best of our knowledge, no similar cases have been reported in Japan...

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...

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...

Three elderly patients presented with acute abdominal pain in the right lower quadrant and leukocytosis. CT-imaging of the abdomen supported the suspicion of acute appendicitis. The patients underwent appendectomy. After pathological examination, two patients were found to have a colon carcinoma. The third patient had a normal appendix; however, adenocarcinoma of the cecum was found four weeks later. The patients underwent a second operation, a right hemicolectomy, within two months. In patients older than 65 years with symptoms of acute appendicitis, colon cancer should be considered in the differential diagnosis...

A 67-year-old lady was found to have a giant appendicolith during a colorectal cancer screening colonoscopy, following a positive faecal occult blood test. Computed tomography confirmed the presence of a calcified giant appendicolith within the base of the appendix, which otherwise appeared normal. Appendicoliths are widely believed to be a major cause of acute appendicitis via obstruction of the appendix lumen, although this is disputed due to a lack of strong evidence. They may also cause chronic abdominal pain...

Primary appendiceal adenocarcinomas are extremely rare entities. Preoperative diagnosis is very difficult and is mainly based on computed tomography (CT) scan findings. Furthermore, in many cases, difficulties in establishing an accurate intraoperative diagnosis have resulted in a two-stage surgical intervention. We herein report a case of a primary appendiceal mucinous adenocarcinoma in a 67-year-old Caucasian man who presented with atypical symptoms of persistent coughing and weight loss. The chest CT showed lesions with features favorable of malignancy...

BACKGROUND AND STUDY AIMS: Dye spray chromoendoscopy and water exchange method both increase adenoma detection rate (ADR). This study was performed to determine if combining indigo carmine with water exchange method will further enhance adenoma detection. METHOD: An IRB-approved randomized, controlled trial was performed in outpatients undergoing screening colonoscopy. The water exchange or combined method with 0.008% indigo carmine added was performed by two endoscopists...

PURPOSE: Chromoendoscopy with dye spray and the water method both increase adenoma detection. HYPOTHESIS: Adding indigocarmine to the water method will enhance further the effectiveness of the latter in adenoma detection. METHODS: Screening colonoscopy was performed with the water method (control) or with 0.008% indigocarmine added (study) by two endoscopists. Randomization was based on computer-generated codes contained in blocks of pre-arranged opaque sealed envelopes...

Appendiceal mucoceles are rare cystic lesions with an incidence of 0.3-0.7% of all appendectomies. They are divided into four subgroups according to their histology. Even though the symptoms may vary - depending on the level of complication - from right lower quadrant pain, signs of intussusception, gastrointestinal bleeding to an acute abdomen with sepsis, most mucoceles are asymptomatic and found incidentally. We present the case of a 70-year-old patient with an incidentally found appendiceal mucocele. He was seen at the hospital for backache...

Complete colonoscopy for cancer screening requires cecal intubation. Failure to reach and examine the cecum may result in missed right colon pathology. We developed and validated a novel classification scheme for the endoscopic appearance of the normal appendiceal orifice (AO). We analyzed 1,456 AO images and grouped them into four categories based on distinguishing features: "diverticuloid," "umbilicoid," "crescent," and "linear." An expert panel classified the images and modified these categories, combining crescent and linear categories into "curvilinear...

A 33-year-old female patient with ulcerative colitis was referred to our outpatient clinic in January 2008 with right lower abdominal pain without bloody diarrhea. Colonoscopy found mild proctosigmoiditis and a submucoal tumor with a maximal diameter of 5 cm in the cecum. Computed tomography revealed a large, hypodense, cystic cylindrical structure extending to the pelvic space. For severe pain, she underwent partial resection of the cecum including the tumor in March 2008. Intraoperatively, the vermiform appendix was swollen like a sausage and compressing the cecum, which accounted for what appeared to be a submucosal tumor like a volcano by endoscopy...

BACKGROUND: Difficulty with the proximal lesion approach and durability of endoscopic ultrasonography (EUS) instruments usually limits its application for lower gaotrointestina (GI) lesions to locoregional staging of rectal cancer. This study investigated the value of colonoscopic miniprobe ultrasonography for differential diagnosis and treatment strategy in patients with colorectal subepithelial lesions (SEL). METHODS: Miniprobe ultrasonography was Performed in 40 consecutive patients with suspected colorectal SEL or residual lesions after endoscopic resection at one medical center by the same endoscopist (C-J Lin)...
