Diagnosis of primary appendiceal adenocarcinoma (PAA) is hindered by its rarity and largely asymptomatic nature. Appendiceal diverticulosis (AD) is equally rare. We report an unusual case of PAA presenting with perforated appendiceal diverticulitis, and discuss a review of the literature about its association, and its surgical and pathological implications. A middle-aged man was admitted with right iliac fossa (RIF) pain and a corresponding tender abdominal mass for 5 days. Computerised tomography (CT) scan demonstrated a thickened appendix with 3 cm abscess at its base...

Metastatic tumors of the appendix are rare. Endometrial cancer tends to metastasize by directly invading neighboring structures; the lung, liver, bones, and brain are common sites of distant metastasis. Herein, we present a case of a solitary endometrial metastatic tumor in the appendiceal mucosa without serosal involvement that mimicked a primary adenocarcinoma of the appendix. The patient who had undergone a radical hysterectomy for an endometrioid adenocarcinoma 3 years earlier presented to the hospital with a history of persistent right-lower abdominal pain...

We investigated whether obesity and socio-demographic factors at adolescence are associated with incident gastroenteropancreatic neuroendocrine tumors (GEP-NET).Our cohort included 2.3 million Israeli adolescents examined at ages 16 to 19 years between 1967 and 2010. The baseline database included sex, country of birth, residential socio-economic status (SES), body-mass index (BMI) and height. Participants were followed through linkage with the National Cancer Registry up to 2012. We identified 221 cases of GEP-NET (66 pancreatic, 52 gastric, 39 rectal, 27 appendiceal, 23 small bowel and 14 colonic)...

Appendiceal intussusception is a very rare condition with an estimated incidence of 0.01%. Most cases present in adults with chronic waxing and waning of symptoms over a period of weeks to months. We report a case of a 39-year-old Caucasian female with a 5-week history of worsening right-sided abdominal pain. Computed tomography revealed cecal thickening without visualization of the appendix. A colonoscopy revealed mild diffuse erythema and edema in the ascending colon as well as a mass within the lumen of the cecum...

Introduction The use of polymeric clips in securing the appendiceal stump has been increasingly reported as a viable alternative to current methods in emergency laparoscopic appendicectomy. We evaluated the operative outcomes following the use of polymeric clips versus endoscopic ligatures. The primary endpoint was operative time, with secondary outcomes including complications, inpatient stay, and cost analysis. Materials and methods Operative records were retrospectively analysed to identify patients undergoing laparoscopic appendicectomy between January 2014 and June 2015...

BACKGROUND Carcinoid tumor, benign, low-grade malignant, and high-grade malignant, can be associated with the release of vasoactive substances that cause symptoms including cutaneous flushing, diarrhea, and bronchospasm. In 50-60% of patients with carcinoid syndrome, the vasoactive substances cause fibrosis of the pulmonary and tricuspid heart valves which lead to regurgitation and right-sided heart failure. The right side of the heart is usually affected because monoamine oxidases in the lungs usually inactivate the vasoactive substances...

BACKGROUND: A distended, mucous-filled appendix is known as an appendiceal mucocele. They are a rare form of an appendiceal mass and develop from both benign and malignant processes. Mucoceles can develop secondarily to an obstruction, such as from a fecalith, scarring or, rarely, endometriosis. Only 12 cases of non-neoplastic appendiceal mucoceles caused by endometriosis have been previously described. The association between neoplastic appendiceal mucoceles in the presence of endometriosis is described for the first time in this report...

INTRODUCTION: The Malone antegrade continence enema (MACE) procedure remains an effective tool in providing independence to patients with refractory constipation. Appendiceal, ileal and colonic segments are all used depending upon the patient's individual anatomy and surgeon's preference. Unfortunately, MACE stomal stenosis (SS) remains a frustrating complication. It was hypothesized that SS is associated with the type of efferent limb used for MACE construction. OBJECTIVE: To perform a retrospective risk analysis of the pre-operative factors that correlated with postoperative stomal stenosis...

INTRODUCTION: Although appendicitis is a common disease, appendicitis concurrent with liver abscesses and sessile serrated adenoma/polyp (SSA/P) is rare. PRESENTATION OF CASE: A 69-year-old man presented with symptoms of abdominal pain and fever. Computed tomography (CT) revealed multiple liver abscesses and an enlarged appendix with a pseudotumoral appearance, which suggested acute appendicitis. In the emergency operation, ileocecal resection was performed for the perforated appendicitis with an inflammatory mass in the ileocecum...

Acute appendicitis (AA) develops in a progressive and irreversible manner, even if the clinical course of AA can be temporarily modified by intentional medications. Reliable and real-time diagnosis of AA can be made based on findings of the white blood cell count and enhanced computed tomography. Emergent laparoscopic appendectomy (LA) is considered as the first therapeutic choice for AA. Interval/delayed appendectomy at 6-12 wk after disease onset is considered as unsafe with a high recurrent rate during the waiting time...

BACKGROUND: Appendiceal mucinous adenocarcinoma is an extremely rare disease in clinical practice. Here, we report a case of unprecedented size that occupied the entire abdomen of a man. CASE PRESENTATION: A 49-year-old Chinese Han man presented with symptoms of abdominal distension. During a computed tomography imaging examination, a cystic-solid mass that occupied his entire abdominal cavity was detected. During exploratory laparotomy, an appendiceal tumor in his abdominal-pelvic cavity measuring 27...

Autoamputation of the appendix has previously been reported in the literature, but it is likely an unusual event. We report a 2-year-old male child who had previously undergone laparotomy and bowel resection for necrotizing enterocolitis. 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: Appendectomy has been the preferred treatment of acute appendicitis. However, extensive resection (ER) such as an ileocecal resection is sometimes needed. We analyzed the predictive factors of ER. METHODS: This was a retrospective study of 927 patients with acute appendicitis in 7 years. The data collected, including demographic characteristics, laboratory tests, computed tomography (CT) findings and days from onset. RESULTS: ER was performed in 40 patients (4...

Pseudomyxoma peritonei (PMP) is a rare disease that usually originates from mucinous neoplasms of the appendix and, less commonly, from extra-appendiceal tumors, but it may also be caused by synchronous primary mucinous tumors of the ovary and appendix. The current study discusses the case of a 73-year-old female who presented with progressively worsening indigestion and abdominal distension. Magnetic resonance imaging of the pelvis revealed a large cystic mass with a thin enhancing septa arising from the right ovary and ascites with scalloping of the liver surface...

Appendiceal neoplasms are uncommon tumors of the gastrointestinal tract that may manifest with symptoms of appendicitis, right lower quadrant pain, or palpable mass, leading to imaging or surgical intervention. The majority of appendiceal masses consist of primary epithelial neoplasms and neuroendocrine tumors (NETs). Epithelial neoplasms-mucinous and nonmucinous types-are more often detected at imaging than NETs due to their larger size and propensity for peritoneal spread and metastatic disease. Epithelial mucinous neoplasms are defined by the presence of mucin, detected at radiologic and pathologic examination...
