OBJECTIVES: To evaluate whether routine appendectomy is necessary in all patients with mucinous borderline ovarian tumor (mBOT) or mucinous ovarian cancer (MOC) who undergo gynecologic surgery. METHODS: The database of Qilu Hospital was searched for women who underwent appendectomy in a primary surgery for an ovarian tumor between June 2005 and June 2015 and whose final diagnosis was mBOT, MOC or primary appendiceal tumor. A retrospective review was performed, as well as a meta-analysis of the literature to further validate the findings...

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...

Malignant neoplasms of the appendix are rare and represent less than 1% of gastrointestinal cancers. Goblet cell carcinoids (GCC) tumors are a distinctive group of heterogeneous appendiceal neoplasm that exhibit unique clinical and pathologic features. This review focuses on the current diagnostic procedures, pathogenesis, possible signaling mechanisms and treatment options for GCC. Perspectives for future research are discussed. The tumor likely arises from pluripotent intestinal epithelial crypt base stem cells...

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...

PURPOSE: Rare cancers represent 22% of all tumors in Europe; however, the quality of the data of rare cancers may not be as good as the quality of data for common cancer. The project surveillance of rare cancers in Europe (RARECARE) had, among others, the objective of assessing rare cancer data quality in population-based cancer registries (CRs). Eight rare cancers were considered: mesothelioma, liver angiosarcoma, sarcomas, tumors of oral cavity, CNS tumors, germ cell tumors, leukemia, and malignant digestive endocrine tumors...

The appropriate therapy for metastatic breast cancer must be selected based on the immunohistochemical phenotype of the cancer. However, biopsy for metastatic lesions is difficult. We herein report a patient with incidental appendicitis caused by a metastatic breast cancer which was successfully treated with effective therapy chosen based on the pathological diagnosis obtained on resection. The patient was a 56-year-old female with right breast cancer and an immunohistochemical status of estrogen receptor (ER) (+), progesterone receptor (PgR) (+), human epidermal growth factor receptor 2 (HER2) (3+), and Ki67 40 %...

The incidence of epithelial skin neoplasms, such as squamous cell carcinoma and basal cell carcinoma is significantly increasing worldwide. Leisure time solar UV exposure is causative in the overwhelming majority of cases in the general population; however, occupational exposure is responsible for a certain percentage of cases. Employees with a relevant exposure to polycyclic aromatic hydrocarbons in soot, raw paraffin, coal tar, anthracene, pitch or similar substances, to sunlight in outdoor occupations as well as to arsenic and ionizing radiation have a significantly increased risk to develop occupational skin cancer compared to the general population...

Telomeres shorten with physiological aging but undergo substantial restoration during cancer immortalization. Increasingly, cancer studies utilize the archive of formalin-fixed, paraffin-embedded (FFPE) tissues in diagnostic pathology departments. Conceptually, such studies would be confounded by physiological telomere attrition and loss of DNA integrity from prolonged tissue storage. Our study aimed to investigate these two confounding factors. 145 FFPE tissues of surgically-resected, non-diseased appendixes were retrieved from our pathology archive, from years 2008 to 2014...

BACKGROUND: Appendiceal cancer is extremely rare with excellent survival after curative resection. There is a concern for the development of additional cancers in survivors of appendiceal cancer. However, existing data is limited to small anecdotal reports on appendiceal carcinoid only. We aim to investigate the risk of subsequent malignancies in patients with appendiceal carcinoma and correlate the risk according to patient and clinical characteristics. METHODS: We identified 3788 patients with appendiceal cancer from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database between 1992 and 2011...

Peritoneal disseminations from lung cancer are difficult to detect during the patient's clinical course. Therefore, complications of this condition are unclear. We report a case in which peritoneal dissemination from lung cancer complicated appendicitis. A 74-year-old man with lung cancer who was receiving maintenance therapy presented at our hospital because of abdominal pain. It was the seventh day after the 14th cycle of maintenance therapy with bevacizumab. He was diagnosed with acute appendicitis. The resected appendix showed acute appendicitis complicated by appendiceal metastasis from lung cancer...

BACKGROUND: Ulcerative colitis (UC) promotes cancer, and can be ameliorated by early appendicectomy for appendicitis. The aim of the study was to explore the effect of appendicectomy on colitis and colonic neoplasia in an animal model of colitis and a cohort of patients with UC. METHODS: Five-week old IL10/Nox1(DKO) mice with nascent colitis and 8-week-old IL10/Nox1(DKO) mice with established colitis underwent appendicectomy (for experimental appendicitis or no appendicitis) or sham laparotomy...

A new histological classification of neuroendocrine tumors (NETs) was established in WHO 2010. ENET and NCCN proposed treatment algorithms for colorectal NET. Retrospective study of NET of the large intestine (colorectal and appendiceal NET) was performed among institutions allied with the Japanese Society for Cancer of the Colon and Rectum, and 760 neuroendocrine tumors from 2001 to 2011 were re-assessed using WHO 2010 criteria to elucidate the clinicopathological features of NET in the large intestine. Next, the clinicopathological relationship with lymph node metastasis was analyzed to predict lymph node metastasis in locally resected rectal NET...

Although common side effects of regorafenib include hand-and-foot syndrome and diarrhoea, the incidence of gastrointestinal perforation is reportedly unknown. We describe our experience with the case of a 65-year-old woman treated with regorafenib as a third-line therapy for progressive caecal cancer with multiple hepatic metastases after 4 and 6 courses of systemic mFOLFOX6 + bevacizumab (BV) and FOLFIRI + BV chemotherapy, respectively. The patient used regorafenib for 32 days but visited our hospital with abdominal pain during the second course...

We report a 32-year-old patient who underwent laparoscopy with classical symptoms and signs of acute appendicitis. An inflamed, edematous and non-perforated appendix, also a large amount gelatinous ascites, omental and peritoneal implants were seen. Appendectomy was performed and multiple biopsies were taken from omentum and peritoneum for definitive diagnosis. Histopathologic diagnosis was a metastatic gastric signet-ring cell carcinoma (GSRCC) involving appendix and other specimens. A flat lesion involving corpus to antrum was diagnosed by gastroscopy and GSRCC was verified histopathologically in a tertiary centre and the case evaluated as stage IV gastric carcinoma...

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...
