Appendiceal tumors are rare, late diagnosed neoplasms that may not be differentiated from adnexal masses even by advanced imaging methods and other diagnostic procedures. They may be asymptomatic and remain undiagnosed until surgery. We report a case of an 80-year-old postmenopausal woman presenting with a pelvic mass and a history of weight loss. The patient underwent laparotomy which revealed an appendiceal mucocele, for which she received a full oncological procedure. The histology report showed a low-grade appendiceal mucinous neoplasm, and the patient underwent six cycles of chemotherapy...

BACKGROUND: It has been increasingly recognized that appendiceal mucinous neoplasm with peritoneal dissemination is not a homogenous disease. OBJECTIVE: This study aimed to examine the impact of different histological subtypes on survival of a large cohort of patients with appendiceal mucinous neoplasms uniformly treated by cytoreductive surgery and intraperitoneal chemotherapy. DESIGN: This was a retrospective study of prospectively collected data of patients with peritoneal dissemination of appendiceal neoplasm who underwent cytoreductive surgery and intraperitoneal chemotherapy...

Low-grade appendiceal mucinous neoplasms (LAMNs) are neoplastic lesions with potential progression to pseudomyxoma peritonei (PMP). In most cases, diagnosis is made because of suspected acute appendicitis or incidentally by computed tomography (CT). However, incidental diagnosis during colonoscopy is rare. We present the case of a 63-year-old man with a LAMN type 1 lesion, diagnosed at routine colonoscopy for surveillance of ulcerative colitis. Because in earlier surveillance colonoscopies, this lesion was misinterpreted as fecal polution, for the first time, this case describes retrospectively a 3-year endoscopic follow-up of LAMN type 1, underlining the benign course of these kind of lesions compared to type 2 lesions with submucosal infiltration...

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...

We encountered a case of giant appendiceal mucinous neoplasm that was treated with laparoscopic surgery. The patient was a 77-year-old man with constipation. Lower endoscopy demonstrated a giant SMT-like tumor in the cecum, and abdominal computed tomography revealed a giant appendiceal mucinous neoplasm and nearby lymph nodes swelling. Hematological examination showed an elevated serum CEA level. We performed laparoscopic ileocecal resection for a definite diagnosis and treatment. The postoperative course was uneventful...

Low-grade appendiceal mucinous neoplasm(LAMN)is a rare disease. In consideration of consistency with the 2010WHO Classification, LAMNwas classified in the Japanese Classification of Colorectal Carcinoma 8th edition. The present study involved 14 patients with LAMNover a 5-year period. The preoperative diagnosis was made as mucocele of the appendix in 9 cases. Operative interventions included ileocecal resection in 6 cases(laparoscopic; 3 cases)and appendectomy in 8 cases (laparoscopic; 6 cases). Histopathologically, there was no LNpositive case...

Appendiceal mucoceles (AMs) infrequently arise from an underlying malignancy. Treatment has progressed toward a less aggressive approach over time; they can be managed by appendectomy-only unless pathology reveals malignancy. The ultimate goal of management is to prevent AM rupture, avoiding the syndrome of pseudomyxoma peritonei.

BACKGROUND: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is a treatment option for peritoneal surface malignancies. The ability to detect microscopic foci of peritoneal metastasis intraoperatively may ensure the completeness of cytoreduction. In this study, we evaluated the suitability of a hand-held cathepsin-based fluorescent imaging system for intraoperative detection of appendiceal and colorectal peritoneal metastasis. METHODS: Peritoneal tumors and normal peritoneal tissues were collected from patients with appendiceal and colorectal peritoneal metastasis...

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...

Primary appendiceal mucinous lesions are uncommon and represent a spectrum from nonneoplastic mucous retention cysts to invasive adenocarcinoma. Low-grade appendiceal mucinous neoplasms (LAMNs) represent an intermediate category on this spectrum and can be classified according to whether or not they are confined to the appendix. Although LAMNs are frequently confined to the appendix, they can also spread to the peritoneum and clinically progress as pseudomyxoma peritonei (i.e., mucinous ascites). Thus, the appropriate classification of appendiceal primary neoplasia is essential for prognosis and influences clinical management...

BACKGROUND: Mucinous appendiceal neoplasms (MAN) with peritoneal dissemination is treated as a standard of care using cytoreductive surgery and hyperthermic perioperative chemotherapy. The extent of the resection of peritoneal surfaces and visceral structures is generally well defined. Exception to this consensus regarding structures to be removed are the right colon and adjacent ileocolic lymph nodes. METHODS: From a prospectively maintained database, all patients with a histologic diagnosis of peritoneal mucinous carcinoma (PMCA) who underwent complete cytoreductive surgery were assessed for the presence versus absence of adenocarcinoma in lymph nodes within the appendiceal mesentery and/or in the lymph nodes of the ileocolic group...

BACKGROUND: There is little evidence for the use of early postoperative intraperitoneal chemotherapy (EPIC) in patients with low-grade appendiceal mucinous neoplasms (LAMNs) with pseudomyxoma peritonei (PMP). This study aims to assess the outcomes regarding the use of EPIC in a large cohort of patients with LAMNs with PMP uniformly treated by cytoreductive surgery (CRS) and perioperative intraperitoneal chemotherapy (PIC), all of whom received hyperthermic intraperitoneal chemotherapy (HIPEC), and most of whom also received EPIC...

Heterotopic ossification occurring to low-grade appendiceal mucinous neoplasm (LAMN) (pseudomyxoma peritonei) is extremely rare. The pathogenetic mechanism of the tumor-related heterotopic bone formation remains as yet unconfirmed. Here, we describe a rare case of LAMN with ossification in a 72-year-old woman, and concentrate on the etiology of heterotopic ossification by the immunohistochemical evaluation of the novel markers such as BMP9, osteocalcin, and osteopontin. BMP9 is one of the most effective osteogenetic proteins...

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...

BACKGROUND: Low-grade appendiceal mucinous neoplasm of uncertain malignant potential are poorly understood lesions characterized by extraluminal mucin or fibrosis with neoplastic cells confined to the appendiceal lumen. The purpose of this study is to investigate the clinical and pathologic parameters of these lesions to optimize our understanding and management of these tumors. METHODS: Subjects with these tumors were identified from the appendiceal tumor databases at the University of Texas MD Anderson Cancer Center...

INTRODUCTION: The prognosis of appendiceal mucinous neoplasms (AMN) is directly related to their histopathology. Existing classification schemes encompass tumors with widely divergent clinical behaviors within a single diagnosis, making it difficult for clinicians to interpret pathology reports to counsel patients on optimal management. We sought to examine pathology reports generated for AMN for inclusion of essential histologic features. METHODS: Pathology reports of appendectomy specimens with a diagnosis of AMN (2002-2015) at our center ("internal") and from referring institutions ("external") were retrospectively reviewed for inclusion of the following 5 essential items: layer of invasion, mucin dissection (low grade neoplasms only), perforation, margins, and serosal implants...

BACKGROUND: Disseminated peritoneal adenomucinosis (DPAM) patients often have a history of appendectomy with identification of an incidental mucinous neoplasm (low-grade appendiceal mucinous neoplasm (LAMN)). The rate of developing DPAM is not well established. METHODS: Twenty-two patients with incidental LAMN were identified and monitored with cancer markers and CT every 4-6 months. Laparoscopy with peritoneal washing was performed in patients either in the event of radiographic disease or after 12 months in absence of radiographic disease...

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...

BACKGROUND: Tumours of appendix, including classic carcinoid tumour (CCT), goblet cell carcinoid (GCC), low-grade appendiceal mucinous neoplasm, high-grade appendiceal mucinous neoplasm/mucinous carcinoma (MCA) and non-mucinous adenocarcinoma (NMA), show different and sometimes mixed morphological features. It was hypothesised that these tumours originate from common tumour stem cell(s) with potential of various cell lineage differentiation. In normal intestinal epithelium, absorptive lineage (enterocytes) differentiation is driven by Notch-Hes1 pathway, while secretory lineage is driven by Wnt-Math1 pathway and further separated by different downstream signallings into three sublineages (Gfi1-Klf4/Elf3 for goblet cells, Gfi1-Sox9 for Paneth cells and Ngn3-Pdx1/Beta2/Pax4 for enteroendocrine cells)...

Mucinous neoplasms of the urinary tract are very rare. We present a 63-year-old-women who had a sessile papillary villous tumor in urinary bladder. Although transurethral resection of the bladder tumor (TURBT) was performed, the villous tumor repetitively recurred and gradually spread to the entire surface of bladder lumen. Histopathologic and immunohistochemical examination showed that the lesion was very similar to low-grade mucinous neoplasm arising in appendix vermiformis. There are no reports on appendiceal metaplasia of urinary bladder mucosa...
