Signet ring cell carcinoma of the colon and rectum is rare, and most cases are detected at an advanced stage. We present a case of primary signet ring cell carcinoma detected at an early stage by magnifying endoscopy with narrow-band imaging (NBI) and crystal violet staining. A 73-year-old man visited our hospital for screening colonoscopy. Six years previously, he had undergone endoscopic submucosal dissection (ESD) for early gastric cancer. The pathological diagnosis was a well-differentiated adenocarcinoma, invading into the mucosa without lymphovascular invasion. Colonoscopy revealed a flat elevated lesion with a slightly depressed area, 20 mm in diameter, in the cecum. Further, magnifying endoscopy with NBI revealed that the surface pattern was slightly irregular and microvessels had a regular diameter and distribution in the margin of the lesion, but in the central part of the lesion, irregularity in the tumor surface pattern and form as well as in the diameter and distribution of microvessels was
Primary Signet-ring cell carcinoma (Linitus Plastica) of the colon and rectum is a rare form of adenocarcinoma of the large intestine and has been reported to have an extremely poor prognosis. We report a case of Primary Signet-ring cell carcinoma of the colorectum in a thirty one year old man presented in Surgical OPD of our hospital with chief complaints of persistent pain in abdomen and vomiting since two days. Since the prognosis of primary signet ring cell carcinoma (SRCC) is extremely poor (in view of more malignant behavior than ordinary colorectal carcinoma), early diagnosis and aggressive treatment strategy are necessary. ...

Primary signet cell carcinoma of the prostate is a rare histological variant of prostate malignancies. It is commonly originated from the stomach, colon, pancreas, and less commonly in the bladder. Prognosis of the classical type is worse than the adenocarcinoma of the prostate. Primary signet cell adenocarcinoma is diagnosed by eliminating the adenocarcinomas of other organs such as gastrointestinal tract organs. In this case report, we present a case with primary signet cell adenocarcinoma of the prostate who received docetaxel chemotherapy because of short prostate specific antigen doubling time ...

Primary signet-ring cell carcinoma (PSRCC) is a rare variation of adenocarcinoma of the urinary bladder. English literature review on pubmed reveals less than 100 cases reported. Adenocarcinoma constitutes 2% of all bladder cancers with the majority being metastatic rather than primary[1]. A study of 713 cases of primary bladder tumor in Sweden revealed 4 signet ring cell carcinomas, only 0.6% [2]. Another series of 715 bladder cancers in Germany revealed 18 adenocarcinomas but only one with the classic histologic pattern of signet-ring cell carcinoma [3]. Signet-ring cells are much more commonly described in primary adenocarcinoma of the stomach, colon, breast or gallbladder and malignancies of these organs should be excluded before diagnosing PSRCC of urinary bladder [3]. A 3:1 male to female predominance has been shown [4], but in male patients, it is especially necessary to rule out prostatic adenocarcinoma as a possible site of origin [5].. Most patients present in middle-age with symptoms ...
Hi Shelly,. I was diagnosed with Stage IV gastric cancer in 2012. We did 8 rather aggresive chemo treatments over a 4 month period which were effective and I tolerated them better than most. I would not have been eligible for surgery if the chemo had not helped shrink the tumor but thank God it did. There were a few weeks between the end of chemo and the surgery when I felt very good.. My surgery was January 2013, a total gastrectomy with HIPEC (100+ degree chemo circulated through the abdominal cavity). The recovery was difficult at times and the help of family and friends kept me strong and positive. After a few weeks, I had 4 more chemo sessions. They were a little harder on me than the first 8. I am now over 2 years with clean scans.. While everyones case is different, I will answer any questions you have to the best of my ability. Best of luck to your Dad & you. ...

Gastric signet ring cell carcinoma (SRCC) is a rare form of highly malignant adenocarcinoma. It is an epithelial malignancy characterized by the histologic appearance of more than 50% of cells as signet ring cells filled with mucin. The incidence of SRCC is rising,[1],[2] therefore, the diagnosis of these cancers in the early stage is important as it is the only stage that curative measures can be done. A 49-year-old female was hospitalized due to epigastric pain, postprandial bloating for 3 months. Upper gastrointestinal endoscopy with narrow band imaging (NBI) showed 1 ...
TY - JOUR. T1 - Histologic and immunohistochemical differences between hereditary and sporadic diffuse gastric carcinoma. AU - Lee, Hee Eun. AU - Smyrk, Thomas Christopher. AU - Zhang, Lizhi. PY - 2018/4/1. Y1 - 2018/4/1. N2 - We aimed to identify histopathologic features unique in hereditary diffuse gastric cancer (HDGC) by comparing with its sporadic counterpart (SDGC). 11 patients with confirmed CDH1 mutation who were found to have HDGC in a prophylactic total gastrectomy were collected. Median age of HDGC patients was 39 years (range 24-57). All HDGC cases had intramucosal signet ring cell carcinoma. Twenty-three invasive tumor foci from 7 patients with HDGC were available for ancillary studies, and we evaluated each focus separately. Almost all foci (20/23) showed two distinct tumor cell populations, namely, large signet ring cells and small signet ring cells. The large cells were located just beneath the surface epithelium and were positive for mucicarmine and pCEA, while the small cells ...
2 MANECs are rare entities known to be associated with biological aggressiveness and poor patient survival, but otherwise remain incompletely characterized.3 In a recent study that compared CRC-NE to conventional colorectal carcinoma, CRC-NE was more frequently located in the right colon (76% vs. 46%), more often presented with metastasis (59% vs. 18%) and often had perineural (68%), lymphatic (97%), and venous (62%) invasion and high tumor budding (71%). BRAF V600E mutation was more common in CRC-NE compared with conventional CRC (53% vs. 12%). Neuroendocrine differentiation, high stage, BRAF mutation without microsatellite instability, and signet ring histology were all associated with poor overall survival.4 In the same study, CRC-NE was further divided into large cell neuroendocrine carcinoma (LCNEC), MANEC composed of LCNEC and conventional adenocarcinoma (MANEC-conventional type), and MANEC composed of LCNEC and signet ring cell carcinoma (MANEC-signet ring type). MANEC-signet ring type ...
TY - JOUR. T1 - Different methylation profiles between intestinal and diffuse sporadic gastric carcinogenesis. AU - Yang, Misuk. AU - Kim, Hyunsoo. AU - Cho, Meeyon. PY - 2014/1/1. Y1 - 2014/1/1. N2 - Objective: Gastric cancer (GC) is histologically classified into intestinal type and diffuse type, and diffuse type cancer can be further subdivided into poorly differentiated carcinoma (PDC) and signet ring cell carcinoma (SRCC). Recent evidence suggests that early SRCC is an initial, differentiated form of diffuse GC that may evolve into PDC. This study aimed at identifying the molecular features of epigenetic methylation changes in histologic differentiation status of GC. Methods: Included in this study are 149 samples of paraffin-embedded tissues and 115 fresh endoscopically biopsied tissues. Multiple paraffin tissues involving normal (n=. 22), dysplasias (GDs, n=. 39), differentiated cancers (DCs, n=. 35), PDCs (n=. 33) and SRCCs (n=. 20) were included as an experimental group. For the ...
Immunohistochemical distributions of cathepsins D and E were determined in normal mucosa, metaplastic, dysplastic, and cancerous lesions of the human stomach. Cathepsins D and E were localised in the foveolar epithelium and parietal cells of the normal gastric mucosa, but their intracytoplasmic distributions were different - cathepsin E distribution was even and diffuse in the cytoplasm while cathepsin D was found in coarse intracytoplasmic granules. Chronic inflammation and ulcer did not influence the distribution of these enzymes. No positive staining was obtained in the incomplete type of intestinal metaplasia, dysplasia, and well differentiated adenocarcinoma. Tumour cells of signet ring cell carcinoma and poorly differentiated adenocarcinoma cells, however, gave strong and diffuse stainings for cathepsins D and E in the cytoplasm. The results suggest that the distribution of cathepsins D and E is related to each specialised function of the foveolar epithelium and the parietal cells, and ...
This case is of interest for three reasons: the site of origin in the right colon (80% of cases reported develop distally to the splenic flexure), a biopsy previously taken from the mucosa demonstrated the presence of a signet ring cell carcinoma (endoscopic biopsies do not provide a conclusive diagnosis in the majority of cases reported) and hyaline with sparse amyloid nodules were detected in the extensive, dense fibrous tissue intermingled with tumour cells ...
Researchers are divided in their views regarding the most common site of the first lesion in sporadic CRC among young patients: Some of them reported that CRC was most often located in the ascending colon [7,8], whereas others noted the descending colon or rectum as the most common location, which is the same for adult patients [9]. In the present study, the descending colon or rectum was the most frequent location (16/19, 84.2%). Regarding histological subtype, adenocarcinoma is the most common type, being found in 85% of adult CRC patients, followed by mucinous adenocarcinoma (10%-15%) and signet ring cell type (1%) [10]. Unlike CRC in adults patients, however, in young patients, the most common types were mucinous adenocarcinoma (6/19, 31.5%) and signet ring cell type (2/19, 10.5%). Normally, mucinous adenocarcinoma and signet ring cell type result in poorer outcomes compared with adenocarcinoma. Poor outcomes were also found in this study as 4 of 6 patients (66%) with mucinous adenocarcinoma ...
I also have signet ring adenocarcinoma. Yes, it can be very aggressive. I have been told that the only thing that can be done for me is to watch it ... And to from time to time do a laparoscopic surgery to see if it has progressed within the abdominal cavity. They think mine originated in the appendix but grew into the colon. There are several of us here who have the same pathology. I just had a laparoscopic surgery 2 weeks ago and everything looks good. We will find out for sure today...we have the follow-up with the surgeon. They did do a saline belly wash...and took that fluid to be tested For signs of cancer Return. But, as far as the dr could see everything looked good. The plan right now is to continue to monitor cancer markers and then do another pt/ct scan in 6 months. I had the rt hemicolectomy last year followed by 6 months of Folfox.. you need to find out, if possible, the origin of the cancer....quite often it is appendiceal. If it is, then he really needs to be seeing an appendix ...

For CDH1 mutation carriers, the current consensus recommendation is to consider prophylactic gastrectomy, performed by an expert surgeon, in the third decade of life. This recommendation is made because, although asymptomatic CDH1 mutation carriers have been identified to have multifocal tiny signet ring cell cancers, these are not reliably detected at gastroscopy, even with advanced imaging techniques.. The risk of gastric cancer is less than 1% under the age of 20 years, so annual surveillance gastroscopy with targeted and random biopsies, according to an international protocol, is recommended for CDH1 mutation carriers aged 16-20 years.. Breast surveillance guided by a specialist with annual breast MRI (which can be combined with mammography) starting at age 30 years is recommended for women with a CDH1 mutation.. Carrying a CDH1 mutation has significant implications. Expert care is important but not always easy to access. Probands and families presenting purely with breast cancer in whom a ...

Results Non-polarised E-cadherin-negative parietal cells and proton pump-negative atypical foci were observed in DCKO mice. Intramucosal cancers and invasive cancers composed of poorly differentiated carcinoma cells and signet ring cells, histologically very similar to those in humans, were found from 6 to 9 months, respectively. Fatal DGC developed at 100% penetrance within a year, frequently metastasised to lymph nodes, and had tumourigenic activity in immunodeficient mice. Gene expression profiles of DGC in DCKO mice also resembled those of human DGC, and mesenchymal markers and epithelial-mesenchymal transition-related genes were highly expressed in mouse DGC as in human DGC. ...

Network models are widely used to describe complex signaling systems. Cellular wiring varies in different cellular contexts and numerous inference techniques have been developed to infer the structure of a network from experimental data of the networks behavior. To objectively identify which inference strategy is best suited to a specific network, a gold standard network and dataset are required. However, suitable datasets for benchmarking are difficult to find. Numerous tools exist that can simulate data for transcriptional networks, but these are of limited use for the study of signaling networks. Here, we describe SiGNet (Signal Generator for Networks): a Cytoscape app that simulates experimental data for a signaling network of known structure. SiGNet has been developed and tested against published experimental data, incorporating information on network architecture, and the directionality and strength of interactions to create biological data in silico. SiGNet is the first tool to simulate ...

March 25, 2014 - Nursing students raising funds for fellow student battling cancer by selling bracelets. Jessica Girard is a dear friend of ours and a member of our nursing class. She is extremely passionate and warm hearted friend, who makes an impact on every person she meets. At the age of 20, she was unfortunately diagnosed on December 27th 2012 with a rare form of stage 4 colon cancer (Signet Ring Adenocarcinoma). Shortly after her diagnosis, Jessica learnt that the cancer had spread to reproductive organs. Jessica has spent the majority of the past year and a half in hospitals for multiple surgeries and chemotherapy treatments. In January of 2014, Jessica was declared in remission. Three weeks later Jessica received tragic news described by her as a day where her world stopped in its tracks, as she was re-diagnosed with cancer. Since this re-diagnosis Jessica has spent almost everyday in the hospital in and outside of Canada. She is currently traveling back and forth from Windsor to London ...

Introduction. Accurate diagnosis of melanoma is the most important prerequisite for optimal clinical management. Examination of hematoxylin and eosin (H&E) stained sections using conventional microscopy remains the gold standard for diagnosis of melanocytic lesions and as such most of the criteria used in the American Joint Committee on Cancer (AJCC)/College of American Pathologists (CAP) recommendations for reporting specimens with melanoma are based on routine examination of histologic slides.1 However, when lesions exhibit architectural and cytologic features that overlap both melanocytic nevi and melanomas, histologic examination alone may be insufficient for diagnosis. Being one of the ultimate histologic mimickers, melanoma may present in a range of histologic variants with spindle cell, desmoplastic, clear cell, balloon cell, signet ring cell, small cell, plasmacytoid and rhabdoid phenotypes.2-4 Rarely, even establishing melanocytic lineage of a tumor may become a challenging task, ...
E-cadherin (epithelial cadherin, CDH1, OMIM# 192090) is a member of the cadherin family of adhesion molecules, which are transmembrane glycoproteins mediating calcium-dependent cell-cell adhesion1. Germline mutations in the CDH1 gene have been demonstrated to underlie in diffuse gastric cancer (DGC) in various ethnic backgrounds 2, 3, 4. CDH1 germ line mutations have also been identified in a small portion of early onset DGC patients without a family history 5, 6, 12. Associations between CDH1 germ line mutations and both lobular breast cancer and signet ring carcinoma of the colon have been reported in DGC families 7, 8, 9. DGC is a highly penetrant autosomal dominant disorder that has been reported to occur in many ethnicities. The offspring of an affected individual has a 50% risk of also being affected. The estimated cumulative risk of gastric cancer by age 80 years is 67% (95% CI: 39-99) for men and 83% (95% CI: 58-99) for women10. Women also have a 39% risk for lobular breast cancer10. ...

The presence of signet ring morphology should alert the pathologist to consider the diagnosis of primary and metastatic malignancies in the prostate; however, it does not exclude the possibility of nephrogenic adenoma. Lesions in association with the urethra forming small tubules and showing PAX8 positivity have a differential diagnosis that should include nephrogenic adenoma and clear cell carcinoma. In this case, a low Ki67 index, lack of atypia, small size and the typical prior history of surgical trauma favored the interpretation of the lesion as nephrogenic adenoma ...
