Access to the bypassed portion of the stomach after Roux-en-Y gastric bypass remains a challenge. We present a case of 64-year-old woman who presented with gastric outlet obstruction. We used a novel endoscopic technique to access the bypassed stomach by creating a jejunogastrostomy using a specialized stent, which allowed the insertion of a pediatric gastroscope to examine the bypassed portion of the stomach. Stomach biopsies revealed poorly differentiated adenocarcinoma with signet cell features.

Up to 10% of patients with visceral malignancies develop skin metastases during their clinical course and these metastases constitute about 2% of all skin cancers. Skin metastasis may be the first sign of a clinically silent visceral cancer or represent recurrence of an internal malignancy. In both situations, they are associated with poor prognosis, which can partly be attributed to underdiagnosis. In this paper, a case of relapsing gastric adenocarcinoma, which manifested itself as asymptomatic cutaneous papules and nodules on a patient's head and neck, is reported and histopathological approach to the cutaneous lesions containing signet-ring cell is briefly reviewed...

BACKGROUND: Endoscopic submucosal dissection (ESD) is not considered an appropriate treatment for undifferentiated early gastric cancer (UEGC) due to the higher risk of nodal metastases. We aimed to investigate predictive factors for nodal metastases in UEGCs, determine whether the tumor histology is an independent factor for it, and explore whether ESD is applicable for UEGC. METHODS: We reviewed the medical records of 1837 patients who underwent curative gastrectomy for poorly differentiated adenocarcinoma, signet ring cell carcinoma, and a mixed type of both tumors between 2008 and 2012...

Outcomes of patients with gastric cancer who exhibit positive peritoneal lavage cytology findings (CY(+) ) vary by diagnostic methods because of quantitative and qualitative cancer cell diversity. This study sought to establish practical diagnostic criteria for performing curative resections, based on peritoneal lavage cytology findings in gastric cancer patients. We enrolled 1028 patients with gastric cancer who underwent R0/1 (n=911) or R2 (n=117) resections and analyzed relationships between cancer cell findings in peritoneal lavage fluid and clinicopathological factors in the R0/1 group...

An 80 year-old female presented with ductal breast carcinoma (stage II) three years ago, complained of asthenia and iron-deficiency anemia. No diagnosis was obtained after conventional endoscopy and iron supplements were indicated. Ten months later visible digestive hemorrhage was presented. Upper and lower endoscopy was repeated but non-diagnosis was obtained. Thus, video capsule endoscopy was indicated identifying a stenotic lesion arising in the mucosa of distal jejunum. Histopathological examination revealed a poorly mucinous differentiated signet-ring cell adenocarcinoma with an intense peri-tumoral lymphoid (Crohn´s-like lymphoid reaction) and lympho-vascular infiltration with no nodal metastases (pT3N0;7ª edition TNM classification)...

BACKGROUND: Gastric cancer is a heterogeneous disease with variable presentation between racial and ethnic groups. Staging laparoscopy (SL) detects occult metastases not visible on cross-sectional imaging and therefore improves staging. It remains unclear how differences in race and ethnicity affect disease presentation and the yield of SL. METHODS: We performed a retrospective review of a prospectively maintained database to identify patients with gastric cancer treated with curative intent at our institutions from 2008 to 2015...

A nonsmoker 45-year-old woman, presented with a solid right ovarian mass. Microscopic examination revealed heterogeneous histology with tubular formations and extensive signet ring cell component that resembled the usual appearance of metastatic gastric carcinoma to the ovary. Moreover, the histology also showed solid nests of cells with a microvacuolated basophilic cytoplasm similar to those found in adenosquamous cervical carcinoma of glassy cell type. However, analysis of the patient's past history revealed a lung adenocarcinoma, diagnosed 4 years before, which prompted an immunohistochemical differential diagnosis, showing a strong expression for TTF-1 and Napsin A...

BACKGROUND/AIMS: South Asia is an enigma for gastric cancer (GC) because it is a low risk region with a high prevalence of Helicobacter pylori (H. pylori) infections. We evaluated the trend of GC clinical presentation and risk factors in patients with dyspeptic symptoms. MATERIALS AND METHODS: The medical records of patients, coded by the international classification of diseases (ICD-10-CM, 2015, Diagnosis Code C16.9) for malignancies of stomach diagnosed by esophagogastroduodenoscopy (EGD) and histopathology, were studied...

The clinicopathological characteristics and prognosis of gastric mucinous adenocarcinoma (MAC) and signet ring cell carcinoma (SRC) are still controversial. We designed our study to evaluate the clinicopathologic features and prognosis of MAC, SRC and ordinary gastric adenocarcinoma (OGAC) by analyzing the Surveillance, Epidemiology, and End Results (SEER)-registered database. The 5-year overall survival (OS) of patients with SRC was significantly lower than that of patients with MAC (P = 0.001) and OGAC (P < 0...

Colonic metastases from gastric cancer are a rare phenomenon and sparsely reported in the literature. We report a case of a 59-year-old woman who presented with vague abdominal symptoms and initial computer tomography (CT) imaging suggestive of a colonic apple-core lesion with serial colonoscopic biopsies diagnostic of metastatic signet ring cell gastric adenocarcinoma. This case is unique given the evolving CT and endoscopic findings that suggested a regression in colonic wall thickening in the setting of 5-aminosalicylic acid (5-ASA) use prior to histologic diagnosis...

Ménétrier's disease, also known as hyperplastic protein-losing gastropathy, is a rare, idiopathic, acquired, premalignant condition associated with gastric carcinoma. Its association with signet ring cell cancer of the stomach has been previously reported only twice. We present the third case of histologically confirmed concurrent Ménétrier's disease with signet ring carcinoma of the stomach, interrogated by esophagogastroduodenoscopy and endoscopic ultrasound.

Background and study aims: Hereditary diffuse gastric cancer (HGGC), an autosomal dominant tumor-syndrome, accounts for 1 % to 3 % of gastric cancers worldwide. Presumably 30 % to 40 % of all patients fulfilling the clinical guidelines for HDGC are carriers of a pathogenic mutation in the CDH1 gene. Patients often show multiple foci of signet ring cell carcinoma at early age and are advised to undergo prophylactic total gastrectomy (PTG). Our aim was to improve the endoscopic detection of HDGC by using an enhanced endoscopic protocol...

Russell bodies gastritis is a very rare disease, with few cases reported in literature, and characterized by the finding of plasma cells with eosinophilic intracytoplasmic inclusions in the gastric mucosa, called Mott cells. Although it has been partnered since its first description to Helicobacter pylori infection, it is important to considered differential diagnoses such as lymphoplasmacytic lymphoma, mucosa-associated lymphoid tissue (MALT) lymphoma, plasmacytoma and signet ring cell carcinom. In this case report, we address a patient with histologic confirmation and her follow up...

The paper presents the case of a male patient, hospitalized for acute abdomen due to perforated callous ulcer. Though the clinical appearance suggested a benign pathology, the histopathological exam of the resection piece showed multicentric early gastric carcinoma, signet ring cell type. At the patient's request, total gastrectomy was not performed, a conservative solution being chosen instead. Superior digestive endoscopy with biopsy and oncological dispensarization was performed one month after surgery, then at every 6 months...

A 52-year-old woman presented with stage IIB primary breast cancer (cT2N1M0), which was treated using neoadjuvant chemotherapy (epirubicin, cyclophosphamide, and paclitaxel). However, the tumor persisted in patchy areas; therefore, we performed modified radical mastectomy and axillary lymph node dissection. Routine endoscopy at 8 months revealed a depressed lesion on the gastric angle's greater curvature, and histology revealed signet ring cell proliferation. We performed endoscopic submucosal dissection for gastric cancer, although immunohistochemistry revealed that the tumor was positive for estrogen receptor, mammaglobin, and gross cystic disease fluid protein-15 (E-cadherin-negative)...

Signet ring cell carcinoma (SRC) more commonly presents as metastatic disease and renders patients to be considered for chemotherapy. While treatment options are limited overall, trastuzumab has been shown to be effective for HER2 positive SRC cases. The current algorithm for HER2 evaluation heavily relies on positive membrane-specific staining by immunohistochemistry (IHC), but several anecdotal reports have suggested that SRCs may be susceptible to misinterpretation due to non-specific staining in the marginated cytoplasm with/without nucleus...

Krukenberg tumours are rare metastatic tumours of the ovaries characterized by the presence of mucin-producing neoplastic Signet Ring Cell Carcinoma (SRCC). At first glance, this tumour may be confused with a primary ovarian tumour. Surgery and chemotherapy combination have led to improvement in prognosis, but it still remains severe. We report the case of a 60-year-old woman with a Krukenberg tumour rising from a low differentiated gastric adenocarcinoma. The patient was clinically stable for 26 months after surgery until she experienced a prompt decline and died of cerebral haemorrhage within two weeks...

BACKGROUND: Bariatric surgery has increased in popularity, with Roux-en-Y Gastric Bypass (RYGB) being one of the most frequently performed. This leads to many cases in which the stomach is removed from routine gastroscopy access, sometimes being a major source of concern. Performing enteroscopy in these patients is technically difficult. We present our experience with 24 cases in which the aim was to access the detached stomach. METHODS: Retrospective analysis on RYGB enteroscopy procedures aimed to access the detached stomach...

Treatment algorithm has not been established for early gastric cancer with signet ring cell carcinoma (SRC), which has a reported low rate of lymph node metastasis (LNM) similar to differentiated cancer. A cohort of 256 patients with early gastric SRC at our center between January 2002 and December 2015 were retrospectively reviewed. Multivariate logistic regression analysis was used to determine the independent factors of LNM. A nomogram for predicting LNM was constructed and internally validated. Additional external validation was performed using the database from Cancer Institute Ariake Hospital in Tokyo (n = 1273)...
