RATIONALE: Choledochal cysts are a risk factor for the development of cholangiocarcinoma. Hence, complete surgical excision is the preferred treatment in most cases. However, cholangiocarcinoma still can develop from the remnant biliary system after surgical excision. Signet-ring cell carcinoma is a rare type of cancer of the biliary system, and the occurrence of signet-ring cell carcinoma after surgical excision of choledochal cysts has not been reported in the English literature to date...

Signet ring cell carcinoma is a rare form of adenocarcinoma that predominantly affects the stomach. Signet ring cell carcinoma originated from the ileum is extremely rare and the prognosis is poor. We present a case of small bowel obstruction with features suggesting Crohn disease of the ileum. The symptoms were chronic diarrhea and abdominal pain with a family history of inflammatory bowel disease. The patient underwent surgery and histopathology revealed both aspects of signet ring cell carcinoma and Crohn disease of the ileum...

BACKGROUND: Gastric signet ring cell carcinoma (SRC) has shown a favorable outcome in early stages but has a worse prognosis than non-SRC in advanced stages. However, the cause for this stage-dependent prognostic impact has not been determined. This study aimed to compare clinicopathologic features and recurrence patterns between gastric SRC and non-SRC in a cohort of Eastern patients. METHODS: This study reviewed the prospectively collected data of 764 patients undergoing curative resection for gastric cancer from 2005 to 2008...

The incidence of Helicobacter pylori-negative gastric cancer is very low. A 60-year-old man was referred to Tokai University Hospital from a local clinic because of eosinophilia. The laboratory data revealed prominent eosinophilia, with a white blood cell count of 7,900/μl and increased eosinophil granulocyte level of 1,659/μl. After an examination for secondary eosinophilia, esophagogastroduodenoscopy showed an enlarged gastric fold in the corpus, suggesting type 4 gastric cancer. Repeated EGD and a re-biopsy demonstrated poorly differentiated adenocarcinoma and signet ring cell carcinoma...

BACKGROUND/AIM: Laser-based photodynamic endoscopic diagnosis (LPDED) is a type of endoscopic diagnosis that uses the fluorescence caused by the photochemical reaction that occurs when a fluorescent substance is irradiated by a light of a specific wavelength. Although 5-aminolevulinic acid (5-ALA) can detect early gastric cancer (EGC) during LPDED, there is an unresolved issue of the differences in fluorescence intensity among histopathological types of gastric cancer. Thus, the aim of the present study was to assess whether protoporphyrinogen oxidase (PPOX), involved in the activation of protoporphyrin IX, can affect the fluorescence intensity in EGC...

Goblet cell carcinoid (GCC) is an uncommon tumor of the vermiform appendix. Due to a broad spectrum of morphological differentiation, subclassification and grading of GCCs remains an area of controversy. Two separate systems have proposed classifying GCC tumors into three (classical GCC; adenocarcinoma ex-GCC, signet ring cell type; adenocarcinoma ex-GCC, poorly differentiated carcinoma type) OR two subgroups (low and high grade GCC) based on morphological criteria. We independently compared the inter-observer variability associated with each classification system...

Pulmonary lymphangitic carcinomatosis (PLC) is defined as infiltration of the lymphatic vessels and perilymphatic connective tissue with tumor cells, which is secondary to malignancy. Therefore, it rarely appears as an initial finding preceding a diagnosis of malignancy. A 30-year-old male patient was hospitalized in our clinic with a pre-diagnosis of interstitial lung disease owing to the complaints of dry cough, progressive dyspnea, and acute respiratory insufficiency. He was diagnosed with signet ring cell carcinoma, which is a histologic subtype of adenocarcinoma, via gastroscopy, and lung involvement was consistent with PLC...

Nearly 70% of gastric cancer recurrences occur as peritoneal dissemination. Most of the treatment for recurrence of gastric cancer dissemination is chemotherapy; depending on the symptoms and the site of recurrence, palliative bypass surgery may be performed. Intensive treatment is often difficult for elderly patients over 85-years-old. This case was a 91-year-old female who underwent total gastrectomy for gastric cancer(signet-ring cell carcinoma)7years prior. Two years ago, a stenosis due to recurrence was revealed in the small intestine and bypass surgery was performed...

We report a 72-year-old woman with rare metastases of gastric cancer to the bone, skin, and ovary occurring more than 8 years after distal gastrectomy, which were subsequently effectively controlled. Histopathological diagnosis revealed signetring cell carcinoma, and the comprehensive findings were pT4a, pN3, ly2, v0, and Stage III c. The adjuvant chemotherapy of S- 1 plus cisplatin(CDDP)was switched to S-1monotherapy for 4 years and then to tegafur/uracil(UFT)for an additional year. Eight years after the operation, I-CTP and alkaline phosphatase(ALP)levels were elevated, and bone scintigraphy revealed bone metastasis...

A 78-year-old man underwent an upper gastrointestinal endoscopy for evaluation of epigastralgia. Endoscopy revealed a bulky type 3 tumor in the lesser curvature of the upper body. A biopsy showed a poorly differentiated adenocarcinoma with signet ring cell carcinoma. Additionally, abdominal computed tomography(CT)showed bulky lymph node metastases leading to a diagnosis of cT3N2M0, Stage III A carcinoma. Following administration of 2 courses of neoadjuvant chemotherapy (NAC)using S-1/cisplatin(CDDP), CT revealed significant regression of the primary lesion and lymph nodes...

RATIONALE: Gastrointestinal carcinoma is rare during pregnancy. It is usually diagnosed at an advanced stage because special gastrointestinal symptoms are generally overlooked during pregnancy, and there are many limitations and contraindications for using diagnostic tools during pregnancy. PATIENT CONCERNS: We present a case of a 29-year-old patient with 27 weeks and 5 days of gestation due to massive ascites and hydrothorax. DIAGNOSES: The patient was diagnosed with an advanced gastrointestinal cancer...

RATIONALE: There is currently no consensus on the ideal method for obtaining deep tissue biopsy material of advanced gastric LP. EUS-FNA has potential as a useful diagnostic method. Thus, we report the case of a 46-year-old male with advanced gastric linitis plastica (LP) who was diagnosed using endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). PATIENT CONCERNS: The patient underwent esophagogastroduodenoscopy (EGD) because of epigastric pain at a local clinic...

Primary signet cell cancer of the urinary bladder is a relatively rare entity. Since there is no mucinous epithelium in the bladder, It is proposed that the tumor arises from metaplastic urothelium. Two thirds of the tumours are mucin secreting, in most of which the site of the deposition is either extracellular or intracellular displacing the nucleus to a peripheral crescent, giving the cells a signet ring appearance. The tumours are most often infiltrative and diffusely involving the majority of the bladder akin to its name sake in stomach...

Signet-ring morphology is recognized throughout the gastrointestinal tract. However, this pattern may be observed in other primary sites giving rise to diagnostic challenges in the work-up of metastases. Relatively newer immunohistochemical markers have not been evaluated in this context. We assessed expression patterns of several common immunohistochemical markers in tumors with signet-ring morphology to delineate a pragmatic approach to this differential diagnosis. Primary breast and gastrointestinal carcinomas showing signet-ring features were reviewed...

INTRODUCTION: The incidence, survival, and propensity for nodal metastasis in early-stage gastric signet ring cell carcinoma have not been defined in the United States. These data are critical determinants for treatment allocation. METHODS: Cases of gastric signet ring cell carcinoma were extracted from the national SEER database for the years 2004-2013. Age-standardized incidence was derived. Survival was calculated using the Kaplan-Meier method. Univariate and multivariate analyses were performed to identify predictors of nodal metastasis...
