BACKGROUND: Colorectal cancer (CRC) has been known to complicate Crohn's disease (CD). Several reports in Western population revealed that CRC in CD were characterized by much younger onset and equal distribution of tumors along the entire colon. However, clinicopathologic features of CD-associated CRC in Korean population have not been well documented yet. METHODS: Among 2968 Korean CD patients, 16 patients (0.54%) were found to develop CRC during follow up. We reviewed clinicopathologic features of the 16 CRC patients...

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)...

Signet ring carcinoma (SRCC) of gallbladder is an extremely rare tumor accounting for approximately 3% of all gallbladder carcinomas, with a handful of case reports in the literature. We report a case of signet ring cell carcinoma of the gallbladder in a 70 year-old female who was operated upon after the preoperative diagnosis of cholecystitis with cholelithiasis, based on ultrasonographic findings and subsequently diagnosed as signet ring cell carcinoma of the gallbladder on histopathological examination. Grossly there was no discrete growth, instead tumor presented as linitis plastica like diffuse thickening of the gallbladder wall...

Signet-ring cell ependymoma is a rare variant of ependymoma with only seven cases described in literature. Biological behavior and prognosis of this entity are not well-known until now. We present a case of a 49-year-old female with a history of headache and gait instability. Magnetic resonance imaging showed an upper cervical tumor with cystic component and mural nodule. The patient underwent surgery. Microscopically some cells displayed an eccentric nucleus compressed to the periphery by vacuolated cytoplasm...

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...

Signet ring cell lymphomas are the proliferations of malignant lymphoid cells containing cytoplasmic vacuoles or globules which displace the nuclei, imparting it a signet ring appearance. This rare tumor is a variant of non-Hodgkin lymphoma. Signet ring appearance is due to cytoplasmic accumulation of immunoglobulin or vacuoles derived from multivesicular bodies. These cells, particularly with cytoplasmic vacuoles, may be mistaken for adenocarcinoma cells. We are presenting one such case where immunofluorescence helped us to demonstrate the immunoglobulins on fine needle aspiration smears...

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...

A 65-year-old female presented with an elevated lesion that was identified in the gallbladder fundus via abdominal ultrasound during a medical checkup. The tumor was a pedunculated lesion, measuring 30mm in diameter, that exhibited a blood flow pattern with gradual dense staining throughout the equilibrium phase on the abdominal contrast computed tomography and a high signal intensity on T2-weighted magnetic resonance imaging. Histopathological findings revealed the proliferation of poorly differentiated adenocarcinoma, including signet ring cells, throughout the tumor along with the formation of a mucous lake...

A 90-year-old woman was referred to our hospital because of abdominal distension and pretibial edema. No tumors were palpable in either breast. Her abdomen was distended and palpitation was noticed. Laboratory examination revealed hypercalcemia and elevated levels of tumor markers(PIVKA- II , CEA, CA19-9, SCC). Contrast-enhanced computed tomography(CT) showed pleural effusion and ascites, an approximately 17-mm high-contrast mass in the D area of the left breast, and osteolysis of the dorsal lumber spine. We initiated treatment for pleural effusion, ascites, and hypercalcemia...

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...

An 82-year-old woman with common bile duct (CBD) dilatation observed during routine ultrasonography was referred to our hospital. Preliminary blood tests revealed elevated levels of hepatobiliary enzymes. Computed tomography (CT) scan showed lower bile duct wall thickening and enhancement. Esophagogastroduodenoscopy revealed mildly swollen papilla of Vater, without ulceration. Endoscopic retrograde cholangiography demonstrated that the CBD was grossly dilated with a constriction in the lower part. The final diagnosis indicated poorly differentiated adenocarcinoma of duodenal papilla with signet-ring cells; pT3N0M0, stage IIA (Unio Internationalis Contra Cancrum, 7th edition), for which subtotal stomach-preserving pancreaticoduodenectomy (SSPPD) was performed...

The stress response is a complex mechanism, which includes changes in the immune system to enable organisms to maintain homeostasis. The neurohormones dopamine, noradrenaline (NA) and adrenalin are responsible for the physiological modulations that occur during acute stress. In the present study, we analyzed the effects of NA on the immune system specific to nitric-oxide (NO) production by subpopulations of immune cells (hemocytes) of the ascidian Phallusia nigra. We also investigated the capability of immune cells to produce catecholamine (CA)...

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...

Signet ring cell prostatic intraepithelial neoplasia is a rare speculated variant of high-grade prostatic intraepithelial neoplasia (HGPIN). Here, we present a free-standing and isolated signet ring cell HGPIN that was not associated with invasive carcinoma on needle biopsy and demonstrated the existence of this type of HGPIN variant. The differentiation between HGPIN and intraductal carcinoma of prostate is also discussed.

Untreated bladder exstrophy in an adult is rare, as the defect is obvious and primary reconstruction is usually done in infancy. There are less than 90 reported cases of primary adenocarcinoma in an untreated bladder exstrophy in literature and only two such case reports from India. Of these, only one case was of signet-ring cell type of mucinous adenocarcinoma. Here we report the second case of signet-ring cell adenocarcinoma in a 63 year old male with untreated bladder exstrophy (oldest patient in literature), to highlight the extreme rarity, yet distinct possibility and challenges faced in surgical management of such cases...

CONTEXT: Signet-ring cell lymphoma (SRCL) is a rare morphologic variant of non-Hodgkin lymphoma. Although it was initially reported as a rare morphologic variant of follicular lymphoma (FL), SRCL has to date been described in most types of non-Hodgkin lymphoma, mostly as single-case reports. OBJECTIVE: To study SRCL systematically by immunohistochemical stains and fluorescent in situ hybridization analyses. DESIGN: Seven SRCL cases were stained for CD3, CD5, CD20, PAX-5, CD10, CD21, CD23, cyclin D1, BCL2, BCL6, Ki-67, and MUM-1, and were analyzed by fluorescent in situ hybridization for BCL2, BCL6, MYC, and MALT1 rearrangements...

Introduction. Frequent colonoscopy screenings are critical for early diagnosis of colon cancer in patients with acromegaly. Case Presentations. We performed a retrospective analysis of the incidental diagnoses of colon cancer from the ACCESS trial (ClinicalTrials.gov identifier: NCT01995734). Colon cancer was identified in 2 patients (4.5%). Case  1 patient was a 36-year-old male with acromegaly who underwent transsphenoidal surgery to remove the pituitary adenoma. After surgery, the patient underwent routine colonoscopy screening, which revealed a 40 mm tubular adenoma in the descending colon...

REVIEW
Carlos A Rubio
Colorectal cancer (CRC) is one of the more intensively studied human malignancies. For many years, the general view has been that the vast majority of CRCs in humans evolve from conventional (tubular or villous) adenomas via the adenoma-carcinoma pathway. More recently, serrated colorectal polyps (hyperplastic polyps, sessile serrated polyps and traditional serrated adenomas) have emerged as an alternative pathway of colorectal carcinogenesis in humans. Archival sections from early experiments in Sprague-Dawley (SD) rats injected with dimethylhydrazine (DMH) were reviewed and the histology of colonic neoplasias was re-evaluated...
