Metastatic gastric adenocarcinoma associated with hypertrophic gastropathy resembling Ménétrier’s disease in an adult Labrador Retriever dog

We describe a case of hypertrophic gastropathy (Ménétrier’s like disease) with metastatic gastric adenocarcinoma in a seven-year-old intact female Labrador Retriever dog. The animal suddenly presented with emesis and died. Gross lesions included a marked diffuse thickening of the gastric mucosa and an ulcerated transmural neoplastic mass in the gastric body. Gastric body and fundus were affected by foveolar hyperplasia with loss of chief and parietal cells replaced by mucous cells and marked dilatation of gastric glands. An area of gastric adenocarcinoma with submucosal lymphatic vessels invasion was also present and metastases were observed in the gastric lymph nodes, small intestine, pancreas, lung and liver. Due to its similarity with other gastric proliferative disorders, including this condition in the list of differentials is a necessary step in the diagnostic investigation of canine gastropathies.

Menetrier's disease. A diagnostic and therapeutic challenge.

We present a rare case of hypertrophic gastropathy associated with protein loss. A 35-year-old man was hospitalized for bowel habit changes, abdominal pain, generalized edema and symptomatic anemia. Pertinent laboratory findings included iron deficiency anemia (Hb 6.7g/dl, ferritin 5 ng/ml) and marked hypoalbuminemia (albumin 2.5 g/dl). Endoscopic biopsy samples of giant gastric folds observed along the greater gastric curvature revealed foveolar hyperplasia and significant parietal cell loss. Endoscopic ultrasonography showed gastric parietal thickening with preserved architecture and normal gastric wall layers. Menetrier disease was diagnosed and the patient treated with cetuximab, a monoclonal antibody that inhibits ligand binding of transforming growth factor alpha (TGFa), preventing gastric mucosa cell proliferation. After twelve months of treatment, the patient referred symptoms improvement, and gastric biopsy levels of the proliferation marker protein Ki-67 had decreased.

Presentamos un caso infrecuente de gastropatía hipertrófica asociada a pérdida de proteínas. Un hombre de 35 años fue hospitalizado por cambios en los hábitos intestinales, dolor abdominal, edema generalizado y anemia sintomática. Los hallazgos de laboratorio pertinentes incluyeron anemia ferropénica (Hb 6.7 g/dl, ferritina 5 ng/ml) e hipoalbuminemia marcada (albúmina 2.5 g/dl). Las muestras de biopsia endoscópica de pliegues gástricos gigantes observados a lo largo de la curvatura mayor gástrica revelaron hiperplasia foveolar y pérdida significativa de células parietales. La ecografía endoscópica mostró engrosamiento parietal gástrico con arquitectura conservada y capas de pared gástrica normales. Se diagnosticó enfermedad de Menetrier y se trató al paciente con cetuximab, un anticuerpo monoclonal que inhibe la unión del ligando del factor de crecimiento transformante alfa (TGFa), evitando la proliferación de células de la mucosa gástrica. Después de doce meses de tratamiento, el paciente refirió mejoría de los síntomas y los niveles de la proteína marcadora de proliferación Ki-67 en biopsia gástrica habían disminuido.

Primary gastric rupture in 20 horses from Midwestern Brazil: case report / Ruptura gástrica primária em 20 equinos no Centro-Oeste do Brasil: relato de caso

An 11-year (2007-2018) survey of epidemiological, clinical and pathological findings of horses with primary gastric rupture (PGR) was conducted. Twenty horses presented PGR, nine (45%) horses were clinically evaluated, eleven (55%) were sent dead, and all animals were necropsied. PGR contributed to a prevalence of 0.31% (9/2,868) of all equid attendances, 1.83% (9/491) of colic cases, and 4.1% (20/487) of all equid necropsies. Highly fermentable feed (n=7), gastric impaction (n=4), and perforating gastric ulcer (n=1) were the main causes of PGR; whilst eight horses presented idiopathic gastric rupture. Clinically evaluated horses were tachycardic, tachypneic, febrile, dehydrated, with increased abdominal tension, abnormal mucous membranes and reduced to absent intestinal borborygmi. Improper dietary management, such as the ingestion of low-quality roughage and highly fermentable feedstuffs were detected as the main factors associated with PGR in Midwestern Brazil. It is important to raise awareness in horse owners about proper feed management to minimize PGR.(AU)

Foi realizado um levantamento de 11 anos (2007-2018) dos achados epidemiológicos, clínicos e patológicos de equinos com ruptura gástrica primária (RGP). Vinte equinos apresentaram RGP, dos quais nove (45%) foram avaliados clinicamente e 11 (55%) foram enviados mortos, sendo todos os animais necropsiados. A RGP contribuiu com prevalência de 0,31% de todos os atendimentos de equídeos (9/2.868), 1,83% (9/491) dos casos de cólica, e 4,1% (20/487) das necropsias em equídeos. Alimentos altamente fermentáveis (n=7), compactação gástrica (n=4) e perfuração de úlcera gástrica (n=1) foram as principais causas de RGP, enquanto oito equinos tiveram ruptura gástrica idiopática. Os equinos avaliados clinicamente apresentaram-se taquicárdicos, taquipneicos, febris, desidratados, com mucosas anormais, aumento da tensão abdominal e motilidade intestinal reduzida. O manejo inadequado da dieta, como a ingestão de forragens de baixa qualidade e alimentos altamente fermentáveis, foi o principal fator de risco associado à RGP no Centro-Oeste do Brasil. É importante aumentar a conscientização dos proprietários de equinos sobre o manejo alimentar adequado para minimizar a RGP.(AU)

Changes in the severity of gastric mucosal inflammation associated with Helicobacter pylori in humans coinfected with intestinal helminths.

BACKGROUND: Though a few studies in animal models suggest that intestinal helminths (IH) favorably affect evolution of gastritis associated with Helicobacter pylori (H. pylori) the studies supporting this concept in humans are only a few and are based on serological data. METHODS: To evaluate the possible influence of IH on the human gastric mucosa, three groups of Venezuelan adults with gastropathy (endoscopically diagnosed) were studied: H. pylori-/IH- (n = 17), H. pylori+/IH- (n = 18), and H. pylori+/IH+ (n = 11). Histological analysis (hematoxylin-eosin) and immunohistochemical staining (peroxidase) for cytokines interleukin-1beta (IL-1ß), tumor necrosis factor alpha (TNF-α), gamma interferon (IFN-γ), and interleukin 4 (IL-4) were undertaken in gastric antral biopsies. RESULTS: Expression of the four cytokines was detected in all individuals in varying degrees, but proinflammatory cytokines were expressed in a higher degree in the H. pylori+/IH- group, mainly IL-1ß (Th1-dominant immune response), associated with a higher degree of both histological inflammation and gastric cancer risk index (GCRI), as compared to the H. pylori-/IH- group. In contrast, an increased expression of IL-4 and a reduced expression of proinflammatory cytokines (Th2-dominant response), plus the tendency to a lower degree of mononuclear infiltration, mucosal atrophy in gastric corpus, and GCRI, were evidenced in the coinfected group. CONCLUSIONS: The findings of the present study is perhaps the first histological evidence of a possible modulatory effect of IH on the gastric mucosal inflammatory response due to H. pylori infection in humans.

The Mexican consensus on the diagnosis, treatment, and prevention of NSAID-induced gastropathy and enteropathy. / Consenso mexicano sobre diagnóstico, prevención y tratamiento de la gastropatía y enteropatía por antiinflamatorios no esteroideos.

More than 30 million persons worldwide take nonsteroidal anti-inflammatory drugs (NSAIDs) on a daily basis, and annual consumption is increasing. In addition to their analgesic and anti-inflammatory properties, NSAIDs also produce well-known gastrointestinal adverse events. There is no consensus in Mexico on the diagnosis, treatment, and prevention of NSAID-induced gastropathy and enteropathy, and so the Asociación Mexicana de Gastroenterología brought together a group of experts to establish useful recommendations for the medical community. Thirty-three recommendations were formulated in the present consensus, highlighting the fact that the risk for NSAID-induced gastrointestinal toxicity varies according to the drug employed and its pharmacokinetics, which should be taken into account at the time of prescription. The risk factors for gastroduodenal complications due to NSAIDs are: a history of peptic ulcer, age above 65 years, high doses of NSAIDs, Helicobacter pylori infection, and the presence of severe comorbidities. The symptoms and gastroduodenal damage induced by NSAIDs vary, ranging from an asymptomatic course to the presentation of iron-deficiency anemia, bleeding, stricture, and perforation. Capsule endoscopy and enteroscopy are direct diagnostic methods in NSAID enteropathy. Regarding prevention, the minimum dose of an NSAID needed to achieve the desired effect, administered for the shortest period of time, is the recommendation. Finally, proton pump inhibitors are the gold standard for the prophylaxis and treatment of gastroduodenal effects, but they are not useful in enteropathy.

Carvedilol as primary prophylaxis for gastric variceal bleeding in portal hypertension model in rats / Carvedilol como profilaxia de sangramento em varizes gástricas em modelo de hipertensão portal em ratos

ABSTRACT Background: Portal hypertension (PH) can be measured indirectly through a hepatic vein pressure gradient greater than 5 mmHg. Cirrhosis is the leading cause for PH and can present as complications ascites, hepatic dysfunction, renal dysfunction, and esophagogastric varices, characterizing gastropathy. Aim: To evaluate the use of carvedilol as primary prophylaxis in the development of collateral circulation in rats submitted to the partial portal vein ligament (PPVL) model. Method: This is a combined qualitative and quantitative experimental study in which 32 Wistar rats were divided into four groups (8 animals in each): group I - cirrhosis + carvedilol (PPVL + C); group II - cirrhosis + vehicle (PPVL); group III - control + carvedilol (SO-sham-operated + C); group IV - control + vehicle (SO-sham-operated). After seven days of the surgical procedure (PPVL or sham), carvedilol (10 mg/kg) or vehicle (1 mL normal saline) were administered to the respective groups daily for seven days. Results: The histological analysis showed no hepatic alteration in any group and a decrease in edema and vasodilatation in the PPVL + C group. The laboratory evaluation of liver function did not show a statistically significant change between the groups. Conclusion: Carvedilol was shown to have a positive effect on gastric varices without significant adverse effects.

RESUMO Racional: A hipertensão portal (HP), medida indiretamente através do gradiente pressórico da veia hepática >5 mmHg, tem como principal causa etiológica a cirrose. Possui como complicações a ascite, disfunção hepática, disfunção renal e varizes esofagogástricas, que caracterizam o quadro de gastropatia. Objetivo: Avaliar o uso do carvedilol como profilaxia primária no desenvolvimento da circulação colateral em ratos submetidos ao modelo de ligadura parcial de veia porta (LPVP). Método: Estudo experimental qualitativo e quantitativo no qual foram utilizados 32 ratos Wistar, divididos em quatro grupos (n=8): grupo I - cirrose + carvedilol (LPVP+C); grupo II - cirrose + veículo (LPVP); grupo III - controle + carvedilol (SO - sham-operated+C); grupo IV - controle + veículo (SO - sham-operated). Após transcorridos sete dias do procedimento cirúrgico, foi administrado carvedilol (10 mg/kg) e veículo (1mL) para os respectivos grupos por sete dias consecutivos. Resultados: A análise histológica não mostrou alteração hepática em nenhum grupo e diminuição de edema e vasodilatação no grupo LPVP+C. A avaliação laboratorial da função hepática não mostrou alteração com significância estatística entre os grupos. Conclusão: Carvedilol mostrou ser fármaco com efeito positivo no sangramento das varizes gástricas e sem efeitos adversos significantes.

Gastropatía hiperplásica de tipo foveolar con Coinfección por Helicobacter pylori / Hyperplastic Gastropathy of the Foveolar Type with Helicobacter Pylori Coinfection

La Gastropatía hiperplásica de tipo foveolar o Enfermedad de Ménétrier es una gastropatía hipertrófica premaligna rara.

Antiulcer and Antioxidant Activity of a Lectin from Mucuna pruriens Seeds on Ethanol- induced Gastropathy: Involvement of Alpha-2 Adrenoceptors and Prostaglandins.

ETHNOPHARMACOLOGICAL RELEVANCE: Mucuna pruriens (Mp) belongs to Leguminosae family, it is native of tropical regions and used to treat several maladies such as urinary, neurological, and menstruation disorders, constipation, edema, fever, tuberculosis, ulcers, diabetes, arthritis, dysentery, and cardiovascular diseases. Mp seeds are rich in bioactive compounds, for instance, lectins, a heterogeneous group of proteins and glycoproteins with a potential role as therapeutic tools for several conditions, including gastric disorders. This study investigated the acute toxicity, gastroprotective, and antioxidant activities of a lectin from Mucuna pruriens seeds (MpLec) on ethanol-induced gastropathy model in mice. MATERIAL AND METHODS: Mice received MpLec (5 or 10 mg/kg; i.v.) and were observed for acute toxicity signs; in another experimental series, mice were pre-treated with MpLec (0.001; 0.01 or 0.1 mg/kg, i.v.), ranitidine (80 mg/kg, p.o.), or saline (0.3 mL/30g, i.v.) before ethanol 99.9% (0.2 mL/animal, p.o.), and euthanized 30 min after ethanol challenge. Macroscopic and microscopic gastric aspects, biochemical parameters (tissue hemoglobin levels, iron-induced lipid peroxidation, GSH content, SOD activity, and gastric mucosal PGE2) were measured. Additionally, pharmacological tools (yohimbine, indomethacin, naloxone, L-NAME) were opportunely used to clarify MpLec gastroprotective mechanisms of action. RESULTS: No toxicity signs nor death were observed at acute toxicity tests. MpLec reduced ethanol-induced gastric damage, edema, and hemorrhagic patches formation, as well as decreased lipid peroxidation, SOD activity, and increased GSH content. Yohimbine and indomethacin prevented MpLec effects, suggesting the involvement of alpha-2 adrenoceptors and prostaglandins in the MpLec-mediated effects. CONCLUSION: MpLec does not present toxicity signs and shows gastroprotective and antioxidant activities via alpha-2 adrenoceptors and prostaglandins in the ethanol-induced gastropathy model.

Ménétrièr disease in a pediatric patient with particular reference to echoendoscopy, endoscopic and anatomopathological presentation and evolutionary and therapeutic aspects / Doença de Ménétrier em paciente pediátrico com destaque para apresentação eco e endoscópica, anatomopatológica e aspectos evolutivos e de conduta

ABSTRACT Ménétrier's disease (MD) is included in the group of hypertrophic gastropathy; is a rare gastric hyperplasia that affects adults and children, with different behavior between these groups. We know that its etiology is related to allergens and co-infections. It's characterized by the hypertrophy of the gastric folds, with the appearance of cerebral convolutions on Upper Gastrointestinal Endoscopy (UGE) and, histologically, by the mucosal hypertrophy at the expense of foveolar hyperplasia and atrophy of the glands in body and fundus of the stomach. The UGE together with the gastric tissue biopsy confirms the diagnosis. What concerns us in the following case, however, is patient's long-lasting evolution, about eight years.

RESUMO Inclui-se a doença de Ménétrier (DM) no grupo das gastropatias hipertóficas, sendo uma hiperplasia gástrica rara que acomete adultos e crianças, com comportamento distinto entre esses grupos. Sabemos que sua etiologia relaciona-se com alérgenos e coinfecções. Caracteriza-se pela hipertrofia das pregas gástricas, com aspecto de circunvoluções cerebrais à endoscopia digestiva alta (EDA) e, histologicamente, pelo alargamento da mucosa às custas de hiperplasia foveolar e hipotrofia das glândulas em corpo e fundo gástrico. A EDA, junto à biópsia gástrica, confirma o diagnóstico. O que nos intriga no caso a seguir é o tempo evolução arrastado da paciente, cerca de oito anos.

Severe hypoproteinemia as a harbinger of Ménétrier's disease in autoimmune pancreatitis / Hipoproteinemia grave como indicador de doença de Ménétrier na pancreatite autoimune

Summary Ménétrier's disease is an extremely rare disease of unknown etiology causing gastric mucosal hypertrophy and protein-losing gastropathy. Rare cases of this condition have been reported in patients with autoimmune diseases. However, to the best of our knowledge, Ménétrier's disease associated with autoimmune pancreatitis (AIP) has never been reported. We described a case of severe hypoproteinemia as a harbinger of Ménétrier's disease associated with AIP. The patient was successfully treated with octreotide and high-protein diet, which led to symptomatic remission and significant improvement in serum levels of albumin and recovery of the nutritional status. Thus, in AIP patients presenting with severe and persistent hypoproteinemia without apparent cause, clinicians need to consider Ménétrier's disease in the differential diagnosis. In this setting, endoscopic evaluation with histological examination of gastric biopsy material, including a full-thickness mucosal biopsy of involved mucosa, may be helpful in promptly establishing the diagnosis and allowing appropriate and timely therapy.

Resumo A doença de Ménétrier é uma condição extremamente rara, de etiologia desconhecida, caracterizada por hipertrofia da mucosa gástrica e gastropatia perdedora de proteína. Casos raros dessa patologia têm sido relatados em pacientes com doenças autoimunes. Até o momento, desconhecemos qualquer relato dessa doença associada à pancreatite autoimune (PAI). Descrevemos um caso de hipoproteinemia grave como indicador de doença de Ménétrier associada à PAI. O paciente foi tratado de forma satisfatória com octreotide e dieta hiperproteica, alcançando remissão sintomática, melhora significativa das concentrações de albumina e recuperação do estado nutricional. Portanto, em pacientes com PAI e hipoproteinemia grave e persistente, deve-se considerar a doença de Ménétrier como um diagnóstico diferencial. Nesses casos, a avaliação endoscópica com biópsia gástrica, incluindo biópsia de toda a espessura da mucosa, pode ser útil no estabelecimento do diagnóstico e do pronto início da terapêutica.

Supervivencia del paciente cirrótico con gastropatía portal hipertensiva / Survival of the Cirrhotic Patient with Hypertensive Portal Gastropathy

Introducción: la gastropatía portal hipertensiva constituye una complicación de la hipertensión portal que ocurre en pacientes cirróticos. Objetivo: determinar la probabilidad de supervivencia en un grupo de pacientes cirróticos con gastropatía portal hipertensiva. Métodos: seguimiento longitudinal, prospectivo, para estudiar la supervivencia de 34 pacientes con cirrosis hepática atendidos en el servicio de Gastroenterología del Hospital Militar Central Dr. Luis Díaz Soto desde octubre de 2012 hasta octubre del 2015. Se construyeron las curvas de sobrevida total y por estratos, según clasificación de Child-Pugh-Turcotte, etiología de la cirrosis, gravedad de la gastropatía y ocurrencia de sangrado agudo durante el período de observación. Se utilizó para ello el método de Kaplan-Meier y la comparación de las curvas por el logaritmo de rangos. Resultados: se apreció una probabilidad de supervivencia global de 94,1 por ciento a los dos meses y 61,7 por ciento a los 30 meses. La media de la supervivencia para pacientes con gastropatía leve y grave fue de 29,1 y 29,7 meses, respectivamente; esta fue de 28,3 meses para casos con cirrosis por virus C y de 30,1 meses para los de otras etiologías. Hubo predominio de casos en estadios de Child A (41,2 percent) y B (47,1 percent), con una media de supervivencia de 33,5 y 30,1 meses; para los del Child C (12 por ciento) fue de 12 meses; (p= 0,05). De los pacientes, el 35,3 por ciento de los casos sangraron, con una media de supervivencia de 25,5 meses inferior respecto a los que no sangraron (p= 0,35). Conclusiones: la presencia de gastropatía portal hipertensiva se relaciona con una mayor probabilidad de fallecer cuando hay un mayor deterioro de la función hepática o ha ocurrido un sangrado agudo, a partir de los 30 meses de haberse realizado su diagnóstico(AU)

Introduction: Hypertensive portal gastropathy is a complication of portal hypertension that occurs in cirrhotic patients. Objective: Determine the probability of survival in a group of cirrhotic patients with hypertensive portal gastropathy. Methods: a longitudinal, prospective follow-up was conducted to study the survival of thirty four (34) patients with liver cirrhosis and they were treated at the Gastroenterology Service of Dr. Luis Díaz Soto Central Military Hospital from October 2012 to October 2015. Full-length and strata survival curves were constructed, according to Child-Pugh-Turcotte classification, as well as etiology of cirrhosis, severity of gastropathy, and occurrence of acute bleeding during the observation period. Kaplan-Meier method was used and the comparison of the curves by the logarithm of ranges. Results: A global survival probability of 94.1 was observed at two months and 61.7 percent at 30 months. The mean survival for patients with mild and severe gastropathy was 29.1 and 29.7 months, respectively; this was 28.3 months for cases with C virus cirrhosis and 30.1 months for those of other etiologies. There were predominant cases in Child A (41.2 percent) and B (47.1 percent), with an average survival of 33.5 and 30.1 months; For Child C (12 percent) was 12 months; (P = 0.05). 35.3 percent of the cases bled, with an average survival of 25.5 months lower than those who did not bleed (p = 0.35). Conclusions: The presence of hypertensive portal gastropathy is associated with a greater probability of dying when there is a greater deterioration of the liver function or acute bleeding has occurred, as of 30 months after having been diagnosed(AU)

Caracterización clínica de pacientes cirróticos con gastropatía portal hipertensiva / Clinical Characterization of Cirrhotic Patients with Hypertensive Portal Gastropathy

Introducción: la gastropatía portal hipertensiva (GPH) constituye una complicación de la hipertensión portal de relevancia clínica, que aparece en pacientes con cirrosis hepática. Objetivo: caracterizar los diferentes tipos de gastropatía portal hipertensiva (GPH) según la presencia de manifestaciones de hipertensión portal, el estado de la función hepática y la ocurrencia de eventos de sangrado digestivo. Método: estudio descriptivo, de corte transversal que incluyó 46 pacientes con diagnóstico de cirrosis y evidencia endoscópica de gastropatía portal hipertensiva (GPH), atendidos entre 2011-2013 en el servicio de Gastroenterología del Hospital Militar Central Dr. Luis Díaz Soto. Se clasificaron según su forma leve o grave y se hicieron comparaciones entre ambos grupos. Resultados: el 78,2 por ciento de los pacientes presentó una gastropatía leve y la localización más frecuente resultó ser el fondo gástrico (78,2 por ciento). Todos los casos con la forma grave fueron hombres (p=0,008). Entre los que tuvieron una gastropatía grave, predominaron los que tuvieron un mayor diámetro de la porta (18,3 mm vs 13,5 mm, p=0,001) y del bazo (137,4mm vs130,03 mm, (p=0,0002), así como los que también tenían várices esofágicas (100 por ciento, p=0,007), por lo que el sangrado agudo también fue más frecuente entre ellos (60 por ciento, p=0,01). No se manifestaron diferencias con los parámetros hematológicos de hipertensión portal ni con los grados de función hepática, aun cuando el 63 por ciento de los pacientes se encontró en los grupos B y C de la clasificación de Child-Pughs-Turcotte. Conclusiones: la forma grave de la gastropatía portal hipertensiva (GPH) es la menos frecuente, pero se acompaña de alteraciones clínicas, humorales e imaginológicas relevantes, que requieren una atención personalizada para este tipo de enfermos(AU)

Introduction: Hypertensive portal gastropathy (HPG) is a complication of portal hypertension of clinical relevance, which appears in patients with liver cirrhosis. Objective: Characterize the different types of hypertensive portal gastropathy (HPG) according to the presence of manifestations of portal hypertension, the state of liver function and the occurrence of digestive bleeding events. Method: A descriptive, cross-sectional study was conducted in 46 patients diagnosed with cirrhosis and endoscopic evidence of portal hypertensive gastropathy (HPG), treated from 2011 to 2013 in the Gastroenterology Department of Dr. Luis Díaz Soto Central Military Hospital. They were classified according to mild or severe form and comparisons were made between both groups. Results: 78.2 percent of the patients presented mild gastropathy and the most frequent location was the gastric fundus (78.2 percent). All cases with the severe form were men (p = 0.008). Among those who had severe gastropathy, those with larger diameter of the portal (18.3 mm vs 13.5 mm, p = 0.001) and spleen (137.4 mm vs 130.03 mm, p = 0, 0002), as well as those who also had esophageal varices (100 percent, p = 0.007), so that acute bleeding was also more frequent among them (60 percent, p = 0.01). Hematologic factors of portal hypertension or with degrees of liver function, although 63 percent of patients were found in groups B and C of the Child-Pughs-Turcotte classification. Conclusions: The severe form of hypertensive portal gastropathy (GPH) is the least frequent, but it is accompanied by relevant clinical, humoral and imaging alterations, which require a personalized attention for this type of patients(AU)

Scirrhous eosinophilic gastritis in two dogs / Gastrite eosinofílica esquirrosa em dois cães

Scirrhous eosinophilic gastritis (SEG) is characterized by diffuse infiltration of eosinophils and concomitant fibrovascular tissue proliferation in the stomach wall. The condition is a rare occurrence with an unknown cause. Two dogs were examined with a history of progressive weight loss, emesis, melena and anorexia. Complete blood cell counts of both cases revealed anemia and eosinophilia, while ultrasonography examination revealed thickening of the stomach wall. Due to suspected gastric neoplasia and a poor clinical prognosis, the dogs were euthanized. At necropsy, both had markedly distended stomachs with a diffusely thickened and firm wall. The spleens of both dogs were enlarged with a nodular surface. Histological evaluation revealed diffuse infiltrate of eosinophils, fibrovascular tissue proliferation and fibrinoid degeneration in blood vessel walls of stomach and spleen. SEG is a rare pathological condition that must be considered as a possible diagnosis in dogs presenting gastrointestinal signs and eosinophilia.(AU)

A gastrite eosinofílica esquirrosa (GEE) é caracterizada por infiltrado inflamatório difuso de eosinófilos e concomitante proliferação de tecido fibrovascular no estômago. A condição apresenta ocorrência rara e causa desconhecida. Dois cães foram examinados com histórico de emagrecimento progressivo, êmese, melena e anorexia. O hemograma de ambos os casos revelou anemia e eosinofilia, enquanto o exame ultrassonográfico evidenciou espessamento da parede do estômago. Diante de suspeita de neoplasia gástrica e devido ao prognóstico desfavorável, foi realizada a eutanásia dos cães. Na necropsia, ambos apresentavam estômago acentuadamente aumentado, com parede difusamente espessada e firme. O baço dos dois cães apresentava-se aumentado e com superfície nodular. O exame histopatológico revelou infiltrado difuso de eosinófilos, proliferação de tecido fibrovascular e degeneração fibrinoide na parede de vasos sanguíneos no estômago e baço. A GEE é uma condição patológica rara que deve ser considerada no diagnóstico em cães que apresentem sinais gastrointestinais e eosinofilia.(AU)
