Evaluation test #19832/2017
QUESTION 1
Clinically, gastric ulcers are characterized by:
Anemia and fecal occult blood.
Hemorrhage typically in the chronic form with mane.
Metrorrhagia.
Rectorragia and melena.
QUESTION 2
The growth-pattern of signet ring cell carcinomas are:
They originate frequently in the serosa and extend towards the light.
They form concentric nests with keratin inside.
This tumor displays an expansive and infiltrative growth, disturbing and replacing normal tissue.
Laces of neoplastic cells surround poor cellular areas, well demarcated and partially encapsulated.
QUESTION 3
Neoplastic cells in the signet ring cell carcinoma:
They have a broad cytoplasm with a large vacuole containing mucopolysaccharides.
They are flattened, with scarce cytoplasm and are arranged concentrically, forming "keratin pearls".
This tumor only is observed in the mucosa, not in deeper layers.
Signet ring cells are a histological finding without diagnostic relevance in dogs.
QUESTION 4
The typical location of ulcers produced by gastric carcinomas is in:
Cardias.
Fundus.
Anthropiloric region.
Lesser curvature of stomach.
QUESTION 5
The presence of ulcers in the stomach during necropsy:
The histopathological study of endoscopic biopsies is not useful since the diagnosis is mainly by imaging techniques.
The presence of a blood clot in the center of the lesion is characteristic of a chronic process.
Differential diagnosis must be made with numerous diseases, including neoplasms and chronic kidney disease.
Discards neoplastic etiology as tumors do not produce an increase level of gastric acidity.
