No predictors of survival were identified. No associations between outcome of surgical treatment (survival vs nonsurvival) and preoperative findings, biliary rupture, surgical procedure performed, results of histologic examination of the liver, or development of pancreatitis were found. Cholecystoduodenostomy and cholecystectomy appear to be acceptable treatments for gallbladder mucocele.
The medical and necropsy records of 41 cats diagnosed with nonlymphomatous hepatobiliary (NLHB) masses, including neoplasia and cysts, were reviewed. Overall, benign masses (n = 27) were more common than malignant ones (n = 14). The single most common malignancy was cholangiocellular carcinoma. The median age at diagnosis was significantly lower (P < .01) for cats with malignant rather than benign disease. Clinical signs associated with hepatobiliary neoplasia were usually vague and included lethargy, vomiting, and anorexia, often present for at least 2 weeks before presentation. Benign masses were an incidental finding in significantly more (P < .01) of the cases than were malignant masses. Median values for alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin were significantly higher (P < .05) in cats with malignant versus benign masses. The prognosis for malignant disease was poor, with 86% of the cats dying or being euthanatized during hospitalization. Cats with benign disease that underwent exploratory celiotomy were more likely to recover and warranted a more favorable prognosis than cats with malignant tumors. Factors associated with malignancy included age at presentation, presence of clinical signs at presentation, and specific serum chemistry changes.
Resumen— Describimos un caso de alopecia simétrica bilateral en un hurón hembra esterilizada de 3 años. El cuadro resultó estar asociado con un adenocarcinoma adrenocortical y con concentraciones séricas elevadas de estradiol. Además el animal presentaba eritema figurado en la zona dorsolateral, lumbosacra y en la cola con caracteristicas clinicas e histopatológicas parecidas al eritema annulare centrifugum de la especie humana. El eritema figurado se trató con éxito con un producto comercial que contiene el ácido graso omega‐3/omega‐6. [Scott D. W., Gould, J. W., Cayatte, S. M., Lawrence, H. J., Miller, W. H., Jr. Figurate erythema resembling erythema annulare centrifugum in a ferret with adrenocortical adenocar‐cinoma‐associated alopecia (Eritema figurado parecido a eritema anulare centrifugum en un hurón con alopecia asociada a un adenocarcinoma adrenocortical). Abstract— Bilaterally symmetric alopecia and vulvar enlargement is reported in a 3‐year‐old, spayed female ferret. The condition was ultimately shown to be associated with an adrenocortical adenocarcinoma and elevated serum estradiol concentrations. In addition, the ferret had a figurate erythema over the dorsolateral lumbosacral region and tail that was clinically and histopathologically similar to erythema annulare centrifugum in humans. The figurate erythema was successfully treated with a commercial omega‐3/omega‐6 fatty acid‐containing product.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
