Introduction: Platynosomum fastosum is a dicrocoeliid fluke that infects birds and mammals, especially wild and domestic cats. Case report: A middle-aged male domestic cat was euthanized and examined. Its clinical features had included apathy, emaciation, hepatomegaly and mild jaundice on the mucosae. At necropsy, we noticed enlarged liver and dilated gallbladder. After opening the gallbladder lengthwise, multiple whitish flattened ellipsoidal structures were observed and identified as P. fastosum. The larger parasites were found in gallbladder, with significant different size from cystic duct and intrahepatic biliary ducts (p<0.05). Histopathological analysis revealed fluke-induced suppurative cholecystitis and chronic cholangitis. Precursor lesions of cholangiocarcinoma were reported. Conclusion: This report was part of the first prevalence survey of P.fastosum in municipality of Maracanaú, state of Ceará, northeastern Brazil.

The process of caudal regeneration in lizards does not always occur perfectly, which can cause some abnormalities, such as the appearance of warped or supernumerary tails. Here we report the first cases of tail bifurcation in the Dwarf Gecko, Lygodactylus klugei, and observations about the caudal adhesive pads in individuals with bifurcated tails. Our observations represent a new case of caudal bifurcation for lizard species that have tails with functional specializations and elaborate morphological structures and are the first records of this type of anomaly for the genus Lygodactylus.
