Introduction
Spirocerca lupi (S. lupi) is a nematode infecting carnivores in tropical and subtropical areas. Larvae migration trough gastric arteries and thoracic aorta
wall ends at caudal esophagus, where the worms settle, form granulomatous nodules and reach maturity. However, several aberrant migration sites were documented. This is the  rst publication of extradural spinal canal spirocercosis of a dog in Hungary.
Objectives
The aim is to present a case of aberrant S. lupi migration in spinal canal of a dog.
Methods
A 3-year-old, spayed female mixed breed dog was presented to the University of Veterinary Medicine Budapest Teaching Hospital with paraparesis, decreased proprioception. Radiography, computed tomography and myelography were carried out, showing several calci cated discs and an extradural compression at Th10-11 region. A diagnosis of discus hernia was made. During right-side hemilaminectomy of Th9-10 region, a 5 cm long S. lupi adult male was found next to a tumorous mass in the epidural area. Due to poor prognosis, euthanasia was carried out. Gross pathology revealed two more adult worms in the epidural area of Th8-11 vertebrae, and two granulomatous nodules in the caudal esophagus, with 4 more adult female S. lupi worms inside. The tumor was proved to be malignant peripheral nerve sheath tumor, possibly caused by aberrant migration of worms.
Results
This is the  rst documented case of aberrant spinal canal migration of S. lupi in Hungary. The migration can cause tumorformation, which possibly happened here also.
Conclusions
Spirocercosis can be fatal in case of associated tumorformation, either in typical or atypical locations of migration.

Introduction
Combined hepatocellular and cholangiocellular carcinoma (Combined HCC-CC) is a tumor with hepatocellular carcinoma (HCC) and cholangiocellular carcinoma (CC) in same neoplastic tissue. This primary liver tumor is quite rare in dogs.
Objectives
The aim of the case is histopathological investigation of Combined HCC-CC and its metastasis.
Methods
A fourteen years old Husky male dog was brought for necropsy after being euthanized due to general condition disorders like weakness, lethargy and anorexia. After necropsy was performed, tissues were processed routinely and stained with haematoxylin-eosin.
Results
Macroscopically, focal irregular areas in varying sizes with pale white color drew attention especially in
the margins of all hepatic lobes. Masses with similar characteristics were also found in lobes of lungs, right kidney and epicardium of heart. Microscopically, both cuboidal intrahepatic bile duct cells and poligonal hepotocytes drew attention in same areas. All cells showed pleomorphism. The tumor was diagnosed as Combined HCC-CC. Also, cirrhosis and necrosis were seen remarkably in the liver. The neoplastic cells with similar characteristics were also found in lungs, kidney and heart. Neoplastic cells in the lungs and kidney had invasive character. But in the heart, neoplastic cells were limited to vessel lumens and muscle bundles. Degenerative, necrotic and in ammatory changes were also prominent in these organs.
Conclusions
Combined HCC-CC is an uncommon tumor. Also, kidney and heart metastases are rarely reported in HCC and CC tumors. At the same time, the appearance of cirrhosis in liver and necrosis in metastatic organs were remarkable for clinical pathology.
