L. RASMUSSEN, K. VANDERPERREN, E. PAULUSSEN, G. VAN LOON, J. H. SAUNDERS, E. RAES
Abstract: 
To the authors’ knowledge, this is the first report, in which a simultaneous occurrence ofSalmonella-associated multifocal osteomyelitis and intra-abdominal abscessation in a foalpresenting with weight loss, diarrhea and fever is described. No evidence of failure of passiveimmune transfer had been present at birth. Radiographic examination revealed multifocal type Posteomyelitis. Bacterial culture of synovial fluid revealed a Salmonella spp. Antibiotic treatmentwas adjusted based on the sensitivity results; however without clinical improvement. The foaldeveloped abscess formations within the left femoral region, and finally a Salter Harris type Ifracture of the left femur. Euthanasia was elected based on this finding. Post-mortem computedtomography revealed a large mass within the caudal abdomen that extended into the left pelvicand hind limb region, as well as multifocal osteomyelitis.Pathological examination identified the mass as a large abscess with multiple fistula tracts.Salmonella spp. was additionally cultured post mortem.

Author(s): 
L. SONCK, M. HASPENSLAGH, R. DUCATELLE
Abstract: 
Melanocytic tumors are commonly encountered neoplasms in horses. In this case report, an atypicalcase of a melanocytoma in an almost five-year-old Andalusian horse is described. Histopathologicalexamination showed a striking epidermal component consisting of multifocal to miliary nests ofepitheloid cells, which were spread discontinuously in all layers of the epidermis, including the outerroot sheath of the hair follicles. This phenomenon is called pagetoid spreading or buckshot pattern andis a feature of multiple human neoplasms, among which are melanomas, Paget disease and Bowen’sdisease. To the authors’ knowledge, this is the first case report to describe pagetoid spreading in anequine melanocytic tumor.

Abstract: 
A fourteen-year-old Persian cat was referred because of poorly controlled diabetes mellitusdespite insulin and dietary treatment. Clinical signs were severe polydipsia/polyuria (pupd),poor hair coat quality, stomatitis and hind limb weakness. At the time of initial presentation, hewas treated with glargine insulin (0,75 IU/kg BID). A low dose dexamethasone suppression test(LDDST) revealed hypercortisolism (HC). The cat was additionally treated with trilostane, andremission of diabetes mellitus was obtained one year later.This case illustrates the importance of diagnosing an underlying cause of poorly controlleddiabetes mellitus. Although hypercortisolism is rare in cats, it is important to consider the diseasein these cases. The hypercortisolism in this cat was efficiently managed with trilostane, resultingin a good quality of life.

Title: 
Diagnosis and treatment of lumbosacral vertebral instability caused by discospondylitis in a dog
Author(s): 
E. ROYAUX, S. GUILHERME
Abstract: 
A ten-month-old, female canine crossbreed of 40 kg was referred for episodes of severepain non-responsive to analgesics. Neurological examination revealed pain on palpation of thelumbosacral region and non-weight bearing pelvic limb lameness, which was attributed to pain.Discospondylitis at L7-S1 was diagnosed based on radiographs and magnetic resonance imaging.Blood and urine culture were positive for Staphylococcus spp.. Despite ten days of conservativetreatment, the dog did not show any improvement. Dynamic radiographs revealed a vertebralsubluxation of L7-S1 in flexion. Surgery consisting of a dorsal laminectomy and stabilizationof L7-S1 was performed. This resulted in a fast and complete recovery. Follow-up radiographsat six and twelve months after diagnosis showed severe osteolytic changes affecting L7. Despitethese findings, the dog remained clinically normal.

Title: 
Mycobacterial conjunctival granuloma in a Scaly-sided merganser (Mergus squamatus)
Author(s): 
B. GEBOERS, A. GARMYN, T. HELLEBUYCK, R. HAESENDONCK, L. BOSSELER, R. DUCATELLE, G. ANTONISSEN
Abstract: 
A five-year-old, female scaly-sided merganser was presented with a chronic recurrent conjunctivitisof the left eye. Physical examination showed a caseous nodular lesion at the palpebral conjunctiva associatedwith excessive tearing. Necropsy revealed caseous necrotic debris at the left conjunctiva andinfra-orbital sinus, but also multiple granuloma in several internal organs. Histological examinationshowed granulomatous splenitis, hepatitis, arteritis, fibrinonecrotic enteritis and conjunctivitis, andalso amyloidosis of liver and spleen. Bacterial and molecular tests of a conjunctival swab in the liveanimal showed the presence of a multiresistant Escherichia coli strain and Chlamydia psittaci, respectively.These bacteria had only a secondary pathogenic role. No premortem cytological examinationor Ziehl-Neelsen (ZN) staining of the histological section of the conjunctiva biopt or additional tests,such as blood test and radiographs, were performed. Finally, a Mycobacterium avium infection of theconjunctiva and internal organs was confirmed following necropsy by ZN staining and PCR analysis.Local and systemic antimicrobial treatments with fluoroquinolones, tetracyclines and aminoglycosideswere unsuccessful.

Title: 
Microsporum gypseum infection in a horse with severe sweet itch
Author(s): 
F. BOYEN, P. VAN ROOIJ, L. VANSTALLEN, B. FLAHOU, F. HAESEBROUCK
Abstract: 
In a horse with severe sweet itch and a history of corticosteroid treatment for this disorder,a single, well-circumscribed and crusty white lesion was present on the thigh. The geophilicdermatophyte species M. gypseum was cultured from the lesion. The lesion was treated topicallyonce a week with an enilconazole emulsion for four weeks. Full recovery was noted after twomonths. This case suggests that sweet itch combined with systemic corticosteroid treatment, mayact as predisposing factor for dermatophyte infection. In addition, the importance of correctisolation and identification of the causal agent is highlighted.

Abstract: 
In this report, a dog is described that was referred to the Small Animal Department, Faculty of Veterinary Medicine (Ghent University) for further work-up and treatment of a solitary renal cyst. The cyst was treated successfully with ultrasound-guided drainage and percutaneous sclerotherapy. The dog was followed-up during twenty-four months post procedure with renal sonography. The complaints of intermittent lethargy disappeared after the first treatment. The ultrasonographic appearance of the cyst evolved from a round, anechoic, sharply demarcated lesion to an ill-defined, hyperechoic lesion.

Title: 
Peripheral osteoma of the mandible in a cat
Author(s): 
J. VAN DUIJL, J.N. WINER, H. DE ROOSTER, B. ARZI
Abstract: 
A six-year-old, male, castrated domestic shorthair cat was presented for evaluation of an oralmass. Full physical examination revealed a large hard mass arising from the lateral aspect ofthe caudal part of the left mandible. Abdominal ultrasound and thoracic computed tomography(CT) were performed to rule out metastatic disease. In addition, CT of the skull with intravenouscontrast agent was performed. Histopathological examination of extra-oral biopsies confirmedthe tentative diagnosis of peripheral osteoma. A three-dimensional printed skull was used inconjunction with the CT images to determine the detailed location and extent of the mass andto identify anatomical spatial relationships with important neurovascular structures. Surgicaldebulking of the osteoma was performed. The cat recovered uneventfully but the mass regrewnine months after debulking therapy, sooner than expected. Nevertheless, CT scan of the skullwas suggestive for regrowth of the peripheral osteoma rather than for malignant transformation.The owners did not elect to pursue caudal mandibulectomy.

Title: 
Intratumoral chemotherapy in an integumentary squamous cell carcinoma in a cockatiel (Nymphicus hollandicus)
Author(s): 
N. VAN HECKE, A. MARTEL, A. GARMYN, I. VAN DE MAELE, T. HELLEBUYCK, S. CROUBELS, R. DUCATELLE, G. ANTONISSEN
Abstract: 
An eight-year-old, female cockatiel (Nymphicus hollandicus) was presented with anorexia,lethargy, a mass at the lower side of the wing and discoloration of the feathers. Physical examinationshowed an ulcerated nodular integumentary lesion of approximately 4 cm³ ventromedial on thewing at the side of the propatagium and the humerus. Lateral and ventrodorsal radiographsrevealed only hepatomegaly. After a stabilization period, surgical excision of the tumor wasperformed. Based on histopathological evaluation and bacterial culture of the surgically removedtissue, the lesion was typed as an integumentary squamous cell carcinoma with secondarybacterial infection (Corynebacterium sp). Four weeks postoperative, the tumor had recurred.Chemotherapeutic treatment was started with intratumoral carboplatin (1.5 mg/cm³) once aweek. Because of further tumor growth after the second administration of carboplatin, resectionof the mass was performed before the next infiltration. However, the bird died during anesthesia.Despite increase in tumor size, histopathological and immunohistochemical evaluations showeddegeneration of the tumor with intercellular edema and vacuolization of the tumor cells,presumably resulting from carboplatin administration. More research is needed to investigatethe efficacy and safety of the intratumoral administration of carboplatin as a treatment option inbirds with integumentary squamous cell carcinoma.

M.L. GO, N. VALLARINO, N. DEVRIENDT, B. VAN GOETHEM, I. POLIS, E. STOCK, H. DE ROOSTER
Abstract: 
A four-year-old male castrated German shepherd dog was presented with severe left frontleg lameness due to a fibrosarcoma lateral to the elbow. The ill-defined mass was not amendableto wide local excision and a curative-intent limb amputation was performed. Immediately postoperatively,closed incision management with negative pressure wound therapy (NPWT) wasapplied to minimize the risk of postoperative complications. The incision line was covered witha PrevenaTM dressing attached to a NPWT pump set at a continuous negative pressure of -125mmHg. The dressing was removed 72 hours later. No wound complications were evident andfurther healing was unremarkable.
