The paper discusses a case of an unusually located eyelid dermoid diagnosed in a 4-month-old, female Cane Corso dog. The observed dermoid was black and brown, located in the eyelid conjunctiva of the left lower lid, covered with keratinising epithelium, and only visible once the eyelid was pulled back. The altered conjunctival surface displayed short, thin hairs. At the 1/3 of the central and side conjunctival border, two hairs were found which suggested additional eyelash growth – on examination, the black hair proved to be a distichiasis, while the other, beige, was a hair growing out of the dermoid. The eyelid border over the evaginated area was thinner, which could only be determined once the eyelid was pulled back. The dermoid was surgically removed along with a fragment of the eyelid. Histopathological examinations revealed the presence of regular skin structures. The surface layer comprised stratified epithelium indicative of slight hyperkeratosis. The dermis displayed numerous follicles in various stages of development, accompanied by sebaceous and sweat glands. On the basis of the location and histopathological analysis, the lesion was classified as a dermoid.
This is a study of 18 cases of canine calcinosis circumscripta (CC). The objective of the research was to present the CC cases recognized in ten years in veterinary clinics in Lublin. The following factors were analyzed: dog age, breed and sex, the anatomical location of calcium salt deposits in each dog, a potential cause of the disorder and the incidence of its remission after surgical treatment. The age of the dogs in the study varied from 6 months to 1 year (11 cases). Seven dogs were more than 2 years old. The dogs belonged to different breeds of both sexes, German Shepherd Dog prevailed (10 cases). The lesions occurred within limb joints (16 cases) and the ventral area of the tongue (2 cases). General clinic signs such as elevated body temperature and apathy were presented in one animal. In five cases local inflammation was observed. In three cases where tissue damage appeared in the affected region there occurred slight bleeding and exudates. None of the dogs had similar symptoms in the case history and none of them had surgical procedures performed in the affected region earlier. Only in one dog calcinosis circumscripta was not the only disease which occurred in that animal. In three cases lesions in the limb region occurred due to apparent physical damages. In the other cases no single cause was established. In eight cases radiographic evaluation was performed. In twelve cases the diagnosis relied on the histopathological examination of the surgically excised lesion; in one case fine needle aspiration cytology was employed. After surgery the recurrence of the disease was reported in three cases.
Type C and type A of C. perfringens were detected in the seat of natural infections in silver foxes characterized by symptoms of haemorrhagic enterotoxemia. In all of the dead foxes characteristic changes were noted in the small intestine and parenchymatous organs. The production of alpha and beta toxins by isolated bacteria was confirmed by the bioassay using white mice and by PCR. The results of the drug sensitivity testing showed that isolated strains were highly susceptible to amoxicillin with clavulanic acid, metronidazole, doxycycline and penicillin with streptomycin.
The occurrence of intestinal tumors is relatively seldom. The article describes a case of a dog’s ileal neoplasia. Symptoms like persistent diarrheas, significant body loss and reduced mobility occurred. Radiography of the abdomen revealed a tumor of 10 cm in diameter located in the left subcostal area. Blood results showed leukocytosis and an elevated activity of alkaline phosphatase. The tumor was removed during laparotomy, and a part of the jejunum was resected. Histopathology showed the presence of T-cell lymphosarcoma. The patient’s health deterioration came 4 months after the surgery. Repeated radiography and ultrasonography revealed secondary cancers in different organs. The dog was euthanased. Necropsy confirmed metastases in intestines, lungs, liver, and kidneys. Therapeutic procedures on malicious tumors of alimentary tract, including this case of ileal lymphosarcoma, are described.
This study reports the case of a 4-year-old female Mastiff dog in which a congenital urachal diverticulum was diagnosed. The disorder was related with atypical clinical manifestations. The animal was referred for a radiological evaluation with the clinical signs of ataxia. The owner stated that the symptoms improved after each spontaneous micturition of a dog. The radiological study revealed the presence of degenerative changes in the lumbosacral spine. Moreover, an abnormal shape of the urinary bladder in the abdominal cavity was observed. The ultrasound imaging showed a large diverticulum in the cranioventral part of bladder. The operative procedure and histopathological analyses have confirmed the presence of a urachal diverticulum. The clinical symptoms completely abated after the surgery.
The authors report a clinical case of poliethiological ulcerative mycotic keratitis in a horse. The disease was diagnosed in a 7-year-old mare, bay colour. In the inferior cranial quadrant of the right cornea ophthalmic examination revealed superficial and deep blood vessel ingrowth, oedema, multifocal dark brown subepithelial infiltrations as well as superficial corneal ulceration with detached epithelium. The impression cytology and mycological examination showed the presence of Aspergillus fumigatus as well as individual colonies of Aspergillus flavus in the examined research material. The horse was treated surgically and with the use of ophthalmic drops containing 0.2% fluconazole and 30% DMSO mixture. Oral fluconazole 500 mg was administered twice a day. The ophthalmic examination revealed the complete recovery of the corneal ulceration with a white scar 2 weeks after the operation. The pharmacological treatment was continued for 12 weeks. A control check-up a year after the treatment showed no blood vessels growing into the cornea, a marked reduction of the postoperative scar as well as higher corneal transparency at the ulcer site.
