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.

Opisano przypadek klinicznego grzybicze zapalenie rogówki o złożonej etiologii u konia. Chorobę rozpoznano u klaczy, maści gniadej, w wieku 7 lat. Badanie okulistyczne wykazało w dolnym skroniowym kwadrancie rogówki: wrastanie naczyń krwionośnych, naciek zapalny, obrzęk, wieloogniskowe nacieki podnabłonkowe oraz powierzchowne owrzodzenie rogówki z oddzieleniem nabłonka. Cytologia impresyjna oraz badania mikologiczne wykazały w pobranym materiale obecność Aspergillus fumigatus, a także pojedyncze kolonie Aspergillus flavus. Koń był leczony chirurgiczne oraz przy użyciu kropli okulistycznych z 0,2% flukonazolu i 30% DMSO. Doustnie podawano kapsułki flukonazolu, w dawce 500 mg dwa razy dziennie. Po 2 tygodniach od operacji stwierdzono wygojenie się owrzodzenia rogówki, z obecnością białego koloru blizny. Leczenie farmakologiczne kontynuowano przez 12 tygodni. Badanie kontrolne wykonane po 1 roku wykazało znaczne zmniejszenie blizny w porównaniu do stanu po operacji, brak naczyń krwionośnych i w miejscu wrzodu zwiększenie przejrzystości rogówki.

The authors report a clinical case of poliethiological ulcerative mycotic keratitis in horse. The disease was diagnosed with mare, bay colour, aged 7 years. The ocular examination revealed in the inferior cranial quadrant of the right cornea: the superficial and deep blood vessel ingrowth, oedema, multifocal dark brown subepithelial infiltrations as well as superficial corneal ulceration with the demarcated epithelial. The impression cytology and mycological evaluation showed the presence of Aspergillus fumigatus as well as single colonies of Aspergillus flavus in the examined research material. The horse was surgery treated and with the use ophthalmic drops containing 0,2% fluconazole and 30% DMSO mixture. Oral fluconazole 500mg was given twice a day. The ophthalmic examination revealed the complete recovery of the corneal ulceration, with a white scar 2 weeks after operation. The pharmacological treatment was continued by 12 weeks. The control check-up a year after the treatment institution showed no blood vessels growing into the cornea, marked diminishment of the postoperative scar as well as higher corneal transparency at the ulcer site.

During a Cesarean section of a bitch on the 68th day of gestation multiple cauliflower structures in the uteral wall and perforation of the uterus were diagnosed. Two immature dead foetuses were found in the body cavity outside of the uterus. One foetus was joined to the placenta by means of an umbilical cord. Gross pathology and microscopic analysis of histological slices of the uterus wall enabled to diagnose pathological lesions in the dog as a mole (mola hydatidosa destruens).

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.

The aim of this study was to determine the vascularisation level in malignant tumours of the oral cavity. The studied material comprised 10 samples of neoplastic tissue extracted from dogs with a suspicion of oral cavity carcinoma. The samples were collected from nine male and one female dogs of various breeds, aged between 6 and 16 years. The tumours were located within the areas of mandibular and maxillary gingiva. Tumour specimens were preserved in 10% buffered formalin for 24 h, embedded in paraffin, and then sections stained with haematoxylin and eosin were prepared. Tumour type was diagnosed according to the official WHO classification. In order to render the vascular endothelium visible, immunohistochemical staining was performed with the use of the polyclonal antibody against von Willebrand factor F VIII and DAKO EnVision system. In the quantitative analysis of the blood vessels displaying the FVIII factor expansion, a system of computer-assisted microscopic analysis was utilised. In ten microscopic fields the vessels were counted and a mean value per 1 mm² was calculated. The largest numbers of blood vessels were observed in squamous cell carcinomas. In the remaining tumours, the vessel count fluctuated between 78-97/mm² (mean 87). The conducted research indicated that angiogenesis in malignant tumours of the oral cavity has potential diagnostic application in determining the malignancy levels of neoplasms.
