The aims of the study were as follows: a) presentation of the clinical course of primary lung neoplasms in cats and relevant radiographic and autopsy findings, b) comparison of radiographic findings with autopsy results and the course of pathologic process, as well as tracing the mechanism of the tumour development responsible for the character and intensity of clinical symptoms. The study was performed on 2 older (11 and 14 years), neutered female cats, which were euthanized because of severe respiratory distress. The autopsy and histopathological examination of the tissue samples were performed. On the basis of the microscopic examination of tissue specimens two cases of undifferentiated bronchioloalveolar carcinomas were diagnosed. The initial diagnosis of primary lung tumours was based on radiographic findings, although RTG picture was different in each case. Clinical course and laboratory data were unspecific, however leukocytosis with granulocytosis and an increase in erythrocytes were observed in both cases. Despite the same histological type of the tumour in both cases, the clinical courses of disease were different because of different spread routes of the neoplastic process (hematogenic route vs. infiltration of surrounding tissues)
Physical and functional abnormalities of the lids or adnexal ocular structures may result in abnormalities of the cornea and subsequently vision. Cancer begins when normal cells start to change and grow uncontrollably, forming a mass called a tumor. Eyelid tumors can be either benign or malignant. The most common malignant eyelid tumors include basal cell carcinoma, sebaceous gland carcinoma, squamous cell carcinoma and malignant melanoma. Cytologic examination of the fine needle aspiration and biopsy samples may reveal a specific type of neoplasm. All cancers from the eyelid and eye globe need to be removed. Histologic examinations of incised masses are recommended.
Ocular melanoma and melanocytoma are the most common tumors that occurs in dogs and cats. Ocular melanomas are known to be malignant in cats, but melanomas are mostly benign in dogs and have a low incidence of metastasis. In dogs melanomas are locally invasive, and the prognosis is poor when they spread to destroy the eyeball. Some important tumors are: limbal melanocytoma, uveal melanocytoma and diffuse iris melanomas in the cats. These tumors can cause glaucoma or uveitis of the eyeball. Therefore, early diagnosis is important for achieving a good prognosis for dogs and cats with ocular melanoma.
