Rak przelyku u psa - ocena endoskopowa i patomorfologiczna

Neoplasms of the esophagus are very rare in dogs. They account for 0.5% of all tumors. In the presented case the development of carcinoma was latent. The first symptoms were hypersalivation, vomiting, the backward flow and difficulty in swallowing of solid food. Subsequently the dog wasn’t able to swallow fluids. Hyperleucocytosis, lymphocytosis, monocytosis, anemia and elevated alkaline phosphatase level in the serum suggested tumor growth. An esophagoscopy was conducted as was oesophagostenosis: a tumor with hemorrhagic focuses, ulcer formations and erosions were observed. The dog was subjected to euthanasia. Specimens for histological examination were taken. The histology and immunohistological analysis confirmed the diagnosis of squamosus cell carcinoma.
