Carcinoma de células escamosas em felino: relato de caso

Abstract

The invasive cutaneous carcinoma of scaly cells is one of the most common feline neoplasis developing in this specie a different biological behavior in relation to the other animals and its most usual location are the “white” areas as the head and ears tips besides commonly come as an incurable ulcer or a prolific red tumor. The etiology of the scaly cells carcinoma is not clear in the whole cases. The continuous exposure of no pigmented skin to the violet radiation increases the risks and the first symptoms of this neoplasis are nasal and ocular secretion, epistaxe, noisy breathing and in the most serious cases apathy and weight loss. A bony invasion is possible to occur culminating in changes such as the nasal corneas and jawbone destruction. They are often locally invasive and delay to accomplish metastasis. The cytological examination of these neoplasis wounds is carried out through the impression technique (imprint) or the fine needle aspiration biopsy being useful in the diagnosis although the excision technique is the most reliable technique for the final diagnosis.
