MORPHOLOGICAL FEATURES OF DOG TRANSMISSIBLE VENEREAL TUMOURS WITH GENITAL AND EXTRAGENITAL LOCALIZATIONS

Abstract

Considering the examined cases, we note that 30% were vaginal and vestibular localizations, 25% were situated in cells (implanted tumoral cells), 15% in lymphnode (metastasis in superficial inguinal lymph- node), 10% in nasal cavities and 5% both in penis and lymph- node metastasis. Cytological and histological aspects are very much alike, no matter were they are located in coetaneous localizations and they need differential diagnose in contraction with canine coetaneous histiocytoma, coetaneous limphotoma and poor differentiated mast cell tumors, with the lymphnode metastasis, with the nasal cavities carcinoma, lymphoma and rhinitis.
