The current paper presents some cytomorphological aspects in different lesions of the bitch genitalia system, together with their significance for diagnosis. The study was conducted between April 2016 and April 2017 (one year) on 24 bitches with genital lesions. Of the 24 studied cases, six (25%) exclusively exhibited ovarian lesions, four (16.7%) only uterine lesions, four (16.7%) vaginal lesions, while in 10 cases (41.6%) both ovarian and uterine lesions were diagnosed. The sampling for the vaginal lesions was performed both preoperative, through fine needle aspiration(FNA) and impression, and postoperative through abrasive cytology. The uterine and ovarian lesions were sampled after the ovariohysterectomy, through exfoliative and abrasive cytology. The smears were Romanowsky stained and microscopically examined with an immersion objective. The ovarian lesions were tumoral (n=3) and cystic (n=3), the uterine lesions were represented by cystic endometrial hyperplasia-pyometra complex, the vaginal lesions were tumoral - two fibromas and two transmissible venereal tumors (TVT), and the bitches that exhibited both ovarian and uterine pathologies, the uterine lesions were represented by cystic endometrial hyperplasia (CEH)-pyometra complex and the ovarian were represented by cystic ovariopathy (n=8) and tumors (n=2).The cytological examination was of maximum relevance for the tumoral lesions. For the cystic pathology it made the difference between degenerative lesions and cystic tumors. In CEH-pyometra complex, the cytological aspects were very diverse, in correlation with the evolutionary phase of the pathological process and the reactivity of the organism.
