Cytological Diagnosis of Canine tumor
Abstract: Fine-needle aspiration is of great significance in the cytopathological diagnosis of canine tumors. In the study, several clinical cases of common lumps were collected, which aspirated by 5mL syringes or needles and being smeared, dried, fixed, dyed with Giemsa. Through the microscopic examination of these smears, to observe the size and shape of cells, the characteristics of cytoplasm and nucleus, which helps to make pathological diagnosis of the lumps. The results of needle aspiration pathology and other diagnosis techniques shows: 1 case is non-tumorous, which is an axillary abscess. The smear shows abundant neutrophils. 1 case is a benign tumor, the smear of which shows spindle cells in uniform size, diagnosed with fibroma. 3 cases are malignant tumors, respectively, 1 case of which is an osteosarcoma, and the smear shows anisocytosis, anisokaryosis and moderate variable nucleartoplasmic ratio; 1 case of which is a skin squamous cell carcinoma, the smear of which shows clusters or sheets of cells and round to oval nucleis. The histopathological result shows keratinized cancerous pearls in the center of the lesion, karyokinesis in carcinoma cell clusters and infiltration with peripheral lymphocytes and plasma cells; 1 case of which is a testicular cell tumor, and the smear shows round cells inpidually or in small clusters , which have moderate to high N/C ratio, basophilic cytoplasmic and moderate to obvious vacuoles, and the nucleus contains subtle spotted chromatin. In this study, the fine-needle aspiration technique is applied to diagnose clinical cases of lumps, which provide significant reference for the clinical diagnosis, treatment and prognosis of tumors.
