The cutaneous cancers are among the most frequently diagnosed in veterinary medicine before it is sought that the diagnosis of these tumors are fast and effective. In veterinary medicine the use of cytology as a method for diagnosis has increased. Therefore is necessary that studies demonstrate the technical efficiency so that it can be used as only tool. This study aimed to compare the diagnosis made by cytological and histological techniques. Skin and subcutaneous tumors of dogs and their neoplastic type are more easily diagnosed by cytology and are the most prevalent tumors in this animal spécies, attended by two veterinary hospitals in Campo Grande/MS from March 2012 to December 2013. Tumor cell samples were collected by fine needle aspiration and surgical punch of 91 dogs. The cytological results showed an efficacy of 69.69% in relation to histopathology. For differentiating between neoplastic and non-neoplastic growth, the efficiency increases to 91.91%. In order to differentiate benign from malignant tumors, it was possible to find an agreement in the order of 68.13%. The most prevalent tumors were mastocytoma, followed by lipoma, fibrosarcoma and basal cell tumor. |
