Two clinical laboratory diagnostic methods, cytology and histology, were introduced in practice, and the conditions, circumstances and advantages of their application were defined. Samples were obtained by skin biopsy ( n = 35) and cytological sampling techniques ( n = 33) from 41 dogs and four cats with skin disease. Cases were grouped into three categories: allergic dermatitis, fungal and parasitic skin diseases, and other skin diseases (including endocrinopathies, autoimmune, neoplastic, congenital, hereditary and infrequent skin disease). In each category, histological findings were evaluated for their information and their role in achieving the clinical diagnosis. We grouped the results of the histological examination into three groups: (1) essential to make the diagnosis and gave the final diagnosis; (2) not essential, but was a confirmation, and gave only the causal category; and (3) only a histological diagnosis without causal category. Results proved that histological diagnoses alone helped significantly in reducing the numbers of differential diagnoses in fungal and parasitic, and other skin diseases. The histological diagnoses were significantly more important in determining the final diagnosis in cases of other skin diseases compared to the allergic dermatitis ( P < 0.001) and infectious (fungal and parasitic) ( P < 0.01) skin problems. Cytological examination provided significantly less information ( P < 0.01) compared to the histological results in the group of other skin diseases, but there was no significant difference between the informative values of both methods comparing all cases. Significance, usefulness and necessity of histopathological and cytological methods applied in the clinical practice were justified in this study. Funding: IAMS Company.
