Cytology of the cutaneous and subcutaneous lesions of the dog and cat

Cytology is a useful, noninvasive, inexpensive diagnostic tool that is particularly suitable for veterinary dermatology. Fine-needle aspirations, scrapings, swabs and impressions smears of dogs and cats cutaneous and subcutaneous lesions are one of the most commonly submitted cytology samples from veterinary patients. Representative samples can yield immediate diagnostic results classifying lesions as inflammatory or neoplastic. This allows rapid and proper treatment avoiding additional diagnostic costs what is nowadays very important issue in small animal practice due to economic crisis. Confident cytologic interpretation of specimens obtained from dogs and cats cutaneous and subcutaneous lesions requires comparative approach based on animal species peculiarity and epidemiological data specific for neoplastic and infectious diseases in these species. We present most common cytologic diagnoses of neoplastic, non- neoplastic and inflammatory diseases of cutaneous and subcutaneous lesions in dogs and cats from Croatia collected during six years of diagnostic work in Department of Veterinary Pathology Zagreb. Most prevalent neoplastic lesions were round cell neoplasms (mastocytoma, histiocytoma, plasmacytoma), benign tumors of follicular origin, squamous cell carcinoma, sebaceous and hepatoid gland neoplasms, anal sac gland carcinoma, hemangiopericytoma, fibrosarcoma, lipoma. In the group of inflammatory lesions, we want to emphasize cutaneous Mycobacterium infections in cat, nodular leishmaniosis in dog and cutaneous dirofilariosis which are diseases of regional epidemiological importance.
