Fine-needle aspiration cytology of the canine apocrine sweat gland carcinoma

Tumors of apocrine sweat glands are uncommon in comparison to tumors of sebaceous glands in dogs. Animals older than 8?years of age are most likely to develop these tumors. The authors report a case of apocrine sweat gland carcinoma in a 2-year-old crossbred dog that was diagnosed by fine-needle aspiration cytology. The technique was shown to be helpful for the correct diagnosis and treatment approach. However, despite being time consuming, the histopathological study remains the method of choice for accurate classification of the disease.
