Clinical presentation, cytological findings, and surgical outcome of a suspected benign epithelial neoplasm in a dog

Epithelial neoplasms are among the most frequently encountered tumors in dogs, particularly in the skin. The cellular origin and biological behavior of these tumors can be preliminarily assessed by cytological examination and supported by ancillary diagnostic tests, whereas histopathology remains the gold standard for definitive diagnosis. This case report de-scribes a suspected epithelial neoplasm in a 7-year-old male mixed-breed dog named Zeus. Clinical evaluation and sup-porting diagnostic examinations were performed to characterize the lesion and establish a presumptive diagnosis. Complete blood count revealed leukocytosis, anemia, thrombocytopenia, and anisocytosis, while fine-needle aspiration biopsy of the mass demonstrated epithelial cell features. Collectively, these findings suggested a benign epithelial neoplasm. The case was managed by surgical excision of the mass followed by postoperative therapy.
