The feline inductive odontogenic tumor (FIOT) is a rare entity among oral tumors in cats, the cytologic features of which are not well characterized but may prove useful. A fine-needle aspiration biopsy was performed on the right mandible between the permanent canine (404) and permanent fourth premolar (408) of an 8-month-old female mongrel cat. Cytologic smears showed epithelial cells and occasional spindle cells with extracellular homogenous acidophilic material in a hematic background. The initial diagnosis of benign tumor was confirmed by histopathologic examination of the biopsy specimen. This report describes the cytologic findings in a case of FIOT.
猫诱导性牙源性肿瘤（FIOT）在猫口腔肿瘤中是一种罕见的实体，其细胞学特征尚未得到充分描述，但可能会被证明是有用的。对一只8个月大的雌性杂种猫右侧下颌骨在恒犬齿（404）和恒第四前磨牙（408）之间进行了细针穿刺活检。细胞学涂片显示上皮细胞和偶尔的梭形细胞，在血液背景中有细胞外均匀嗜酸性物质。活检标本的组织病理学检查证实了最初的良性肿瘤诊断。本报告描述了一例FIOT的细胞学发现。
