Abstract：
BACKGROUND: A 10-year-old castrated male Maltese dog was presented with chronic swelling that had been present for at least 5 years in the medial canthus of the right eye (OD).
OBJECTIVE: To describe the treatment outcome of dacryops with dacryolithiasis.
METHODS: Bilateral patency of the nasolacrimal system was confirmed by flushing of both upper and lower puncta. Ocular ultrasonography revealed a well-defined, oval-shaped, heterogeneous mass with several hyperechoic foci. Dacryocystorhinography revealed no connection between the mass and lacrimal canaliculus. Gentle blunt dissection of the fibrous connective tissue around the cystic mass was performed. The mass was removed, which intraluminally contained multiple calculi.
RESULTS: Histopathologically, the cystic structure was lined by simple cuboidal epithelium and surrounded by smooth muscle actin positive myoepithelial cells consistent with dacryops derived from the lacrimal glandular ductal system. In addition, several spherical basophilic minerals were observed in the lumen, which were identified as dacryoliths.
CONCLUSIONS: Surgical removal of this dacryops with dacryolithiasis was curative without recurrence after four months.

摘要：
一只10岁的cast割雄性马耳他犬出现慢性肿胀，在右眼内侧can（OD）中至少存在5年。
描述泪囊合并泪囊结石的治疗结果。
通过上泪点和下泪点的冲洗证实了鼻泪系统的双侧通畅。眼部超声检查显示，椭圆形,具有多个高回声病灶的异质块。泪囊造影显示肿块与泪小管之间没有联系。对囊性肿块周围的纤维结缔组织进行温和钝性解剖。肿块被移除，铝内含有多个结石。
组织病理学，囊性结构由简单的立方上皮排列，并被平滑肌肌动蛋白阳性肌上皮细胞包围，与泪腺导管系统衍生的泪囊一致。此外,在管腔中观察到几种球形嗜碱性矿物，被鉴定为泪石。
手术切除泪液结石4个月后无复发。
