A 7-year-old Persian cat was evaluated for recurrence of multiple cystic periocular masses. A number of cyst-like lesions had been resected from the left eyelids 18 months earlier, with lesions recurring within 6 months after surgery. The cat had blepharospasm and signs of discomfort following rupture of the largest cyst the day prior to examination. Previous histologic examination of the cysts had revealed apocrine hidrocystomas.
Multiple pigmented nodules were seen around the skin of the upper and lower left eyelids. The nodules were brownish to black, round, soft, and fluid-filled. Signs of pain were not evident during palpation of the nodules.
The largest cyst on the upper eyelid was removed by means of a V-shaped full-thickness excision. Histologic and immunohistochemical examination of the excised tissue confirmed the diagnosis of apocrine hidrocystoma. The remaining periocular cysts were surgically debrided and then treated topically with 20% trichloroacetic acid. All lesions healed rapidly without any signs of discomfort. During a recheck examination 12 months later, the upper and lower left eyelids appeared morphologically normal, and there was no evidence of recurrence.
Findings suggested that chemical ablation with trichloroacetic acid may be a useful treatment for apocrine hidrocystomas in cats.
一只7岁的波斯猫因多发性囊性眼周肿物复发前来评估。18个月前曾从左眼睑切除多个囊肿样病变，术后6个月内病变复发。在检查前一天，最大的囊肿破裂后，这只猫出现了眼睑痉挛和不适症状。此前对囊肿的组织学检查显示为大汗腺囊瘤。
在左上下眼睑皮肤周围可见多个色素沉着结节。结节呈棕褐色至黑色，圆形，质地柔软，充满液体。触诊结节时未发现明显疼痛迹象。
通过V形全层切除术切除上眼睑最大的囊肿。对切除组织进行组织学和免疫组化检查，确诊为大汗腺囊瘤。其余眼周囊肿进行手术清创，然后局部用20%三氯乙酸治疗。所有病变均迅速愈合，无任何不适迹象。在12个月后的复查中，左上下眼睑形态正常，无复发迹象。
研究结果表明，用三氯乙酸进行化学消融可能是治疗猫大汗腺囊瘤的一种有效方法。
