Successful Removal of Apocrinehydrocytoma Using Indocyanine Green and Sodium Hyaluronate

ABSTRACT

PURPOSE: To report a new modified method using a mixture of sodium hyaluronate and indocyanine green solution to facilitate the complete removal of a large conjunctival cyst. CASE SUMMARY: Two patients with a large conjunctival cyst on the bulbar conjunctiva were treated. In order to achieve complete removal, a mixture of 1% sodium hyaluonate and indocyanine green solution was injected through a 27-G needle into the cyst. The procedure provided excellent visualization of the cyst boundaries while maintaining cyst integrity allowing for an easy and complete resection. Apocrine hidrocystoma and a simple retention cyst were confirmed on histopathologic examination, respectively. CONCLUSIONS: During the removal of a large cyst, injecting a mixture of sodium hyaluronate and indocyanine green is effective in delineating the cyst capsule while preserving its integrity, thus aiding in the complete removal of the cyst wall.
