초록
목적: 안구 결막에 발생한 아포크린한선낭종 증례를 경험하여 이를 보고하고자 한다. 증례요약: 36세 남자 환자가 내원 1주일 전에 발견한 좌안 결막에 생긴 종괴로 내원하였다. 초진 시 세극등현미경검사에서 좌안 결막 이측 부위에 경계가 비교적 잘 지어진 분홍색 종괴가 관찰되었다. 안와 전산화단층촬영에서 비교적 경계가 분명한 4×10×21 mm 크기의 조영증강된 종괴가 좌측 결막 부위 상이측 및 하이측에 위치하고 있었다. 결막 유표피낭종 의심 하에 좌안 결막 낭성 종괴 절제생검술을 시행하였고, 병리조직검사에서 아포크린한선낭종으로 진단되었다. 결론: 안구 결막에 발생한 아포크린한선낭종은 극히 드물지만, 결막 종괴의 감별진단에서 고려되어야 할 것으로 여겨진다.
Abstract
Purpose: To present a case of apocrine hidrocystoma occurring that occurred in the bulbar conjunctiva. Case summary: A 36-year-old male patient presented with a mass in the left conjunctiva noted a week prior to his visit. During the initial physical examination, slit-lamp examination revealed a relatively well-demarcated pink mass in the lateral part of the left bulbar conjunctiva. Orbital computed tomography showed a well-defined, contrast-enhancing mass measuring 4 × 10 × 21 mm in the left lateral conjunctival area, suggestive of a conjunctival epidermoid cyst. An excisional biopsy of the cystic mass was performed. Histopathological examination confirmed that the lesion was an apocrine hidrocystoma. Conclusions: Apocrine hidrocystoma occurring in the bulbar conjunctiva is extremely rare but should be considered in the differential diagnosis of a conjunctival cyst or mass.
