Abstract

INTRODUCTION

Conjunctival nevi are benign tumors that are commonly located at the nasal or temporal limbus and rarely in the fornix or tarsus. We report a case of a patient presenting with a solitary compound cystic nevus of the conjunctival fornix in the background of bilateral complexion-associated melanosis.

CASE PRESENTATION

A 71-year-old African-American female was referred for evaluation of an incidentally noted melanocytic lesion of the right conjunctival fornix. The patient underwent an excisional biopsy, revealing histological features consistent with a compound cystic nevus.

CONCLUSION

This finding is noteworthy due to the rarity of conjunctival nevi originating in the fornix. The case underscores the importance of excisional biopsy in evaluating conjunctival forniceal melanocytic lesions to exclude malignant melanoma, a critical consideration for prognosis.

摘要

引言

结膜痣是常见于鼻侧或颞侧角膜缘的良性肿瘤,很少发生于穹窿部或睑板。我们报告一例在双侧肤色相关黑素沉着背景下出现结膜穹窿部孤立性复合囊性痣的患者。

病例介绍

一名71岁的非裔美国女性因偶然发现右结膜穹窿部黑素细胞病变前来评估。患者接受了切除活检,组织学特征符合复合囊性痣。

结论

由于起源于穹窿部的结膜痣罕见,这一发现值得关注。该病例强调了切除活检在评估结膜穹窿部黑素细胞病变以排除恶性黑色素瘤方面的重要性,这是预后的关键考虑因素。
