Introduction

Vulvovaginal concerns are common among adolescent patients. In postmenarchal patients, common etiologies include poor hygiene, contact irritants, and infection.

Case

A 14-year-old transgender male presented with concerns of vulvar irritation and significant labial enlargement. Comprehensive workup including tissue biopsies and imaging suggested chronic inflammation. His clinical course was complicated by an episode of methemoglobinemia secondary to local anesthetic toxicity, at which time his care team recognized use of large quantities of Vagisil, which contains benzocaine. Ultimately, vulvar changes were recognized to be secondary to chronic Vagisil use.

Summary and Conclusion

This case highlights the potential dangers of off-the-shelf products, such as Vagisil. In patients presenting with vulvovaginal complaints, care providers should carefully screen for use of “hygiene products” as part of exposure history.

病例报告：青少年患者外阴刺激和肿胀的不常见病因

介绍

外阴阴道问题在青少年患者中很常见。在初潮后患者中，常见的病因包括卫生条件差、接触刺激物和感染。

案子

一名 14 岁的变性男性因外阴刺激和明显的阴唇增大而就诊。包括组织活检和成像在内的综合检查表明存在慢性炎症。他的临床病程因局部麻醉剂中毒继发的高铁血红蛋白血症发作而变得复杂，此时他的护理团队认识到使用了大量含有苯佐卡因的 Vagisil。最终，外阴变化被认为是继发于长期使用 Vagisil。

总结与结论

该案例凸显了 Vagisil 等现成产品的潜在危险。对于外阴阴道不适的患者，护理人员应仔细筛查是否使用“卫生用品”作为接触史的一部分。
