RATIONALE
A gouty tophus, arising from the deposition of monosodium urate crystals (MSU), rarely occurs in the nasal bridge. There have been only 7 documented cases of a gouty tophus in the nasal bridge from 1978 to 2018 in English-language literature.
PATIENT CONCERNS
A 65-year-old male had a chief complaint of a lump in the nasal bridge that was slowly growing for over 1 year.
DIAGNOSIS
MSU crystals were confirmed through ultrasonography (US) and pathological examinations.
INTERVENTIONS
A cosmetically less destructive method, ultrasound-guided fine needle aspiration cytology (FNAC) was used to approach the mass lesion of nasal bridge.
OUTCOMES
The diagnosis was confirmed as a gouty tophus without performing a nasal subdermal exploration.
LESSONS
This case report is the first use of US with FNAC to approach and diagnosed a gouty tophus in the nasal bridge.
原理
痛风石由尿酸钠晶体（MSU）沉积形成，很少出现在鼻梁处。1978年至2018年，英文文献中仅记录了7例鼻梁处痛风石的病例。
患者情况
一名65岁男性，主要诉求为鼻梁处有一肿块，缓慢生长超过1年。
诊断
通过超声检查（US）和病理检查确诊为MSU晶体。
干预措施
采用一种对外观破坏较小的方法，即超声引导下细针穿刺抽吸细胞学检查（FNAC）来处理鼻梁处的肿块病变。
结果
未进行鼻皮下探查即确诊为痛风石。
经验教训
本病例报告首次使用超声联合FNAC来处理和诊断鼻梁处的痛风石。
