月骨内表皮囊肿误诊为内生软骨瘤:1例报告和综述

Epidermal cyst of lunate bone misdiagnosed as endophytic chondroma: a case report and literature review

摘要:

骨内表皮样囊肿 (intraosseous epidermoid cyst, IEC) 是一种罕见的、非肿瘤性的良性病变，最常见的部位是远端指骨。骨内表皮样囊肿在影像学上易与内生性软骨瘤相混淆。本文报告了本院骨科诊治的 1 例月骨内表皮样囊肿误诊为内生性软骨瘤的患者，采用病灶刮除、无水酒精灭活、胶原蛋白海绵填充术进行治疗。作者通过对该例患者的诊治体会，并结合文献回顾对 IEC 的临床特点、诊断标准与治疗原则进行总结，旨在为月骨内表皮样囊肿的研究与诊治提供参考。

Abstract:

Intraosseous epidermoid cyst (IEC) is a rare, non-neoplastic benign lesion with the most common site involving the distal phalanx. Intraosseous epidermoid cyst is prone to be confused with endophytic chondroma in imaging. In this paper, we reported a case of epidermoid cyst of lunate misdiagnosed as endophytic chondroma in the orthopedic department of our hospital. We used lesion curettage, anhydrous alcohol inactivation and collagen sponge filling to treat the patient. In addition, a thorough literature review was done to summa- rize the clinical features, diagnostic criteria and treatment principles of IEC to provide reference for diagnosis and treatment of epidermoid cyst of lunate.
