Abstract

INTRODUCTION

Enchondroma protuberans (EP), a rare form of enchondroma with exophytic growth, differs radiographically from classical enchondromas and can mimic osteochondroma, periosteal chondroma, or chondrosarcoma. Proper differentiation is crucial to avoid unnecessary radical resection, as EP requires intralesional curettage rather than the surgical removal typical for osteochondromas.

CASE REPORT

A 14-year-old male presented with a progressively enlarging, painless mass on the lateral aspect of his left hand, initially noticed 4 years ago. Imaging and biopsy suggested osteochondroma, but histopathology confirmed enchondroma. Post-surgical excision and curettage, the patient reported no pain or limited range of motion at the 4-week follow-up.

CONCLUSION

Accurate diagnosis and differentiation of EP, supported by detailed radiographic and histopathological evaluation, are crucial for timely surgical intervention to prevent malignant transformation and recurrence, highlighting the need for clinical awareness and precise diagnostic protocols.

摘要

引言

骨外生软骨瘤（EP）是一种罕见的具有外生性生长的软骨瘤，在影像学上与经典软骨瘤不同，可类似骨软骨瘤、骨膜软骨瘤或软骨肉瘤。正确鉴别对于避免不必要的根治性切除至关重要，因为EP需要病灶内刮除术，而不是像骨软骨瘤那样进行手术切除。

病例报告

一名14岁男性，左手外侧有一个逐渐增大的无痛性肿块，最初于4年前发现。影像学检查和活检提示为骨软骨瘤，但组织病理学确诊为软骨瘤。手术切除及刮除术后，患者在4周随访时报告无疼痛且活动范围无受限。

结论

在详细的影像学和组织病理学评估支持下，对EP进行准确诊断和鉴别，对于及时进行手术干预以预防恶变和复发至关重要，这凸显了临床认识和精确诊断方案的必要性。
