Abstract

Background

Epithelioid hemangioendothelioma (EHE) is an ultra-rare vascular sarcoma with an extremely low incidence and prevalence, particularly in children. We report the case of a 9-year-old girl diagnosed with EHE. There are limited reconstruction methods available following total talus resection for vascular endothelioma of the talus, and the use of a 3D-printed talus prosthesis in pediatric cases has not been previously documented.

Case presentation

A 9-year-old girl presented to our unit with swelling, pain, and limited mobility of the ankle for one month without an obvious cause. X-ray and CT imaging revealed osteolytic lesions in the talus, which was identified as a low-grade malignant tumor that had nearly completely invaded the talus and was surrounded by immature bone. The American Foot and Ankle Surgery Association (AOFAS) score was 75/100. We performed a total resection of the talus followed by unrestricted talus replacement. Three months post-operation, the child was able to walk unaided. Ankle function was assessed at 6 and 13 months post-surgery, with the AOFAS score improving from 75 to 91, indicating that her functional needs for daily life were largely met.

Conclusion

Following complete excision of the lesion, the immature bone surrounding the talus was successfully preserved using an unrestricted 3D-printed prosthesis during ankle reconstruction. Our patient demonstrated satisfactory ankle function during the 6-month follow-up. This method is both safe and stable, yielding promising results, particularly for juvenile patients.

儿童距骨血管内皮瘤的全距骨切除术和3D打印假体重建

深上皮样血管内皮瘤（EHE）是一种极其罕见的血管肉瘤，发病率和患病率极低，尤其是在儿童中。我们报告的情况下，9岁的女孩诊断为EHE。距骨血管内皮瘤全距骨切除术后的重建方法有限，在儿童病例中使用3d打印距骨假体以前没有记录。病例介绍：一名9岁女孩因脚踝肿胀、疼痛和活动受限一个月无明显原因而来我科就诊。x线及CT显示距骨溶骨性病变，确定为低级别恶性肿瘤，几乎完全侵入距骨，周围为未成熟骨。美国足踝外科协会（AOFAS）评分为75/100。我们进行了距骨全切除术，然后进行了无限制距骨置换。手术后三个月，孩子可以独立行走了。术后6个月和13个月对踝关节功能进行评估，AOFAS评分从75分提高到91分，表明患者的日常生活功能需求基本得到满足。结论在完全切除病变后，在踝关节重建过程中使用不受限制的3d打印假体成功地保留了距骨周围的未成熟骨。在6个月的随访中，患者表现出满意的踝关节功能。这种方法既安全又稳定，产生了有希望的结果，特别是对青少年患者。

期刊介绍： Bone Reports is an interdisciplinary forum for the rapid publication of Original Research Articles and Case Reports across basic, translational and clinical aspects of bone and mineral metabolism. The journal publishes papers that are scientifically sound, with the peer review process focused principally on verifying sound methodologies, and correct data analysis and interpretation. We welcome studies either replicating or failing to replicate a previous study, and null findings. We fulfil a critical and current need to enhance research by publishing reproducibility studies and null findings.
