We report two rare cases of enchondroma protuberans originating from phalanxes.
The patients visited doctors for a palpable mass in their phalanx without any pain or discomfort.
Biopsy is the gold standard for the diagnosis of enchondroma protuberans. Radiographs usually provide important imaging information, while studied on the ultrasound manifestation of enchondroma protuberans are still limited. In our cases, significant information about ultrasound manifestation of enchondroma protuberans were presented. Sonographic examination of enchondroma protuberans revealed a hypoechoic mass located in and beyond the medullary cavity of bone through the interrupted bone cortex, and blood flow signals were usually not abundant.
Patients were subsequently referred for surgical removal and the masses were confirmed by following pathological examination.
After surgery, the patients recovered well with no relapse within 2 years.
Enchondroma protuberans is a rare form of benign enchondroma. Enchondroma protuberans can present as an intramedullary hypoechoic mass extending to the surrounding soft tissue via the discontinuous cortex line on ultrasound. Ultrasound can provide important information for the diagnosis of enchondroma protuberans.
我们报告了两例罕见的起源于指骨的骨外生骨疣病例。
患者因指骨处可触及肿块就诊，无任何疼痛或不适。
活检是诊断骨外生骨疣的金标准。X线片通常能提供重要的影像学信息，而关于骨外生骨疣超声表现的研究仍然有限。在我们的病例中，展示了有关骨外生骨疣超声表现的重要信息。骨外生骨疣的超声检查显示，低回声肿块通过中断的骨皮质位于骨髓腔内及骨髓腔外，血流信号通常不丰富。
患者随后被转诊进行手术切除，术后病理检查证实为肿块。
术后患者恢复良好，两年内无复发。
骨外生骨疣是一种罕见的良性内生软骨瘤形式。骨外生骨疣在超声上可表现为髓内低回声肿块，通过不连续的皮质线延伸至周围软组织。超声可为骨外生骨疣的诊断提供重要信息。
