Herein, we report an unusual presentation of a 38-year-old heathy lady with a painless slowly growing lesion in the volar aspect of her left distal forearm reaching the thenar area for >15 years. Magnetic resonance imaging of the lesion showed multilobulated soft tissue mass with low and high signal in T1- and T2-weighted images with homogenous contrast enhancement. Additionally, a stable serpiginous bony lesion was noted in the first metacarpal bone showing low T1 and high T2 signals with peripheral enhancement. Histopathological examination was consistent with cylindroma and enchondroma, respectively. The patient had full recovery with no recurrence at a 1-year follow-up visit. While enchondroma is the most common benign tumor of the hand, sporadic dermal cylindroma, in contrast, rarely affects the upper extremity. The coexistence of these two pathological entities was not previously reported and it may complicate the diagnosis.
在此，我们报告一位38岁健康女性的罕见病例，其左前臂远端掌侧有一无痛性缓慢生长的肿物，累及大鱼际区域超过15年。该肿物的磁共振成像显示为多叶状软组织肿块，在T1加权像上呈低信号，在T2加权像上呈高信号，增强扫描呈均匀强化。此外，在第一掌骨发现一个稳定的匐行性骨质病变，T1加权像呈低信号，T2加权像呈高信号，周边强化。组织病理学检查分别符合圆柱瘤和内生软骨瘤。患者在1年的随访中完全康复，无复发。内生软骨瘤是手部最常见的良性肿瘤，而散发性皮肤圆柱瘤很少累及上肢。这两种病理实体并存此前未见报道，可能会使诊断复杂化。
