RATIONALE
Chondroid syringoma (CS) occurs mostly on the face and neck, and rarely occurs in the toe. Malignant CS is invasive, grows quickly, and has a high recurrence rate. The presence of a bilobed CS in 1 toe has never been reported in the literature.
PATIENT CONCERNS
A 72-year-old male patient presented with a mass in a third toe of his right foot. The mass had slowly grown in 2 years. He felt mild pain and the mass occupied most of the tip of the toe.
DIAGNOSES
Radiographs showed a large soft-tissue mass in the third toe of his right foot without any bone destruction. Ultrasonogram showed 2 partly fused hypoechoic masses within the lesion. The mass was therefore diagnosed as a benign CS.
INTERVENTIONS
We amputated the toe with the mass under local anesthesia. The postoperative pathohistological examinations confirmed that the lesion was a bipartite CS exhibiting active cellular proliferation.
OUTCOMES
Two years after surgery, there was no tumor recurrence.
LESSONS
CS can also present as multiple adjacent masses. Complete surgical resection and long-term follow-up are essential.
原理
软骨样汗腺腺瘤（CS）多发生于面部和颈部，极少发生于脚趾。恶性CS具有侵袭性，生长迅速，复发率高。文献中从未报道过1个脚趾出现双叶状CS的情况。
患者情况
一名72岁男性患者，右足第三趾出现肿物。该肿物在2年内缓慢生长。他感到轻度疼痛，肿物占据了大部分趾尖。
诊断
X线片显示右足第三趾有一个大的软组织肿物，无任何骨质破坏。超声检查显示病变内有2个部分融合的低回声肿物。因此，该肿物被诊断为良性CS。
干预措施
我们在局部麻醉下切除了有肿物的脚趾。术后病理组织学检查证实病变为二分叶状CS，表现为活跃的细胞增殖。
结果
术后2年，无肿瘤复发。
经验教训
CS也可表现为多个相邻肿物。完整的手术切除和长期随访至关重要。
