A 32-year-old man suffered sharp trauma to the volar aspect of the wrist. A lacerated tendon found on exploration had been left unrepaired and the skin closed primarily. A few months later the patient presented with a nodule at the same site. Reoperation demonstrated a 2 X 1 cm nodule bridging the gap between the stumps of the previously severed palmaris longus tendon. Pathologic examination of the nodule revealed the typical microscopic appearance of giant cell tumor of tendon sheath (GCTTS) in continuity with the lacerated tendon. The literature regarding the relationship of trauma to the development of GCTTS presents interesting controversy about whether this lesion is reparative or neoplastic.
一名32岁男性手腕掌侧遭受锐器伤。探查发现一条肌腱断裂，未予修复，直接缝合了皮肤。几个月后，患者在同一部位出现一个结节。再次手术发现一个2×1厘米的结节，连接着先前切断的掌长肌腱断端之间的间隙。对该结节进行病理检查，发现其具有腱鞘巨细胞瘤（GCTTS）的典型微观表现，且与断裂的肌腱相连。关于创伤与GCTTS发生之间的关系，文献中存在有趣的争议，即这种病变是修复性的还是肿瘤性的。
