An unusual case of fibromatosis of the dominant left flexor pollicus longus (FPL) in a thirteen year old schoolboy. Initially presenting with pain in the thenar eminence and difficulty flexing the metacarpal phalangeal joint (MPJ), other symptoms include locking, triggering and difficulty writing. MRI showed a 4cm segment of thickened abnormal tendon. Intra-operatively three 1cm nodules were excised from the FPL while preserving the tendon. Histopathology reported the nodules as fibromatosis. A literature search revealed that this has not previously been reported although symptomatic tendon sheath fibromas have. Our patient achieved a good result following surgical intervention and the two year review has shown no complications.
一名13岁男学生左侧拇长屈肌（FPL）发生罕见的纤维瘤病病例。最初表现为大鱼际疼痛及掌指关节（MPJ）屈曲困难，其他症状包括卡顿、扳机指及书写困难。磁共振成像（MRI）显示一段4厘米长的增厚异常肌腱。手术中从拇长屈肌上切除了3个1厘米的结节，同时保留了肌腱。组织病理学报告这些结节为纤维瘤病。文献检索显示，此前虽有症状性腱鞘纤维瘤的报道，但该病例此前未见报道。我们的患者手术干预后效果良好，两年复查未出现并发症。
