A delayed foreign body reaction to polypropylene sutures has not been previously reported following tendon repair.
A 12-year old boy underwent tendon transfer. Tendon repair was done using polypropylene sutures. Five months later, a slowly growing granuloma was seen at the tendon repair site. Skin testing did not show an allergic reaction to the suture. Excision of the granuloma and removal of sutures were curative. Histology confirmed a foreign body granuloma.
A mass developing several months at the site of tendon repair indicates either an allergic or foreign body reaction to the suture. Skin testing (for allergy) and histological examination of the mass differentiate allergic from foreign body reactions.
We report on a rare case of a giant granuloma caused by a delayed foreign body reaction to polypropylene sutures used in tendon repair.
肌腱修复术后对聚丙烯缝线出现延迟性异物反应此前未见报道。
一名12岁男孩接受了肌腱转移术。肌腱修复采用聚丙烯缝线。五个月后，在肌腱修复部位可见一个缓慢生长的肉芽肿。皮肤试验未显示对缝线有过敏反应。肉芽肿切除及缝线拆除后治愈。组织学检查证实为异物肉芽肿。
肌腱修复部位数月后出现肿物提示对缝线有过敏或异物反应。皮肤试验（用于检测过敏）及肿物的组织学检查可区分过敏反应与异物反应。
我们报告了一例罕见的因肌腱修复中使用的聚丙烯缝线发生延迟性异物反应导致巨大肉芽肿的病例。
