Foreign Body Granuloma
Penetration of foreign bodies may present a diagnostic challenge to the surgeon. The foreign body granuloma is a biological response of tissue to any foreign body in the tissue. The pathway of arriving to the diagnosis of foreign body granuloma becomes difficult when patient presents with non specific symptoms such as pain/ swelling, and in history- no recollection of previous trauma. It can be of two types- a) Iatrogenic gossypiboma by retained surgical sponge intra-operatively b) Granulation by a penetrating foreign body such as wooden splinter or other materials. -The most frequent reported injury is to hand, thigh, knee and feet; these may be limited to soft tissue of may be intra articular. The time and type of presentation varies according to the immune status of the individual. In cases, where history of trauma is uncertain, the presentation is very late and the radiographic appearance may be confusing - Median time of presentation: 4 months to 20 years
