Flexor Digitorum Profundus Irritation and Pseudotumour Formation Ten Years after a Penetrating Glass Injury

Abstract

Retained foreign bodies inside the soft tissue following penetrating injuries are common. Late onset of symptoms and complications are possible in these cases. In the present report, we present a case of late flexor digitorum profundus irritation and pseudotumour formation caused by a retained glass piece 10 years after the injury. Pseudotumour is formed by reaction to the retained material as an enlarged portion of tissue that resembles a tumour. The complaints were completely improved soon after removal of the foreign material. Retained soft tissue foreign bodies should be suspected in differential diagnosis of soft tissue masses. History of a penetrating trauma should be questioned persistently. The authors recommend the removal of retained foreign bodies with sharp edges to avoid further injury to the surrounding anatomical structures.
