AIMS To assess the incidence of foreign body giant cell reactions and ossification in benign/melanocytic naevi; and to examine their pathological features to gain an insight into their pathogenesis. METHODS Intradermal (n = 185) and compound naevi (n = 110) from a routine histology service, together with 60 naevi submitted to an ophthalmic pathologist, were examined for foreign body reactions...

The use of substances to augment soft tissues as aesthetic purpose is associated with, among other undesirable effects, the appearance of foreign body granulomas. The improvements made to these substances have reduced the incidence of adverse reactions, but not eliminated them. We present five cases of foreign body reactions to three different products, dimethylpolysiloxane (silicone), bovine c...

Granulomatous lesions of the stomach, peritoneum, and lungs caused by an unidentified foreign body have been described at intervals for the past 30 years. Muir (1929) illustrates a nodule from the peritoneal cavity showing giant cell and macrophage reaction around a foreign body probably of vegetable origin. Barnard (1940) illustrates a foreign body reaction in the lung round inhaled particles ...

purpose : to present a case of missed intraorbital wooden foreign body presented as soft tissue mass case report : we introduce a case of intraorbital wooden foreign body which presented with orbital soft tissue mass two years after trauma. a plain ct was requested which revealed a foreign body in the right orbit.conclusion : it is frequently difficult to identify and localize organic intraorbi...

Gossypiboma, an infrequent surgical complication, is a mass lesion due to a retained surgical sponge surrounded by foreign-body reaction. A 27-year-old lady presented with palpable abdominal mass five years after cesarean section. Retained foreign body was diagnosed radiologically and confirmed with operation. Retained foreign body should be in the differential diagnosis of any postoperative pa...

Figure 1. Intermediate-power microscopy shows the eosinophilic colloid-filled follicles at the periphery. In many follicles in the center, the epithelium has been replaced by the inflammatory reaction and the colloid is reduced or absent. Microabscess formation with foreign-body-type giant cells can be seen. Figure 2. A: The colloid is engulfed by the ring of foreign-body-type giant cells with ...

Foreign body reactions may occur in patients who receive bioabsorbable implants during orthopedic surgery for fractures and ligament repair. The authors describe a 34-year-old man who presented with a palpable tender mass on the lateral aspect of the left knee of 1 month's duration. He underwent posterior cruciate ligament and posterolateral corner reconstruction 3 years earlier. Physical exami...

The sterile sponges may lose a significant amount of lint during their routine use in surgery, which is usually neglected. We designed an experimental model to evaluate the potential of sterile sponges to lose lint and to induce foreign body reaction in surgically created wounds. In 15 Wistar rats, separate subcutaneous pockets were created. Left-sided pockets were temporarily packed with steri...

We analysed the radiographs of 67 patients with displaced malleolar fractures treated by open reduction and internal fixation using absorbable polyglycolide rods. Seventeen patients developed a discharging inflammatory foreign-body reaction, a complication unique to these fixation devices. In 34 patients ovoid osteolytic foci, usually 5 to 10 mm in diameter, appeared within the implant channels...
