An abdominal fibrosarcoma surrounding a retained surgical swab was identified in a 3-year-old neutered female rottweiler clog presented with chronic inappetence and lethargy Laparotomy revealed a mass within the omentum, multiple hepatic masses and enlarged mesenteric lymph nodes The clog was humanely destroyed and submitted for necropsy examination. Microscopically, the omental mass was consistent with a sarcoma surrounding centrally located fibres of foreign material and was infiltrated by epithehoid macrophages containing intracytoplasmic fibre fragments. Sarcoma tissue was also present in mesenteric lymph nodes, liver, spleen and lungs, and some affected lymph nodes contained intralesional epithehoid macrophages with fibre fragments. Immunohistochemical and electron microscopical examinations were consistent with a diagnosis of fibrosarcoma By fibre analysis and electron microscopy, the intratumoural fibres were identified as cotton fibres with features identical to those obtained from a surgical swab. To our knowledge this is the first description of an abdominal fibrosarcoma associated with a retained surgical swab in a clog. Other examples of foreign body-associated sarcomas in the veterinary literature are vaccine- and implant-induced sarcomas.
