Primary jejunal osteosarcoma associated with a surgical sponge in a dog.
Primary jejunal osteosarcoma was diagnosed in association with a surgical sponge in a dog. The tumor was biologically aggressive, resulting in widespread metastasis throughout the abdomen within 2 months of surgical resection. Microscopic examination of the resected osteosarcoma revealed strands of gauze material throughout the tumor mass. It was theorized that the presence of a sponge foreign body may have resulted in malignant transformation of adjacent tissues similar to what has been reported to occur after internal fixation of some long-bone fractures.
