Plain-English summary
An 8-year-old spayed female Italian greyhound was brought in with a large mass in her abdomen. After examining her, the vet found a significant irregular mass that was not attached to any organs. During surgery, they removed a 16 cm by 12 cm by 6 cm mass, which was later identified as extraskeletal osteosarcoma (a type of bone cancer) caused by a foreign body granuloma, likely from a surgical sponge left behind during her spay surgery seven years earlier. Unfortunately, this type of cancer has a poor prognosis, especially when linked to foreign body granulomas.

Abstract
An 8 yr old spayed female Italian greyhound was presented with a mass in the cranial abdomen. Preliminary evaluation of the dog revealed a large, cavitary, irregularly shaped mass with no definitive association with any abdominal organs. During an exploratory celiotomy, a 16 cm × 12 cm × 6 cm mass was removed. On subsequent histopathology, extraskeletal osteosarcoma induced by a foreign body granuloma was diagnosed. The foreign body granuloma, based on histopathological findings, was suspected to be secondary to a retained surgical sponge from her routine ovariohysterectomy performed 7 yr prior to presentation. Animals with granulomas induced by foreign bodies can remain asymptomatic for years; however, those granulomas can progress to extraskeletal osteosarcomas, which carry a poor prognosis.
