Liposarcoma associated with a glass foreign body in a dog.

An 11-year-old spayed female mixed-breed dog was referred for evaluation of a mass on the right forelimb of 4 months' duration. Cytologic examination of a fine-needle aspirate of the mass resulted in a diagnosis of liposarcoma. The 3 x 3 x 1.5-cm firm mass was surgically removed. Histopathologic observations confirmed the diagnosis of liposarcoma. During processing, a 1 x 0.8-cm piece of glass was found within the mass. Association between a glass foreign body and liposarcoma is discussed.
