Plain-English summary
This report discusses rare types of tumors called angiolipomas, which are made up of fat tissue and blood vessels, found in two dogs and one cat. The tumors were mostly located on the chest area of middle-aged animals. One of the tumors in the cat was a unique type called angiofibrolipoma, which also had some connective tissue, while the infiltrative angiolipoma in one of the dogs was found outside the muscle but affected the muscle tissue nearby. These tumors caused damage to the muscle fibers, but the report does not specify the treatment or outcome for these cases.
Abstract
Variants of lipoma are uncommon, although fibrolipoma and infiltrative lipoma have been well documented. This report describes two cases of rare angiolipoma in dogs and the first documentation of angiofibrolipoma and infiltrating angiolipoma in a cat and a dog, respectively. Tumors were solitary, and most were located on the thorax of middle-aged patients. Angiolipomas were composed of mature adipose tissue mixed with variable numbers of blood vessels. In addition to the adipose and vascular components, the angiofibrolipoma contained bundles of collagenous connective tissue. The infiltrative angiolipoma had a primary mass external to the muscle and was histologically similar to a mixed intramuscular hemangioma that was confined to the muscle. Both disrupted bundles of striated muscle and were associated with segmental degeneration and loss of myofibers.
