Plain-English summary
A 6-year-old female spayed Shetland Sheepdog was brought in because of a firm lump over her right shoulder that had grown significantly over the past 20 months. Initially thought to be a harmless lipoma (a type of fatty tumor), further testing with a CT scan suggested it might be something more serious. A biopsy confirmed it was an infiltrative angiolipoma, which is a benign but locally aggressive tumor. The vet successfully removed the tumor, and the dog is expected to recover well after the surgery.

Abstract
A 6-year-old female spayed Shetland Sheepdog presented for evaluation of a subcutaneous mass over the right prescapular region. The mass had been cytologically diagnosed as a lipoma by the referring veterinarian 20 months prior, but had grown significantly and was very firm. CT scan of the mass was suggestive of neoplasia; however, the tissue of origin could not be determined. Histopathologic evaluation diagnosed infiltrative angiolipoma, and marginal resection of the tumor was performed. Infiltrative angiolipomas are benign but locally aggressive neoplasms uncommonly reported in veterinary medicine. This report correlates the clinical, CT, and histopathologic characteristics of an infiltrative angiolipoma.
