Sialolipoma of the sublingual salivary gland in a dog – first report

Abstract

This report describes a 14-year-old Pit Bull dog presenting with a soft tissue swelling of 3-month progression in the right sublingual region. Histopathological analysis of the surgically resected specimen revealed large numbers of mature adipocytes and islets consisting of mucin-containing atrophic acini and dilated ducts surrounded by a thin fibrous capsule. Findings were consistent with sialolipoma of the sublingual salivary gland. To the authors’ knowledge, this is the first case of sialolipoma affecting the sublingual salivary gland in dogs.
