Body cavity lipomas in six dogs

Histologically confirmed lipomas were surgically removed from the thoracic or abdominal cavities of six dogs. Three dogs had a large intra‐abdominal mass causing severe abdominal distension. Two dogs had a mass extending into the pelvic canal, compressing the colon and causing obstipation. One dog with an intrathoracic mass had a history of coughing and intermittent cyanosis. All dogs had complete resolution of signs after surgical resection of the tumour. Recurrence occurred in one dog with an abdominal lipoma, two years after the initial surgery. This recurrent lipoma was treated successfully by surgical resection.
