Recurrent lipoma in the common calcaneal tendon sheath in a dog

A 4‐year‐old, male, neutered labrador retriever presented with a recurrent mass in the right distal pelvic limb and lameness. Clinical examination revealed a 5 cm × 4 cm mass in the common calcaneal tendon. Fine‐needle aspiration and histology from previous excision suggested lipoma. The additional investigation included computed tomography, which revealed a bi‐lobulated lipoma infiltrating the components of the common calcaneal tendon. The lipoma was surgically excised through a lateral approach to the calcaneal tendon. Blunt dissection was performed around the tendon components to remove the lipoma while preserving tendon integrity. Eight‐month follow‐up indicated no recurrence of the lipoma, and the dog was clinically sound.
