A lipoma is a benign tumor which consists of matured fat cells, and the tumor has a capusule and the mobility. On the other hand, infiltrative lipoma in lipoma do not have a capsule and fat cells invade in the vicinity of the deep skin and skeletal muscle, causing pain and gait disturbance. In December 2017, a calf (Japanese black, male, 6-month-old) in a farm in Yamaguchi Prefecture showed bloat and astasia. At necropsy, abomasal pylorus revealed a tumor protruding into the lumen of approximately 3 × 2 cm in size. Infiltrative lipoma with abomasal mucosal lesions was observed in the histopathology. There are few reports of infiltrative lipoma in abomasal of ruminants, and it is a rare case. For the report of infiltrative lipoma with abomasal mucosal lesion in a lamb similar to this case, it was suggested that infiltrative lipoma was associated with abomasal mucosal lesion.
