A 5 years old female, mixed-breed goat was presented to clinic for evaluation of postmortem lesions because it showed evidence of paratuberculosis. At necropsy examination, whitish-yellow lobulated mass (11 × 8 × 4 cm) was found on the ileal mesentery. Histopathologically, the tumor consisted of well-differentiated fat cells with no pleomorphism and anaplasia. The cells have monovacuolated and multivacuolated cytoplasm. Mitotic figures were not observed in the mature adipocytes. On the basis of the gross and microscopical findings, the mesenteric lipoma was diagnosed.
