Abstract

A 12-year-old intact male Cocker spaniel dog was presented for evaluation of lethargy and abdominal distension. Clinical examination revealed a round, palpable mass in the middle of the abdomen. Abdominal computed tomography showed a round soft tissue mass ($width{\times}height{\times}length$, $25{\times}13{\times}15cm^3$) without regional invasion and distant metastasis. Cytologic evaluation of the mass revealed adipose tissue-derived cells having vacuolated cytoplasm, indistinct borders, large nucleus and ropy chromatin pattern with variable sized lipid droplets. Complete surgical resection of the mass was performed and the mass was histopathologically diagnosed as primary omental lipoma. The dog has been recovered well without any additional clinical signs, and there was no relapse over the 8 months follow-up period. The clinical features and prognosis of the dog with primary omental adipocytic tumors have been described in this report.
