A histopathological study was performed on forty canines diagnosed as having post-operative suture granuloma. Seventeen of the forty cases were miniature dachshund, twenty-two were male and eighteen female. The median age was 5.04 years. Suture sites were located in the inguinal region, subcutis of the abdomen and the abdominal cavity. Twenty-seven of the forty had been castrated or spayed. More than half of the forty samples were silk sutures, followed by absorbable multifilament sutures. Histopathologically, the lesions mainly consisted of pyogranuloma and necrotizing granuloma that contained suture materials in the center of the lesion. However nodular lesions without sutures were also observed. The lesions were more severe where silk and absorbable multifilament sutures were used than others. In the present study, it was suggested that the frequency of occurrence of suture granuloma differs by suture material and breed, and that the most common cause was a castration or spaying operation.
