Abstract

Postoperative suture granuloma have rarely been reported in animals. Eight biopsy masses from testes areas of neutralized dogs were diagnosed as suture granuloma. The suture granuloma occurred at any time from several weeks to a few years after surgery and appeared to be testicular tumors by macroscopic examination. The granulomas were classified into three types based on the histopathological findings. The first type of pyogranuloma was mainly composed of neutrophils, macrophages, and suture fragments. The second type was chronic necrotizing granuloma which was well demarcated by fibrous connective tissues and was composed of a few suture fragments, macrophages and central fibrinoid necrosis. The third type of granuloma had a poorly defined margin with scarcely observed suture fragments and central necrosis in the tissue. These histopathological findings suggested that various types of suture granuloma may be caused by suture materials and could even appear long after surgery.
