Peripheral ossifying fibroma (POF) and pyogenic granuloma (PG) belong to the group of "focal reactive overgrowths," having different histomorphologic representations. The pathogenesis of POF remains controversial. It has been observed that POF in some cases may initially develop as a PG that undergoes subsequent fibrous maturation and calcification. A case of focal reactive gingival overgrowth with a recurrence is presented. Clinical, radiological and histological examinations were performed and included a detailed history of the lesions to come up with the proper diagnosis. The primary lesion was diagnosed as POF and the recurrent lesion as PG. The POF might have developed initially as PG and subsequent maturation led to the ossification of the lesion. These two lesions represent the progressive stages of the same spectrum of pathosis.
外周骨化性纤维瘤（POF）和化脓性肉芽肿（PG）属于“局灶性反应性增生”组，具有不同的组织形态学表现。POF的发病机制仍存在争议。据观察，在某些情况下，POF最初可能发展为PG，随后经历纤维成熟和钙化。本文报告一例复发性局灶性反应性牙龈增生病例。进行了临床、放射学和组织学检查，包括详细的病损病史，以做出正确诊断。原发性病损诊断为POF，复发病损诊断为PG。POF最初可能发展为PG，随后的成熟导致病损骨化。这两种病损代表了同一病理谱的进展阶段。
