Abstract

This case series describes the clinical, imaging, and histological features of 27 lesions diagnosed as a benign fibrous mass not previously described in veterinary literature. The authors propose the name gingival mucoperiosteal fibroma (GMPF) to describe these fibrous lesions found in dogs. Histologically, GMPF is characterized by a lack of odontogenic tissue and various degrees of ossification. GMPFs affect adult dogs with an average age of 95 months (range 24-156 months) and appear as expansile growths with superficial appearance matching the surrounding gingiva. The mandibular incisive region is the most commonly affected region (n = 13) and most cases have some level of bone proliferation radiographically (n = 14). Histological examination of the masses shows poorly cellular fibrous tissue with thick interwoven collagen fibers. Bony invasion by the mass was not noted, though histological proliferation of bone was seen in 17 lesions. Surgical resection was curative in all cases when performed, and no recurrence was seen at time of follow-up. Fibrous lesions of the oral cavity in dogs are poorly defined and categorized, though numerous lesions have been described in both human and veterinary literature.

牙龈粘骨膜纤维瘤--27 只狗的新型口腔纤维瘤的临床、成像和组织学回顾。
本系列病例描述了 27 例病变的临床、影像学和组织学特征,这些病变被诊断为良性纤维性肿块,而兽医文献此前并未对其进行过描述。作者提议用牙龈粘骨膜纤维瘤(GMPF)来描述这些在狗身上发现的纤维性病变。从组织学上看,GMPF 的特征是缺乏牙本质组织和不同程度的骨化。GMPF 影响平均年龄为 95 个月(24-156 个月)的成年犬,表现为扩张性生长,表面与周围牙龈一致。下颌切迹区是最常受影响的区域(13 例),大多数病例都有一定程度的骨质增生(14 例)。肿块的组织学检查显示,肿块为细胞较少的纤维组织,胶原纤维交织较厚。虽然有 17 例病例的组织学检查显示有骨质增生,但未发现肿块侵犯骨骼。所有病例的手术切除均可治愈,随访时未见复发。狗口腔纤维性病变的定义和分类都很模糊,但人类和兽医文献中都描述过许多病变。
