Seventy-five surgically excised canine gum neoplasms, which had previously been diagnosed as epulis or ameloblastoma, were reclassified on the basis of their presumed tissue of origin. They included 42 tumours of fibroblastic origin, which contained small foci of odontogenic epithelium and were classified as peripheral odontogenic fibroma, whilst 31 epithelial tumours were classified as basal cell carcinomas arising from the gum epithelium. Two epithelial tumours which apparently arose within the bone of the mandible and were not connected with the surface mucosa were classified as ameloblastomas. Follow-up studies after surgery revealed a recurrence rate of 17 per cent for the odontogenic fibromas and 50 per cent for basal cell carcinomas. Neither of the ameloblastomas, which were initially treated by radical excision, recurred locally and no metastases were detected from any of these tumours.
75例经手术切除的犬牙龈肿瘤，之前被诊断为牙龈瘤或成釉细胞瘤，现根据其推测的组织起源重新分类。其中包括42例成纤维细胞起源的肿瘤，含有小灶性牙源性上皮，被分类为外周性牙源性纤维瘤，而31例上皮性肿瘤被分类为起源于牙龈上皮的基底细胞癌。2例明显起源于下颌骨内且与表面黏膜无连接的上皮性肿瘤被分类为成釉细胞瘤。手术后的随访研究显示，牙源性纤维瘤的复发率为17%，基底细胞癌的复发率为50%。最初接受根治性切除的成釉细胞瘤均未局部复发，且未检测到任何这些肿瘤发生转移。
