Elastofibroma is a well known pseudotumorous process that characteristically occurs in the scapular region in the presence of trauma or injury. Additionally, numerous other sites of origin have been reported in the literature, but to date none have presented in the oral cavity. A 56-year-old female presented with a painless small mass in the floor of the mouth. A longstanding history of trauma to the region was noted. Histopathologic examination revealed the mass to be comprised of a haphazard array of collagen and elastic fibers in a myxomatous background. The elastic nature of the fibers was confirmed by an elastic stain. The diagnosis of elastofibroma was rendered based upon the microscopic findings. This represents the first reported case of elastofibroma of the oral cavity.
弹力纤维瘤是一种广为人知的假瘤性病变，其特征性地发生于肩胛区，常伴有创伤或损伤。此外，文献中还报道了许多其他起源部位，但迄今为止，尚无发生于口腔的病例。一名56岁女性患者，口底出现无痛性小肿块。该区域有长期创伤史。组织病理学检查显示，肿块由黏液样背景中杂乱排列的胶原纤维和弹力纤维组成。弹力纤维染色证实了纤维的弹性性质。根据显微镜检查结果作出弹力纤维瘤的诊断。这是首例报道的口腔弹力纤维瘤病例。
