Elastofibroma: the initial report in the oral mucosa

Abstract

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.
