Benign fibrous histiocytomas (BFH) of the skin are common lesions, although they only rarely involve the oral mucosa. This article presents 3 additional cases of BFH of the oral mucosa, with a review of previously published cases. Although a malignant variant of BFH also exists, the present review focuses only on benign lesions. The clinical presentation, diagnosis, histopathological and immunohistochemical features of BFH are discussed. According to the present analysis, the majority of oral mucosal BFH have occurred in middle-aged and elderly patients, with a slight female predilection. Within the oral cavity, BHF may occur at any mucosal site, including the lips, tongue, buccal mucosa, mandibular and maxillary gingiva as well as the palate. Histopathology is essential to diagnose the lesion, while immunohistochemical investigations may be utilized to exclude the histopathological differential diagnoses such as juvenile xanthogranulomas and nevi. This review also revealed total excision as the treatment of choice for BFH, with a very good prognosis and an extremely low rate of relapse.
The aim of this study was to evaluate the accuracy and reliability of the hand drawn cephalometric tracing technique for predicting the soft-tissue profile and their association with subjective evaluation. Distances from 8 soft-tissue landmarks to X and Y reference lines were determined on planned versus actual cephalometric profiles of 30 patients. The subjective evaluation was assessed by comparing pairs of related versus unrelated profiles by professional and nonprofessionals.The accuracy of all linear measurements was high. Mean differences were not significant for all landmarks, except for stomion on the horizontal axis (P < 0.01). Mean difference of similarity scores between related versus unrelated profiles was significant (P < 0.01). The higher objective distance over all cephalometric landmarks was associated with lower subjective similarity scores (P < 0.01).This study has demonstrated that the hand drawn cephalometric tracing technique can be accurately and reliably executed and that these results were positively associated with subjective evaluation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
