DESCRIPTIVE AND HISTOPATHOLOGIC ANALYSIS OF BENIGN ORAL NEURAL LESIONS DIAGNOSED

Objective To perform a descriptive and histopathologic analysis of benign oral neural lesions diagnosed between 2014 and 2017 in the oral pathology laboratory. Study Design The following information was collected from the requisitions: Age, sex, location, clinical aspect, type of biopsy, and histopathologic diagnosis. Results Twelve cases were identified of 1150 lesions analyzed: 9 (75%) of traumatic neuroma, 2 (16.6%) of schwannoma, and 1 (8.3%) of palisaded encapsulated neuroma. The mean age was 45.11 years, with 7 (58.33%) males and 5 (41.67%) females. Clinically, described 7 (58.33%) as firm nodules, 1 (8.33%) softened pedicle base lesion, 1 (8.33%) lesion of sessile soft base, 1 (8.33%) papule, and 2 (16.67%) were not described. The most frequent site was tongue 9 (75%), oral vestibule 1 (8.33%), mouth floor 1 (8.33%), and buccal mucosa 1 (8.33%). The types of biopsies were 5 (41.67%) incisional, 3 (25%) excisional, and 4 (33.33%) were not informed. Conclusions The benign oral neural lesions represent 1.04% of all diagnosed oral lesions and traumatic neuroma is the most common lesion.
