The aim of this work is to provide an overview of the only most frequent exophytic soft tissue lesions with traumatic etiology found in the daily outpatient clinic.
Background: The term oral exophytic lesions represent any pathological growth that projects above the normal contours of the oral surface epithelium. This kind of lesion are often related to traumatic insults. The most common are fibrous nodule, traumatic and peripheral ossifying fibroma, morsicatio buccarum, pyogenic and peripheral giant cell granuloma, mucocele and ranula.
Review Results: About morsicatio buccarum a work by Woo et al. examined 584 white lesions, with a temporary diagnosis of leukoplakia, and pointed out that 56 of these were actually morsicatio buccarum. Santana Santos et al. did an epidemiological study on traumatic fibromas and pointed out that on 1290 oral soft tissue lesions, 193 were traumatic fibromas, about 15%. Mucocele is often a masticatory trauma that causes a laceration of the minor salivary glands with the formation of a cystic lesion that tends to increase. From a work by Jafarzadeh et al. It has emerged that about 1/3 of the pyogenic granulomas are related to trauma, and poor oral hygiene acts as an accelerating factor.
Conclusion: Exophytic traumatic soft tissue lesions must be well identified by the clinician because of their high frequency. These lesions very often have similar clinical characteristics but different evolution. Therefore, histological confirmation is essential after excision.
Clinical Significance: These lesions can also cause a lot of concern to patients, so they need to be well treated to prevent complications. Furthermore, some of these lesions recurred more frequently than others, especially if it did not exit completely, such as in the case of the peripheral ossifying fibroma. For this reason, specific follow-up must also be set depending on the lesion diagnosed.
