Irrational Fibroma in the Central Dorsum of the Tongue: A Case Report of a Rare Location

Introduction:Oral fibroma, also known as traumatic fibroma, irritational fibroma, or focal fibrous hyperplasia, is a benign exophytic lesion that typically arises following trauma. Fibroma is the most common benign soft-tissue neoplasm in the oral cavity. Aim of Reporting This Case: The aim of reporting this case is to highlight the unusual location of a traumatic fibroma on the central dorsum of the tongue. Case Presentation: A 55-year-old patient presented to the oral medicine clinic with a lesion on his tongue that developed after drinking a hot liquid. Clinical examination revealed a smooth, round, nodular lesion located in the central area of the dorsum of the tongue, measuring approximately 0.5 × 0.3 cm in diameter. An excisional biopsy was performed, which revealed a nodular lesion lined by papillary keratinized stratified squamous epithelium. The underlying connective tissue showed thick fibrous bundles, giant fibroblast cells, and scattered small blood vessels. So, the final diagnosis for this case was irritational fibroma. Conclusion:This case demonstrates an oral fibroma in an unusual location on the dorsum of the tongue following the consumption of a hot liquid. Oral fibroma is a benign neoplasm, and trauma is the most common cause. Increased awareness of this lesion is essential, as it is one of the most common benign soft-tissue neoplasms in the oral cavity.
