The extraosseous/peripheral odontogenic fibroma (E/POF) is a benign mesenchymal odontogenic tumour found on the gingival surface with clinical characteristics identical to those of reactive lesions. A histopathological analysis is the only method for determining the difference between reactive lesions and these neoplastic lesions, whose recurrence potential varies between 38.9% and 50%, highlighting the importance of correct diagnosis. The following report describes an E/POF case with a clear cells component, as well as a long-term follow-up treatment, which we emphasise due to its potential for recurrence.
