Oral Fibrous Hyperplasia of the Anterior Hard Palate Characterized by Masson's Trichrome Staining: A Case Report

Abstract

Fibrous hyperplasia is the most common reactive lesion that can occur in the gingiva. Its manifestation is linked to chronic irritation, such as biofilm and dental calculus, trauma, or poorly fitted restorations. Given the similarity in characteristics between reactive hyperplastic lesions and various pathologies, timely diagnosis is essential. The aim of this clinical case report is to describe the diagnostic approach, clinical management, and histopathological findings of a case of oral fibrous hyperplasia. A 59-year-old male patient presented with a mass in the hard palate area. Clinical examination identified a pedunculated, nodular lesion with a smooth surface and pale pink coloration. First, periodontal therapy was implemented to remove irritating factors; second, the lesion was excised to perform a biopsy. The diagnosis of fibrous hyperplasia was confirmed through histopathological analysis, and the characterization was completed with Masson’s trichrome staining. Follow-up revealed an adequate resolution. For the management of fibrous hyperplasia, surgical removal combined with the elimination of etiological factors is the appropriate treatment of choice.
