RESUMEN
Soft tissue swellings of the oral cavity frequently present a diagnostic challenge because a diverse group of pathologic processes can produce such lesions. Among these lesions are a group of reactive hyperplasia, which develop in response to a chronic, recurring tissue injury that stimulates an exuberant or excessive tissue repair response, and pyogenic granuloma is one of them. It is a reactional response to constant minor trauma or may be related to hormonal changes. It preferentially affects the gingiva followed by lips, tongue, buccal mucosa, and palate. It is commonly seen in young adults. The treatment is excision of the lesion. This case report describes the clinical and histopathological features of a pyogenic granuloma, in a 20-year-old male patient.
