Introduction: Epulis is a benign, circumscribed, gingival pseudo tumor located at the neck of one tooth or two adjoining teeth. It is a gingival outgrowth resulting either from local irritation, or from hormonal or hematological variations. It is generally of small size but can reach a considerable volume leading to significant functional and aesthetic discomfort. Observation: A 12-year-old patient living in Mauritania, who presented at the odontostomatology service of the Grand Yoff General Hospital in Dakar, Senegal, a giant tumor of the gum evolving for several years. Clinical and radiological data permitted us to give a diagnosis of a giant epulis. Excision was done under general anesthesia with a good evolution noted. Discussion: Epulis generally has an evocative clinical aspect. However, when large, epulis can cause; difficulties in hygiene control, dental displacement and or mobility, aveolar bone lysis and total loss of the tooth or teeth, as well as infections. Surgical excision is the treatment method of choice. However, there can be recurrence in case of incomplete treatment. Conclusion: The giant epulis can occur at any age. It causes both aesthetic and functional damage. It is important to set up health strategies in order to facilitate their management.
