Abstract: The plasma cell granuloma (PCG) is a rare entity characterized by tumor lesions that may invade different tissues of the human body such as lungs, liver, spleen, orbits, pancreas and various mucous membranes. It’s appearance in mouth is strange and there are few reported cases in lip and gum as single lesions mostly. The objective of this paper is to report a case of PCG on gingiva, with the particularity of being multiple lesions that invade nearly all the labial mucosa the palatal and lingual in minor proportion and also treatment outcome and histopathological exam confirmed a diagnosis of plasma cell granuloma; it happened in a male patient of 64 years old who consult for an asymptomatic gingival hyperplasia with chronic periodontal disease was presented. Clinical and radiological examination was performed and was taken as presumptive diagnosis of plasma cell granuloma, hygienic phase was performed, excisional biopsy and gingivoplasty was performed, and the histopathological examination confirmed the initial diagnosis. Healing occurred rapidly and normally with no recurrence to date. What is known about this lesion is very scarce, its etiology and pathogenesis are still a mystery, proposing many different theories, none of these validated until now, the differential diagnosis is established with lesions of malignant trend so it is important to review histologically any reactive tumor lesion of the oral cavity.
