Background:

Plasma cell granuloma (PCG) is an uncommon pathology characterized by a red lesion and hyperplasia that has a high affinity to any soft tissue, more frequently at the lung level and in an unusual way at the oral level such as lips, tongue and gingiva as a very unique case, histologically characterized by a large number of plasma cells.

Objective:

To report a rare case of GCP in the gingiva with the approach, complications and success of its treatment.

Description of the case:

a 60-year-old female patient comes to the clinic for a red lesion at the level of the marginal and attached gingiva of the upper jaw. Intraoral examination revealed localized hyperplasia with a presumptive diagnosis of plasma cell granuloma, where radiographic examinations were performed, followed by a biopsy, confirming said diagnosis.

Conclusion:

GCP is clinically characterized by presenting gingival hypertrophy in the attached gingiva, one of the least frequent places at the oral level. This pathology, as it presents certain clinical and histological similarities, is very difficult to make a correct diagnosis of said pathology.
