Granulomatous Reaction in Jugal Mucosa: A Foreign Body Case

Introduction: Foreign bodies may be dormant and remain in the soft tissue for years without causing damage to adjacent structures, but it can make a granulomatous foreign body reaction. A granuloma is a distinct, compact microscopic structure composed of epithelioid-shaped macrophages typically surrounded by a rim of lymphocytes and filled with fibroblasts and collagen. Granulomatous inflammation of oral soft and hard tissues is an uncommon occurrence. Patients present often with oral pain and signs of inflammation with purulent discharge. However, sometimes it has been seen asymptomatic, becoming a difficult diagnosis with several differential diagnoses as sarcoidosis, Crohn disease, and others.

Objectives: Expose a case of foreign body in jugal mucous that could get mixed up with any other diagnosis, if a complete anamnesis and a well done biopsy was not taken.

Resumed Report: A 74-year-old female patient with multiple painless nodules in jugal mucosa, with progressive growth during the last 2 months, after performing a dental treatment. It discusses the clinical characteristics and differential diagnosis of granulomatous lesions of the oral cavity, based on the literature review, that were disposed with the complete anamnesis.

Conclusion: Besides the importance of histopathlogical examination, we ratify the importance of complete patient’s history, questioning any pathology in family, surgical procedures, and other body changes that lead to diagnostic hypothesis.
