Coincidental oral lesions in Crohn's disease

A 21-year-old patient with Crohn's disease, who was undergoing Infliximab treatment, presented at the hospital due to a painful oral mass. After confirming the absence of malignant cells through frozen sections, a complete excision of the infiltrated bone surrounding the lesion was performed. The postoperative pathology confirmed the presence of Central type giant cell granuloma in the mandible, which is distinct from non-caseating granulomas in oral CD and Infliximab-induced Sarcoidosis. As far as we are aware, this is the first to report an association between CGCG and both CD and anti-tumor necrosis factor therapy treatment.
