Diagnostic Challenges of Traumatic Ulcerative Granuloma with Stromal Eosinophilia in the Hard Palate

Traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) is a benign lesion that may arise from the oral mucosa consisting in an ulcerative lesion usually localized in the tongue or cheek. Palate localization is very rare. Background/Objectives: The aim of this study is to describe a case of TUGSE occurring in the hard palate of an 83 y.o. female patient, manifesting as a non-painful growing palatal lesion approximately of 3.5 x 2 cm with firm consistency and a central area of erosion and erythema, the difficulties in clinical diagnosis, and the criteria for the differential diagnosis. Also, considering the rare occurrence of TUGSE in the palate, we performed a review of the literature too. Methods: A comprehensive review of the literature was conducted following the 2020 PRISMA guidelines and a total of seven records were identified as matching the inclusion criteria of this study. Results Conclusions: Although TUGSE is a benign lesion, the clinical presentation as a proliferative and ulcerative lesion may be challenging for clinicians mainly when arising in rare sites of occurrence (e.g., the hard palate).
