Traumatic Ulcerative Granuloma with Stromal Eosinophilia Treated with Intralesional Injections of Triamcinolone Acetonide: A Case Report

Background and Clinical Significance: Traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) of the oral cavity is a chronic, rapidly developing mucosal lesion with an unclear pathogenesis, manifesting as a solitary ulcer. Given the malignant clinical appearance of the lesions, it is crucial to ensure the accuracy of the diagnosis to avoid unnecessary invasive surgical interventions. Case Presentation: We present a case involving a 69-year-old female affected by a wide, painful ulcer on the left margin of the tongue. An incisional biopsy was performed, and histopathological examination confirmed the diagnosis, revealing a neutrophilic inflammatory infiltrate with components of eosinophils and lymphocytes. Considering the condition's reactive and inflammatory nature, we planned a corticosteroid treatment with intralesional injections of triamcinolone acetonide. This therapy delivers the active principle directly to the tissues beneath the ulcerative lesion. In three treatment sessions, we achieved the complete regression of the lesion's signs and symptoms. During a one-year follow-up period, no recurrences were reported. Conclusions: The scarcity of documented cases and the ambiguity of definitions in the scientific literature highlight the importance of clinical reports, which refine scientific knowledge about this condition. At the same time, we record an effective and non-invasive treatment that could facilitate healthcare professionals in managing these types of oral pathologies.
